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
