Murinit® SP [FS]

Chemical Family: Polyphenylene Sulfide (PPS)

Murinit® SP [FS], thanks to the low fiber content and integrated solid lubricant, this high-performance material offers an excellent combination of good slide and wear behavior, high strength, and dimensional stability – even at high temperatures. Murinit® SP also has a good resistance to chemicals and hydrolysis.Production based on PPS-SP.
