PPS Polyphenylene Sulfide Series - Suzhou Mingrise Materials Technology Co., Ltd.

PPS Polyphenylene Sulfide Series

PPS (Polyphenylene Sulfide), also known as "plastic gold," is a semi-crystalline new high-performance thermoplastic resin featuring high mechanical strength, high temperature resistance (long-term service temperature of around 220°C), chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties. PPS-ST uses PPS as the matrix and incorporates high-performance glass-fiber reinforcement, significantly improving the rigidity and strength of the material, though its toughness is lower than that of pure PPS.

Material Properties Table

Key Features

Excellent dimensional stability owing to low coefficient of linear expansion and low water absorption
Continuous use temperature up to 220°C; however, the glass transition temperature is only 90°C — use caution under high load at high temperature
Excellent fatigue and creep resistance
Stable dielectric constant and dielectric loss over a wide frequency range

Application Areas

Widely used in semiconductors, aerospace, automobile manufacturing, medical devices, energy, industrial and other fields.
