Description

Injection Molding Grade(GPPS)

Sinopec PS injection molding grade has good rigidity, light transmittance, corrosion resistance, eletrical insultion property and dyeability. It features low shrinking rate, good molding and processing properties and short molding cycle time. In addition, it allows high-speed injection molding and products made from it have excellent dimensional stability.

Introduction of GPPS:
General Purpose Polystyrene is a kind of thermoplastic resin, is a colorless, odorless, tasteless, shiny, transparent beaded or granular solid. Density is 1.*4 to 1.*9, transparency is *8% to *2%, refractive index is 1.*9 to 1.*0. In the stress function, resulting in birefringence, the so-called stress - optical effect. Product of the melting temperature is **0 to **0 ° C, thermal decomposition temperature is **0 ° C, the heat distortion temperature is *0 to **0 ° C, long-term use temperature is *0 ~ *0 ° C
