Product Description

Product Description

 

General Purpose Polystyrene is a kind of thermoplastic resin, is a colorless, odorless, 

tasteless, shiny, transparent beaded or granular solid. Density is 1.04 to 1.09,

 transparency is 88% to 92%, refractive index is 1.59 to 1.60. In the stress function,

 resulting in birefringence, the so called stress - optical effect. 

Product of the melting temperature is 150 to 180 ° C, thermal decomposition 

temperature is 300 ° C, the heat distortion temperature is 70 to 100 ° C, long-term use temperature is 60 ~ 80 °C
