Keep it watertightDrinking water is a precious commodity. Making sure as little aspossible is lost is important and domestic water pipes must beguaranteed watertight for 50 years. Key to achieving this iseffective sealing.

Sealing requirements are demanding, as most new pipes are plasticand increasingly quick fit connections are used to speed fitment.When you consider still 70% of the world’s population do not haveaccess to clean drinking water, installation of water systems asquickly as possible, that are virtually leak free, is a major priority.And when most of those systems are required in the developingworld, minimizing cost is vital.

Sealing material development for water system applications hastherefore focused not just on performance but also on making costof production as low as possible. Which means to meet cost criteria,O-Rings need to be produced by injection molding.

To make injection molding of O-Rings possible, softeners are usuallyadded to the elastomer to give better flow of material into theinjection tool. The resulting better fill increases seal output andmakes production costs lower. But, softener may migrate into plasticcomponents such as pipes and quick connectors. This can lead tocracks in the plastic parts , which is not acceptable.

Busak+Shamban has solved this problem. We now have a broadrange of materials available that balance the use of softeners withmaterial performance. They also meet approvals to variousinternational standards, making them universally compliantglobally.

Grab your coatBusak+Shamban is a leader in coatingstechnology, identifying many treatments thatimprove the friction characteristics of ourseals. These aid automated assembly byhelping stop seals sticking together or twisting in their housing.

In food and beverage production coatingsmust be compliant with a number ofapprovals. One of our coatings, FF coating, hasrecently gained compliance with the standardsof the German Federal Environmental Agency(FEA), valid for the area D2 (seals). This is inaddition to its FDA compliance, making itsuitable for use in most food, beverage and drinking water applications.

FF Coating features:• Used at a thickness between 2-10µ• Water based• Solvent-free • Transparent • Operating temperature from -40ºC

to +150ºC (-40ºF to +302ºF)• Does not affect the seal’s natural elasticity• Suited for both static and low-level

dynamic applications, with infrequentmovement and short stroke rate.

Aiming to maximizesemiconductor equipmentperformance

At Busak+Shamban, we know that designers ofsemiconductor equipment want to maximizethe performance of the machines theymanufacture. Selecting the optimum sealmaterial and type can help ensure that. Usingthe right seal increases service life and extendsmeantime between planned maintenance(MTBM). This will reduce downtime, maximizeproduction efficiency, yields and processreliability, meaning overall, total cost ofownership is minimized for the customer.

The experience and range tooffer the right seal for the job

Busak+Shamban has lots of experience inproviding sealing solutions to semiconductorequipment manufacturers. This allows us torecommend the best possible option from ourextensive range of innovative seal materialsand products. Many of these are specificallyengineered to meet the increasinglydemanding requirements of the semiconductorindustry, giving exceptional sealing integrity.We are a one-stop-shop for the majority ofsealing needs, even the most difficult withinthis critical manufacturing process.

Semiconductorsealing one-stop-shop

Semiconductor manufacturing processes areextremely aggressive. Seals are often housed inareas of the processing system where they mustwithstand highly destructive liquids, gases andplasmas, at elevated temperatures or in vacuumconditions. To ensure long service life, equipmentdesigners must have available the right seals tostand up to the job.

Wet processapplications

Aggressive plasmasystems

These chemically intensive processes involve wetprocess chemicals including acids, such ashydrofluoric, alkaline solutions l ike sodiumhydroxide and solvents, typically N-methylpyrrolidoneor acetone. Wet manufacturing process steps include etching,stripping, plating and CMP (Chemical MechanicalPlanarization). These are followed by wafercleaning, removal of all surface contamination ofparticulates, organics, metallics and native oxidesand all liquids used must have extremely high purity.Optimum seal performance is critical in ensuringmaximum uptime throughout the ULSI (ultra largescale integration) process. A range of products isoffered that give almost universal chemicalresistance, minimum leach out of ionic impuritiesand extremely low particulation.

Plasma is used at various stages during waferfabrication. The plasma state is created when a gas issubjected to energy, breaking down its molecularintegrity and dissociating it into ions and electrons.Many of the gases used to do this in semiconductorprocesses are toxic, reactive and pyrophoric. It isessential that seals withstand this harsh plasmaenvironment where they will be subject to highenergy and possibly elevated temperatures.Inadequate sealing can lead to contamination andaffect product yield. Ultra pure sealing solutions fromBusak+Shamban ensure long-term reliability withminimal particulation and extremely low outgassing.

Semicon

Vacuum technology plays a critical role insemiconductor manufacturing, being key toprocess yield and productivity. Applicationsrange from dry pumps to more complexsubsystems for processes such asphotolithography. Maintaining a consistentvacuum is vital, as even minor fluctuations canhave a negative affect on the whole productioncycle.

Effective sealing is an important element inachieving this. Seals must not only be capableof sealing in a vacuum but also be able to

withstand corrosive gases, plasmas andaggressive media, often at high temperatures.Sealing is further complicated by possibleexposure to condensables and gels withoperation in oxidizing or reducingenvironments. They must demonstrate low levels of ionic impurities (anionic andcationic) and TOCs (Total Organic Carbon) with minimal particle generation, outgassingand permeation. On top of all of theserequirements is the need for supply of oftenspecialized seals to meet very short lead times,minimizing downtime.

Neville Sleigh manages the Researchand Development test faci l ity at Busak+Shamban associatedmanufacturing company TrelleborgSealing Solutions, Ashchurch inGloucestershire, England. From there, much of the development workhas been undertaken for a majorglobal semiconductor equipmentmanufacturer. Neville explains whathas been involved.

“When we started we were inunknown territory. As a company, wemay have been providing sealingsolutions for over fifty years but whenit came to solving the challenges thatsemiconductor manufacturingpresented, we faced something new.”

“Still though, basic principles ofeffective sealing could be applied.Finding a solution is al l aboutdefining the problem first. Weworked with our customer to identify

all those critical elements that mightaffect performance such as operatingpressures, temperatures and types ofmedia, gases and plasmas presentwithin the system. Then we needed to know other criteria specific to the application. In the case ofsemiconductor equipment, thatmeant l imitations on particlegeneration, outgassing, permeation, ionic impurities and TOCs.”

“To provide a unique solution, werequired unique testing capabilities.Over the last 15 years the companyhas invested heavily in purposedesigned and built one-off test rigsand undertaken extensive long-termtesting in conjunction with ourcustomers’ product developmentprograms. This was combined withdevelopment work in the virtualenvironment using advanced FEAmodeling. Through this methodologywe were able to prove a range ofsolutions that are now effectivelyoperating in semiconductorequipment globally.”

Busak+Shamban seals are used in rotarytransmission ‘lead-throughs’, fitted intothe tank filling systems.

Hydrogen filling stations, using WEHsystems and including Busak+Shambanseals, are being built at a number ofEuropean locations.

greenSealing

for aMaking hydrogen fueling possible

To make hydrogen fueling possible an effectivefilling system is required. Hydrogen is a veryvolatile fuel and extremely explosive when incontact with oxygen. A filling system musttherefore make sure there is no chance ofhydrogen mixing with oxygen, before it hitsthe fuel cell, if hydrogen fueling is ever goingto be successfully implemented.

WEH is a leader in fuelingtechnology

German company WEH has spent yearsdeveloping filling systems for alternative fuels.The latest patented system from WEH offersthe best possible safety for the user. The fillingnozzle is connected tightly, until there is nopressure in the space between the inlet valveand connector.

Higher pressure, bigger sealingchallenge

The higher the input pressure of a fillingsystem, the faster the tanks can be filled. WEHis developing a system that can fill the tank at an even higher pressure than the current450 bar (6525 psi). These pressures need high-performance seals, because the force toenergize the seals must be as low as possiblewhen the filling system is turned on.

Busak+Shamban seals selected

To meet operating requirements WEH chose agroup of seals, including PTFE seals, O-Rings,Stepseal® and Glyd Ring® in conjunction withBusak+Shamban as their sealing partner. Theseseals use standard Busak+Shamban materialsand also ones specially developed for thisapplication, including some capable ofwithstanding temperatures as low as

–40°C (-40°F).

alternativeThe search is on for an alternative fuel to gasoline. Not only do governments want to lessen our use of fossil fuels, whichare rapidly depleting, but they also want us to be greener. A major aim is to reduce the significant contribution vehicles have onglobal warming. The leading alternative atthe moment is hydrogen fueling.

What about global warming?

Global warming is caused by the collection ofcarbon dioxide emissions in the atmosphere. Theyact like a blanket, trapping in the sun’s heat. Thelargest source of carbon dioxide pollution is coalburning power plants; the second largest sourceis vehicles. Over the past 50 years average globaltemperatures have increased at the fastest rate inhistory. The consequences of this could becatastrophic. Extreme predictions are that largeareas of the world could become uninhabitable,with massive food and water shortages, sparkingwidespread migrations and war.

Is oil running out?

It is quite frightening when you realize howquickly we are using up the world’s fossil fuelreserves, considering we are all so dependent onoil for energy and transport. “Peak oil” is thepoint at which half the total oil, known to exist,has been consumed. Once this has been reached,though demand for oil is still forecast toincrease, production will steadily decline year onyear. This will cause prices to rise, not just for oilbut for its byproducts too. And at the momentestimates are for us to reach “peak oil”anywhere between now and 2020.

How hydrogen fuel cells work

A hydrogen fuel cell is a device that uses hydrogen andoxygen to create electricity. The type of fuel celltypically used in automotive applications is a PolymerElectrolyte Membrane (PEM). In this, hydrogen fuel ischanneled through flow plates to an anode on one sideof the fuel cell while oxygen is channeled to a cathodeon the other side of the cell. At the anode the hydrogenis split into positive hydrogen ions (protons) andnegatively charged ions (electrons). The protons passthrough the Polymer Electrolyte Membrane (PEM)directly to the cathode while the electrons are forcedalong an external circuit to the cathode, creating theelectrical current used for vehicle propulsion. At thecathode the protons and electrons mix with the oxygento form water, which flows out of the cell. Totally green,hydrogen fuel cells produce electricity with only waterand heat as byproducts.

is thechampion

One of our customers, a chemicalmanufacturer, put Isolast® sealsthrough some of the mostdemanding tests ever, for seals ofthis kind. Against all competition,they proved to be the winner,performing better than any otherFFKM material tested, in thesechemical immersion trials.

www.busakshamban.com/grooveMaterial leaflets at:

Isolast® performs well in demanding tests

The chemical company’s tests involved keeping Isolast® J9503 along with other competitive FFKMcompounds, immersed in various extremely aggressivechemical media for 112 days, at varying temperatures.After this time, the material volume was measured. Avolume increase of 20% is classed as a ‘critical thresholdvalue’ for seals in this type of experiment. Beyond that,the sealing material would not be considered suitablefor sealing in a chemical media, at the temperatureswhere a volume change above 20% was seen.

Isolast® J9503 proved to be an outright winner

Isolast® J9503 proved to be an outright winner in theseindependent tests to find the best performingperfluoroelastomer from a range of FFKM materials.Isolast® J9503 offered the best value in terms of cost andperformance compared to all other perfluoroelastomerstested.

Semicon

The new marketing team inMoscow has already madetheir presence known inRussia. They exhibited at lastyear’s International Oil andGas show and this year planto exhibit at NEF Gas.

The Russian oil and gas industry

Russia has the largest natural gas reserves inthe world and the eighth largest oil reserves.It is now the world’s largest exporter ofnatural gas and the second largest oilexporter; its economic growth over the lastfive years primarily being fueled by its energyexports.Oil reserves in Russia are known to be around60 billion barrels, most of which are locatedin Western Siberia, between the UralMountains and the Central Siberian Plateau.In 2004 liquids production was just above9 billion bbl/d with only Saudi Arabiaproducing more crude oil during that year.

Russia to increase oil & gasproduction

Around 70% of Russia’s production is exportedas crude oil, much transported to EasternEurope via its major export pipeline, theDruzhba (meaning friendship). Approximately30% of crude oil is refined locally in Russia’sforty plus refineries.Russia’s 1680 trillion cubic feet (Tcf) of naturalgas reserves is nearly twice that of the nextlargest country, Iran. The majority of gasproduction is through three major fields (calledthe 'Big Three') in Western Siberia - Urengoy,Yamburg, and Medvezh'ye. Historically mostnatural gas exports were to Eastern Europe butthis has diversified with supply now to the EUand emerging markets of Turkey, Japan andother Asian countries.Russia is expected to significantly increase oiland gas production, along with crude exportsby 2015. The expansion of gas production willbe primarily through the development of newfields with transportation eased by theNorthern Gas Pipeline, linking Russia directlywith Germany.

Gaining the seals ofapprovalBusak+Shamban has a range of sealmaterials that comply to NORSOK M-710standard

Busak+Shamban has been a leading supplier of sealingsolutions to the oil and gas industry for over twenty-fiveyears. To support their customers supplying the Norwegianoil and gas industry in gaining NORSOK approval for theirassemblies, Busak+Shamban has had a number of sealingmaterials tested to NORSOK standards.

We can now offer the largest range of sealing materialswith certificates of compliance to NORSOK M-710, availablefrom any seal developer and manufacturer. And most ofthese are already proven and in long-term use in manydemanding exploration, offshore and onshore production,upstream and downstream environments.

Bill Allan, Busak+Shamban Oil and Gas Segment Managersays, “We are thrilled to have been so successful in thesetests. The availability of compliant materials will make iteasier for existing and new customers to achieve fullapproval for their assemblies from NORSOK.”

The sealing materials are available in a range of seal types.The PTFE based materials are commonly used in theindustry in the form of Turcon® Variseal®, back up rings andsupport rings.

Details of tests:

A number of grades of Busak+Shamban polymers wereinvolved in rigorous independent tests, undertaken andsupervised by MERL - materials engineering researchlaboratory, a respected independent laboratory in theUnited Kingdom. The main focus of the testing was topredict service life of the materials within an offshoreworking environment, as specified in NORSOK M-710standard, Annex C. Ideally materials should exceedexpected well production lifetime of an oil and gas facilityof 30 years.Thermoplastic sealing compounds, PTFE based grades andPEEK based materials, were immersed in a sour (2% H2S)multi-phase fluid at +200°C to +220°C (+392°F to + 428°F),for periods of 7 to 70 days. After saturation in this liquidthe mechanical properties, including tensile strength,elongation Young’s modulus and volume changes, weremeasured. These results were used to predict ageing andestimated service life of the materials.

Summary of results:

All eleven thermoplastic materials tested met NORSOKacceptance criteria, showing them to have good chemicalstability. Changes in tensile strength remained well withinthe NORSOK acceptance range for thermoplastics and alleasily exceeded the 30 year expected well productionlifetime.

The NORSOK Standards

The Norwegian petroleum industry has developedthe NORSOK standards to ensure safety, add value toand improve cost effectiveness of petroleumindustry developments and operations. Usually the NORSOK standards are based onrecognized international standards withmodifications to specifically meet the needs of theNorwegian petroleum industry. One of theobjectives of these standards is to contributeNorwegian knowledge to improve internationalstandards.Different from previous approvals, is that allindividual components within an assembly mustmeet and be approved to NORSOK standards, ratherthan just the complete assembly. The preparation and publication of the NORSOKstandards is supported by OLF (The Norwegian OilIndustry Association) and TBL (Federation ofNorwegian Manufacturing Industries). NORSOKstandards are managed and issued by StandardsNorway.
