PPS plastic is a thermoplastic special engineering plastic with excellent comprehensive performance. Its outstanding features are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. The linear PPS is crosslinked at 350 ° C or higher to form a thermosetting plastic, and the branched structure PPS is a thermoplastic. Next, let's get familiar with its performance.

PPS main performance:

1 heat resistance, its melting point exceeds 280 ° C, heat distortion temperature exceeds 260 ° C, long-term use temperature is 220-240 ° C. Degradation in air at 700 ° C at 40 ° C inert gas still maintains 40% weight, short-term heat resistance and long-term continuous use of thermal stability are better than all current engineering plastics. The specially modified varieties have a heat distortion temperature of over 350 °C.

2 Abrasion resistance can be greatly improved by filling a lubricant such as fluororesin and carbon fiber, and the friction coefficient is 0.01-0.02.

3 radiation-resistant radiation reaches Gy 1×108, which is a new material unmatched by other engineering plastics. It is the only ideal for radiation resistance in the fields of electronics, electrical, mechanical, instrumental, aerospace, aerospace, military, etc., especially atomic bombs and neutron bombs. material.

4 Good processing performance PPS resin has low melt viscosity, good fluidity, and easy to wet contact with glass fiber. Therefore, it is easy to fill filler. The glass fiber or inorganic filler prepared by it enhances injection-grade pellets and has high anti-stretching. Sex, impact resistance, resistance to bending and ductility. It can be uniformly formed above its melting point.

5 Good adhesion to metals and non-metals PPS has a very high bond strength to glass, aluminum, titanium, stainless steel, etc., and the adhesion reaches level 1. Good adhesion to glass, it is very suitable for lining of chemical equipment.
