Polyphenylene sulfide (PPS) is resistant to oxidation, hydrolysis and hot steam. It can be used continuously at a temperature of + 230 °C and for short periods even up to + 260 °C. Its strength, stiffness and hardness properties are evaluated very well. Excellent heat dimensional and distortion resistance, low water absorption, excellent chemical resistance. Flame retardant and creep resistant. Its electrical properties make it a good insulator.
