Fortron 1140L7 PPS
f your design challenges require high temperature stability, broad chemical resistance, stiffness, strength and creep resistance at elevated temperature, consider Polyphenylene Sulfide （PPS）.Fuel Cell End Plates
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）.Injection-molded end plates made from ’s polyphenylene sulfide （PPS） can provide significant cost and weight savings in proton exchange membrane （PEM） fuel cells.
PPS换热器
使用聚苯硫醚1140L4原因.借鉴他们的供热循环水，清新的空气在汽车中的供热单位往往纳入聚苯硫醚，从一个侧面部分。本方部分抵押的金属换热器，这是它周围的卷曲的边缘。 侧面部分纳入水防冻剂的混合物的进口和出口连接。延伸服务温度高达140°C 只有聚苯硫醚具有必要的抗化学品。这是由水防冻液混合测试确定在150℃以上1000小时。聚苯硫醚是*的材料显示先前的力量。其优良的机械性能，如高强度值，弹性模量和低蠕变倾向，满足设计师的严格要求。聚苯硫醚的尺寸稳定性高，使得它能够满足此应用程序需要精细的公差。
Aerospace Wing and Leading Edge Nose
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. 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）.
