Proside® Staple Fiber


Proside® PPS
polyphenylene sulfide fiber
Proside® PPS (polyphenylene sulfide) fibers combine moderate temperature resistance with excellent chemical resistance. PPS fibers also have very good flame resistance thanks to their high LOI. The low moisture regain of PPS often takes away from its use in apparel by causing the fiber to have an uncomfortable hand, but the good chemical resistance makes it very attractive for industrial applications and filtration.
