Polyphenylene Sulfide - outstanding heat resistance, chemical resistance and dimensional stability.
PPS (Polyphenylene Sulfide) - outstanding heat resistance, chemical resistance and dimensional stability. High-temperature specialty plastic for industrial use.
PPS is a semi-crystalline high-performance plastic that combines outstanding heat resistance with exceptional chemical resistance. It withstands nearly all industrial chemicals at temperatures below 200°C. PPS plastic offers excellent dimensional stability and minimal moisture absorption.
PPS's inherent flame retardancy (UL94 V-0 without additives) makes it a safe choice for demanding applications. Available in unfilled and glass-fiber reinforced grades.

PPS's outstanding heat and chemical resistance make it ideal for demanding industrial applications.
Pump parts, valve seats and seals in aggressive chemical environments.
Heat-resistant parts in engine compartments and exhaust systems.
Electrical insulators and connectors that withstand soldering temperatures.
Sterilizable parts and components that withstand repeated wash cycles.
We supply PPS in unfilled and glass-fiber reinforced sheets, rods and tubes.
PPS plastic stands out from other engineering plastics particularly due to its heat and chemical resistance. Here is a comparison with the most common alternatives:
POM offers better sliding friction and wear resistance, but PPS withstands significantly higher temperatures (220°C vs 100°C) and provides better chemical resistance. Choose PPS when temperature or chemicals are a challenge.
PEEK withstands higher temperatures (250°C vs 220°C) and is tougher, but PPS is significantly more affordable and offers better chemical resistance to many solvents. PPS is often a cost-effective alternative to PEEK.
PTFE offers a lower coefficient of friction and better chemical resistance, but PPS is mechanically much stronger and stiffer. PPS is better suited for structural parts at high temperatures.
Outstanding heat resistance (220°C continuous), exceptional chemical resistance, inherent flame retardancy (UL94 V-0), very low moisture absorption. Available in sheets, rods and tubes.
PPS (polyphenylene sulfide) is a semi-crystalline high-performance plastic known for its outstanding heat and chemical resistance. It withstands continuous use up to 220°C and resists nearly all industrial chemicals.
PPS plastic is used for chemical industry pump parts and valves, automotive heat-resistant components, electronics connectors and insulators, and sterilizable food industry components.
PEEK withstands higher temperatures (250°C vs 220°C) and is tougher, but PPS is significantly more affordable and offers better chemical resistance to many solvents. PPS is often a cost-effective alternative to PEEK.
Yes, PPS is inherently flame retardant and achieves a UL94 V-0 rating without flame retardant additives. It does not ignite easily and produces minimal smoke.
