Fortron 1342L4 PPS
linear PPS may be used with meltblown and spunbond technologies for melt spun nonwovens. Fiber and monofilament made from PPS can be found in woven or mesh conveyor belts, flame resistant clothing and filtration media. also offers unfilled, high viscosity PPS suitable for extrusion and compression molding to produce slabs, rods and other stock shapes commonly used for prototyping.PPS换热器
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。
Heat Exchanger
Drawing their heat supply from circulating water, the fresh air heating units in cars often incorporate a side section made from PPS. This side section is secured by the edge of the metal heat exchanger, which is crimped around it. Incorporated in the side section are the inlet and outlet connections for the water-antifreeze mixture. The service temperature extends up to 140°C. Only PPS has the necessary resistance to chemicals. This was determined by tests in a water-antifreeze mixture at 150°C over 1000 hours. PPS was the only material to display the strength previously specified. Its excellent mechanical properties, such as high strength values, moduli and low tendency to creep, meet the designers exacting requirements. PPS high dimensional stability makes it possible to meet the fine tolerances this application requires.PPS
PPS is a high-temperature linear PPS that offers excellent dimensional stability, inherent flame resistance, and excellent chemical and solvent resistance. PPS is insoluble in all known solvents below 200°C （392° F）. It also shows tremendous stability in both typical and alternative automotive fuels.
Standard injection moldable grades with glass fibers and/or mineral reinforcements are available, but many specialty grades are available for improved lubricity, low warpage, faster cycling and other areas of enhanced performance. Certain grades of PPS comply with ISO 10993 and USP Class VI, and Drug （DMF 14844） and Device （MAF-1097） Master Files have been created for them. These grades also meet European Directive 2002/72/EC for food contact applications and BfR （German Federal Institute for Risk Assessment , formerly BgVV, the German Federal Institute for Consumer Health Protection and Veterinary Medicine） standards.
