virgin GPPS granules
Introduction of GPPS granules:
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
GPPS granules Characteristic:
High transparency, high temperature resistant and high strength
GPPS soluble in aromatic hydrocarbon, chlorinated hydrocarbon, aliphatic ketone and ester.
Resistant to some mineral oil, organic acid, alkali, salt, low alcohol and the role of the aqueous
solution.
Performance is excellent, volume resistance and surface resistance are very high, and not affected
by temperature, humidity change effects and also do not suffer the effects of corona discharge.
Radiation resistant performance is also very good.
