Material Notes:

The linear polyphenylensulfide belongs to the semi-crystalline materials and offers a very high mechanical capacity, thermal and chemical resistance distinguished at the same time, high dimensional stability, and creep strength. The LOI belongs to the highest of polymers. By the reinforcement with glass polymers strength is achieved, which is comparable with light metal. PPS closes the gap between the technical synthetics and PEEK with its strength and economy.Propertiesvery high strength and rigidityhigh hardnesshigh thermostabilityhigh dimensional stabilityvery high chemical resistancevery good insulating propertieshigh weather resistancehigh resistance to hydrolysisApplications include components in machine-making, pump parts, fan parts, impellers, parts in the fuel and automotive sector.
