ZELLAMID® 1900 (Polyphenylene Sulfide), beige colour
PPS is a semi-crystalline engineering thermoplastic suitable for components demanding thermal stability up to 200°C, high dimensional stability and offers broad resistance to chemicals. PPS has good creep resistance at elevated temperatures. Moisture absorption in ZELLAMID® 1900 is negligible and so ensures that electrical insulating properties such as dielectric constant and dissipation (loss) factor are unaffected by wet or humid application conditions. ZELLAMID® 1900 has no known solvents below 200°C and is inert to steam, strong bases, fuels and acids. Unfilled PPS is not usually considered for bearing or other wear applications, but it has shown superior wear resistance in such applications involving aggressive chemical environments. PPS products are inherently flame retardant. ZELLAMID® 1900 GF40 offers better dimensional stability and thermal performance than unfilled ZELLAMID® 1900.
A lower cost alternative to PEEK in applications at somewhat lower temperatures.
