General Classification Of Polystyrene
Polystyrene (PS) including GPS, expanded polystyrene foam (EPS), high impact polystyrene (HIPS) and syndiotactic polystyrene (SPS). Common polystyrene resin is nontoxic, odorless, colorless transparent
Particles, like the glassy brittle materials, its products with a very high degree of transparency, light transmission rate of up to 90% per cent, good electrical insulating properties, easy to be colored, processing and good liquidity, good rigidity and good chemical resistance. Lack of GPS is that brittle, low impact strength, prone to stress-corrosion cracking, resistance to heat poor and not boiling water.
