RECENT DEVELOPMENTS IN TWIN SCREWEXTRUDER DESIGN AND APPLICATIONS
Stuart Kapp, Leistritz
THURSDAY, DECEMBER 5, 2013
The twin screw extruder has been the primary device used in theplastics industry for continuous mixing of polymers, additives, andfillers for over 60 years. As with most modern-day plastics process-ing machinery, advancements in metallurgy, machining techniques,and machine controls have opened up new avenues for novelprocesses, resulting in even greater versatility for the end user.
The speaker will offer a timeline of twin screw extruder design, andcorresponding applications that have been performed on them.Topics to be discussed will include:
Early/initial designs of twin screw extrudersCo-rotating vs. counter-rotating extrudersThe evolution of the twin screw extruder shaftTorque vs. Free VolumeHeating & CoolingCompounding & PelletizingDirect sheet/film/profileContinuous mixing and processing of active pharmaceuticalsto improve bioavailability.

President’s Message
Another Loss/You Can Make A Difference
As many of you have heard, ourSection lost 3 contributors recently,Allen Niebuhr, Michael Reedy, andMarinos Xanthos. All have beenmemorialized by those who knewthem, and all will be missed. Justbefore Vinyltec 2013, the polymer
and specifically the PVC industry lost another con-tributor, Don Witenhafer. Many of you probably don’tknow who Don was, but let’s just say that his contri-butions to the PVC industry are second to none. Donwas a key contributor to BF Goodrich’s efforts toeliminate residual vinyl chloride monomer from thePVC manufacturing process. Some have specu-lated that without these contributions, the explosivegrowth of PVC has a plastics material might havebeen curtailed. Without the PVC industry theremight not have been a Palisades Section, and with-out the Palisades Section, perhaps no Palisades-New Jersey Section.
In 1973, the BF Goodrich Company announced thatthree PVC reactor cleaners at their Louisville plantdeveloped a rare form of liver cancer linked to expo-sure of vinyl chloride monomer. Proposed EPA reg-ulations (the first of their kind) and movements toban PVC resulted. The company instituted the CodeZero project with an unlimited budget; the goal tosave PVC resin production, the PVC industry andover 1 million jobs. What resulted were improve-ments in reactor coating technology eliminating theneed to clean the reactors, and the development ofsteam stripping technology to reduce VCM levels.Don was the lead inventor of both processes. Inter-estingly, BFG gave the steam stripping technologyto the industry saying that it was more important tosave the industry than to gain a competitive advan-tage over our competitors. For his role, Don wasinducted into the Plastics Hall of Fame in 2009.
More importantly, Don believed that anyone canmake a difference, and this was a theme that res-onated in talks he gave, and in my personal conver-sations with him. Today, many facets of the plasticsindustry are under one attack or another. Some ofthese attacks are based on junk science and use

scare tactics to elicit emotional responses. In hislifetime, Don made a difference—so can you.Maybe you won’t save an industry, but a differenceis still a difference. As the holiday season ap-proaches, these differences, no matter how small,just become more tangible, especially if on a per-sonal level. At this time of year we all talk of resolu-tions, let ours be that on behalf of Don, Marinos,Michael, and Allen; we make a difference.
On behalf of the Palisades-New Jersey Sectionplease enjoy a joyous and peaceful holiday season!

Al Whitney Wins 2013 Lifetime Achievement Award
for Contributions to the Vinyl Division and the Society of Plastics Engineers
Al (Alva) Whitney traceshis family lineage backto Eli Whitney (the fa-mous inventor of the cot-ton gin). Al’s grandfather
was a lab assistant toThomas Alva Edison, and Al
was named in Edison’s honor. Algraduated from the Newark College of Engineering(now NJIT) in 1936. He worked as a salesman, and thebulk of his career was spent with the Goodyear Corpo-ration in vinyl and related products. During World WarII, Al was instrumental in making sure the US govern-ment had a supply of the newly developed syntheticpolymer called “vinyl” for its experimental work. Al rec-ognized the need for improved vinyl properties, whichled to his association with the young chemist ElliotWeinburg of M&T Chemicals (Arkema). This associa-tion initiated the development of modern mercaptidestabilizers and the landmark patent in 1953; these sta-bilizers are still used today.
Al believes in SPE and the SPE objective and mission.Our section wouldn’t be where we are today withoutcontributions of members like Al Whitney. If not for Al,we might not have our Section at all. In 1962, the NewYork Section of the Society of Plastics Engineers re-fused to give PVC proper time at its meetings, and soAl started a petition to form the Palisades Section, whichwas chartered and launched in 1964. Al served as Pres-ident of the Section four times, and organized many ofthe committees that would form the basis of the Pal-isades Section. For example, along with Mel Gerson,he formed the Educational Endowment Committee andFund, which plays a significant role in what our sectionis able to do today to support students.
Al was instrumental during the VCM crisis at the land-mark Vinyltec conference that had over 1000 attendees.
He also worked on many other conferences hosted bythe Palisades Section, which was known as the locusof PVC within SPE. For many years, Al, Elliot, and DaveReilly were critical parts of the operational excellenceof the Palisades Section and the development of SPE.In 2008, Al worked on the committee that resulted in theformation of the current Palisades-New Jersey Section,and he continues to be active today, serving as anemeritus member of our BOD and Sponsorship Chair.
For 99 years, Al has defined excellence, and we salutehis accomplishments today! Within the Palisades-NewJersey Section, we will be renaming our High SchoolScholarships in his honor. From humble beginnings, Albuilt a legacy of excellence. He loves our Section andthe SPE, and it means a lot to him that it continues togrow and prosper. If you are not already a member, con-sider joining today.
Congratulations Al, and thank you!
Mark Lavach
Congratulations to Al Whitney, who is awarded the 2013 Lifetime Achievement Award for his contributions to theVinyl Division and the Society of Plastics Engineers. Although Al was not able to be present at
the Vinyltech meeting, Mark Lavach gave a speech, excerpted here, detailing some of Al’swork so that all present would be able to appreciate Al’s contributions to our industry.

Our Section and the Vinyl Division hosted Vinyltec lastmonth with a preconference seminar on Oct. 21 fol-lowed by two days of expert presentations, tabletop ex-hibits, and networking. Nearly 140 attendees alsoenjoyed a luncheon the first day, sponsored by Exxon-Mobil, where we heard a talk on our Economic Outlookby Bob Shrouds of DuPont (click here to view the fullpresentation). A reception that evening was hosted byPMC Group, and an awards luncheon the second daywas sponsored by Formosa Plastics. The award cere-mony featured a presentation of the Lifetime Achieve-ment Award to Al Whitney for his contributions to theVinyl Division and the Society of Plastics Engineers (seearticle p. 3). Dr. Yelena Kann of Metabolix was awarded“Best Paper” of the conference for her discussion, “PHACopolymers as Recycled PVC Property Enhancers.”
The conference started with a presentation by AllenBlakey of the Vinyl Institute, who reviewed the “threatand opportunity” of eco-labels (i.e., environmental per-formance certifications that may or may not be devel-oped with third-party objectivity). He reviewed thecurrent LEED version 4 program and noted that theVinyl Institute has appealed new credits for disclosingingredients and reformulating products because thosecredits insinuate that vinyl is hazardous and could neg-atively affect use. At the same time, PVC can fit intobuilding designs that win LEED credit (click here formore info on LEED v. 4). Applying the precautionaryprinciple and using other materials without adequate as-sessment is not as sustainable as slower change based ongood science and economic considerations, he concluded.
Rich Krock, technical director of the Vinyl Institute,shared comments on using PVC in sustainable designfrom an ANTEC® presentation, which is available on theVinyl Institute website (click here to go to website). Hediscussed how PVC can meet government goals for en-ergy efficiency, reducing greenhouse gases, waste re-duction and recycling, sustainable buildings, and waterconservation. PVC can also meet many of EPA’s “12principles of green chemistry” and has a superior life-cycle analysis to several other comparable buildingproducts. The Vinyl Institute sponsors an annual designcompetition with architecture students and conducts bi-weekly lunch-and- learn sessions with architects anddesigners at their offices to inform this group of today’sPVC attributes.
Rich Johnson, regulatory leader at Penn Color, followedthese discussions with a creative look at REACH and

the globally harmonized system (GHS) for safetydatasheets (SDS - the former MSDS). OSHA (althoughnot EPA) has adopted the GHS system, and newSDS/labeling will be required by June 2015. The USwon’t require the same classification of materials as theEU, but companies may choose to use the same clas-sifications. EU actions are thus highly likely to eventuallyaffect the US, he concluded. Regulatory issues have asignificant effect on PVC stabilizers, and presentationsby Anthony DiMaio of Galata Chemicals, Luis Cruz ofAM Stabilizers, and Henk Huisman of Chemson lookedat regulatory and technical developments and trends inPVC stabilizers.
In addition to many other excellent presentations, atten-dees heard the award-winning paper by Dr. YelenaKann of Metabolix discussing PHA copolymers thathave a new composition that is more compatible withPVC to allow use as recycled PVC property enhancers.Metabolix first introduced commercial PHA products forflexible and semirigid PVC in 2012, and is currentlyworking on a modifier for rigid applications. PVC recy-cling is an active area, and the modifier would improvethe properties of recyclate, particularly of mixed PVCwaste. In addition, as a biopolymer, PHA would improvethe “green” image of PVC.
Many thanks to all the presenters, and especially toConference Chairman Rich Bradley and to Joe Duska,Mike Fisch, Mike Carnese, Tom Martin, Bob Kappus,and Jay Kotak for all their work on this conference!

Student Article - Rutgers Chapter
At the most recent meeting of the Rutgers Universitystudent chapter of the Society of Plastics Engineers,students learned about a recent development in poly-mer technology and simulated polymer lab work viasmall-scale experiments.
To begin the meeting, chapter vicepresident Max Freedman gave ashort presentation on the applicationsof thermoplastic polyurethane em-bedded with graphene nanoribbons.Researchers at Rice University engineered this ma-terial to decrease the polymer’s gas permeability bya factor of roughly one thousand; they also discov-ered enhanced TPU mechanical properties, althoughthis was not their goal.
After the presentation was finished, students in thechapter made their way to a nearby lab for two exper-iments. For each, easily obtainable materials (vinegar,milk, etc.) were mixed according to well-definedrecipes. The first experiment produced a viscous liq-uid that cures over the course of three days; this liquidwas poured into small molds to simulate working witha polymer melt. The second experiment modeled thethree-dimensional bonding of polymer chains to formnetworks. Ingredients were mixed to form a solid,polymer-like material that can be rolled into a ball, andcures quickly at room temperature. Given enoughtime, the ball will cure so extensively that it gainssome bounce when dropped from an appropriateheight; essentially, the height to which it bounces is afunction of how well-cured it is.
The chapter’s future plans include having former pres-ident Giorgiana Giancola, who now has a Ph.D. andworks in the industry, give a talk on the transition fromuniversity to industry. A field trip to a polymer-relateddestination is also in the works.
