GEHR Plastics PPS Polyphenylene Sulfide

Polyphenylene Sulfide (PPS)

GEHR Plastics Inc

产品说明：

The linear polyphenylensulfide belongs to the semi-crystalline materials and offers a very high mechanical capacity, thermal and chemical resistance distinguished at the same time, high dimensional stability, and creep strength. The LOI belongs to the highest of polymers. By the reinforcement with glass polymers strength is achieved, which is comparable with light metal. PPS closes the gap between the technical synthetics and PEEK with its strength and economy.

Properties

• very high strength and rigidity
• high hardness
• high thermostability
• high dimensional stability
• very high chemical resistance
• very good insulating properties
• high weather resistance
• high resistance to hydrolysis

Applications include components in machine-making, pump parts, fan parts, impellers, parts in the fuel and automotive sector.
