High strength and chemical resistance

Polyphenylene sulphide are sulphurous aromatic high-performance plastics, which are produced from phynylmercaptan. Due to their high long-term temperature application ability of +260 °C and the excellent chemical resistance, they are among the most important high-performance plastics. They are oxidation and hydrolysis resistant and possess a low coefficient of sliding friction. Polyphenylene sulphides are oft en used in electrical engineering.
