Polyphenylene sulfide fibers (PPS) are high-performance fibers with exceptional chemical and heat resistance, high dimensional stability, low moisture absorption, and high resistance to hydrolysis when exposed to acids, alkalines, and organic solvents. This fiber is generally resistant to most common chemicals. PPS has a melting point of about 285°C (545°F)

The fiber is used for applications where both excellent heat and chemical resistance is required. For example, PPS is used for high temperature filtration fabrics, also in hydrogen manufacturing etc…
