DIC.PPS FZL-4033 PPS
FZL-4033 is a glass fiber and poly tetra fluoro ethylene filled PPS compound that provides low friction and wear resistance.
Fuel Cell End Plates
Injection-molded end plates made from ’s polyphenylene sulfide （PPS） can provide significant cost and weight savings in proton exchange membrane （PEM） fuel cells. Design changes integrating the end plate and the adjacent insulating plate may reduce cost and weight as much as 90% compared to current fuel cell prototypes employing metal.A PEM fuel cell assembly contains a stack of about 200 series-connected cells. The stack is held together through bolting from the end plates to hold the bipolar plates in the stack together and compress the gaskets between them. Intervening insulating plates have bored manifold to feed hydrogen fuel, oxidizing air and cooling water to the stack, as well as to remove the water produced during cell operation. Even with automated machining, the two sets of plates can cost from $300 to $500. ’s development work suggests that integrated injection-molded plates combining end and insulating components may reduce plate cost to between $100 and $120 per stack while also reducing stack weight by at least 10 lb （4.95 kg）.
PPS換熱器
本方部分抵押的金屬換熱器，這是它周圍的卷曲的邊緣。側面部分納入水防凍劑的混合物的進口和出口連接。延伸服務溫度高達140°C 只有聚苯硫醚具有必要的抗化學品。這是由水防凍液混合測試確定在150℃以上1000小時。聚苯硫醚是*的材料顯示先前的力量。其優良的機械性能，如高強度值，彈性模量和低蠕變傾向，滿足設計師的嚴格要求。聚苯硫醚的尺寸穩定性高，使得它能夠滿足此應用程序需要精細的公差。使用聚苯硫醚1140L4原因.借鑒他們的供熱循環水，清新的空氣在汽車中的供熱單位往往納入聚苯硫醚，從一個側面部分。
Aerospace Wing and Leading Edge Nose
The trick was to create suitable structural elements embodying these attributes. This is done by extruding the PPS into film, combining it with chosen fibrous reinforcements and forming the final part under high pressure at 300°C （572°F）.Individual parts are then fabricated from the pressed composites and welded together in an autoclave to form the final component as one piece.Fiber-reinforced composites based on ’s high performance polyphenylene sulfide （PPS） make an important contribution to weight reduction of the Airbus A340 and A380.This helps lower fuel consumption and increase range and passenger capacity.PPS already had all the basic characteristics for use in aircraft construction – resistance to high temperatures and aggressive chemicals, hardness, impact strength, dimensional stability and inherent flame-retardancy.
