Polyphenylene sulfide (PPS): semi-crystalline polymer belonging to the family of sulfides. The basic version is not very strong, so it is always compounded with fillers and or reinforcements. Falls into the category of super engineering plastics because it has very specific technical characteristics: it is inherently self-extinguishing (UL94 V0), also with regard to the thermal resistance (continuous use temperature of> 200 ° C and strain HDT> 250 ° C) and chemical resistance (contact with chemical agents). The versions with high filler content-reinforcements will also improve the tribological properties (low friction and wear).
Particularly suitable for the evaluation of metal replacement.
Because of the characteristics of high temperature is necessary to pay attention to the choice of equipment and settings of transformation.
