PPS Engineering Plastics — A Comprehensive Guide to Polyphenylene Sulfide

What Is PPS?

Polyphenylene Sulfide (PPS) is a high-performance engineering thermoplastic known for outstanding chemical resistance and thermal stability.

關鍵特性

• Continuous Service Temp: 200–220°C
• Melting Point: 280°C
• Chemical Resistance: Exceptional — resists acids, bases, solvents
• UL94 Rating: V-0
• Hydrolysis: Excellent resistance

應用

PPS is used in automotive under-hood components, industrial pump parts, electrical connectors, and medical devices requiring sterilizability.

Grades Available

• Unfilled: Maximum toughness
• GF30/40%: Glass fiber reinforced for stiffness
• CF10/30%: Carbon fiber for wear resistance
• PTFE-filled: Self-lubricating grades
