Engineered Polymers in Foam Extrusion

Energy management has been a global subject in the last two decades not only

for petroleum source but also for carbon cycle. There is only one earth; no

room for negotiation. International collaboration platform was in place and

continued to become more complex. It sure affected plastics industry in

different ways. For polymeric foam, it is, in general, more like opportunity than

setback. Blowing agent emission has no doubt been a burden for lot of foam

producers. However, it encouraged more research and development making

energy management more appealing. Foam became a popular core material

with skin as a sandwich composite for wind blade first, then lightweighting in

the market segment dominated by fiber reinforced polymers. In the editorial of

Aug. 2015, amorphous polyetherimide (PEI) foam was discussed in the aircraft

interior application. Under Ultem®, Sabic offered extruded PEI foam board

made with chemical blowing agent which not only expands but plasticizes PEI

to accomplish 20 times expansion in the extrusion process. Sabic also offers

Ultem® honeycomb for similar applications. Fig. 1 shows the extruded PEI

plank product.

Solvay offers extruded closed-cell polyphenylsulfone (PPSU) foam board and

sheet with density around 3 lbs/ft3, or ≈ 50 kg/m3. PPSU’s chemical structure

is presented in Fig. 2. This amorphous polymer has a density of 1.29 g/cm3.

This material exhibits thermal insulation properties better than low density

polyethylene plank, yet it shows thermal stability at prolonged exposure to

temperatures ranging from -40 oC to 204 oC. This thermoplastic foam board

possesses high mechanical modulus, thermoformability, and excellent damage

tolerance and fire resistance. Its ductility as illustrated in Fig. 3 can avoid

scoring which is necessary for most rigid structural foam; such as X-PVC foam.

For years, Solvay partnered with 3A Composite in structural applications. In

early 2016, this PPSU foam under TegraCoreTM obtained qualification

approval from Airbus to implement on its A350 XWB as a performance

lightweight material. The current challenge is in the die tooling and extrusion

processing to improve cell size and its uniformity, and more expansion.

Encountering challenge is inevitable in the civilization process. Determination

to overcome is a true character to survive, through which we all become

humble. Truly, it is from the surrounding we sharpen the endowed ability to

identify the mechanism and to make the most out of it and to live a life in

harmony. Without challenge, harmony may slide down to complacency. This

process would continue to humble us that we learn to fear the Creator to

become a good element in the long civilization process to make the society

better.

Abstract:

Ford has been developing and using

biomaterials in its vehicles for almost

two decades already. In North America,

soy foam is in every Ford vehicle;

coconut fiber backs trunk liners; recycled

tires and soy are in mirror gaskets;

recycled T-shirts and denim go into

carpeting; and recycled plastic bottles

become the REPREVE fabric first

applied in the 2016 F-150. And since 2013, the automaker has been working with several

companies, suppliers and universities to find applications for captured CO2.The new

foam is formulated by Novomer, a New York-based company that utilizes carbon dioxide

captured from manufacturing plants to produce innovative materials. Through a system of

conversions, Novomer produces a polymer than can be formulated into a variety of

materials, including foam and plastic that are easily recyclable.

Produced with up to 50 percent CO2-based polyols, the foam is showing promise as it

meets rigorous automotive test standards. Ford says that It could be employed in seating

and underhood applications, potentially reducing petroleum use by more than 600 million

pounds annually. The use of CO2-derived foam will further reduce the use of fossil fuels

in Ford vehicles and increase the presence of sustainable foam in the automaker’s global

lineup.

Abstract:

The effects of liquid-type additives on the morphology, thermal conductivity, and

synthesized with perfluoroalkane showed a smaller average cell diameter and a lower

thermal conductivity than PUR foams prepared with propylenecarbonate or acetone. The

Foam Update

average cell diameter of the PUR foams decreased from 228 to 155 μm and the thermal

conductivity decreased from 0.0227 to 0.0196 kcal/mh °C when the perfluoroalkane

content was 0.0 to 2.0 php (parts per hundred polyol by weight). The perfluoroalkane

likely acted as a nucleating agent during the formation of the PUR foams. The addition of

perfluoroalkane induced the smaller cells size of the PUR foams probably due to lower

surface tension of the polyol and perfluoroalkane mixture, resulting in high nucleation

rate. The smaller cell size appears to be the main reason for the improvement in the

thermal insulating and the mechanical properties of these PUR foams. The compressive

strength of the PUR foams prepared with perfluoroalkane was higher than the PUR foams

prepared with the propylenecarbonate and acetone. Based on the morphology, thermal

conductivity, and compressive strength, it is suggested that the perfluoroalkane is an

efficient liquid-type additive for the improving the thermal insulation of PUR foams.

Abstract:

Low density polypropylene based foams with different cellular structures have been

produced by the improved compression moulding route using a high melt strength

polypropylene as polymer matrix. In addition, different types of nanoparticles have been

introduced in the formulation (multi-wall carbon nanotubes, organomodified nanoclays

and natural nanoclays) to modify the structure and properties. The results have showed a

clear correlation between the open cell content of the foams and the mechanical

properties in compression. In the unfilled polypropylene high specific mechanical

properties are only achievable with low values of open cell content. In comparison, for an

equal value of the interconnectivity between cells, the samples containing nanoclays

present much higher specific properties. This result is attributed to the reinforcement of

these nanoparticles in the solid matrix, due to an improved exfoliation during the foaming

process and the presence of a bimodal cellular structure. The produced foams have

interesting properties with stiffness similar to those of commercial polymer foams used

for the core of sandwich panels.
