PPS (Polyphenylene Sulfide) has a high-temperature resistance, chemical resistance, flowability, and dimensional stability.
Polyphenylene Sulfide (Ryton® PPS) is an engineered thermoplastic, that offers an exceptional balance of properties. PPS has a high-temperature resistance, chemical resistance, flowability, and dimensional stability. This makes PPS a useful material in electronics, automotive, aerospace, and chemical industries. The high temperature resistance in PPS consists of a long-term resistance to temperatures up to 200°C (392°F) and short-term resistance to temperatures up to 260°C (500° F). PPS plastic maintains dimensional stability at elevated temperatures and hard chemical environments. The dimensional stability in PPS allows even complex parts to be molded with tight tolerances. PPS also has a low water absorption and is insoluble in all common solvents below 200°C (392°F), making PPS stable in both typical and alternative automotive fuels. The molecular structure of a PPS polymer causes it to char during combustion, making it flame retardant.
PPS offers a unique combination of properties:
• Excellent hydrolytic stability
• Inherently self-extinguishing (UL 94 V0)
• Precision molding to tight tolerances with high reproducibility
• High stress cracking resistance
• Long-term and short-term thermal stability
• High modulus and creep resistance
• Dimensional stability
