Introduction to GPPS
GPPS are shiny, transparent particles. Light, cheap, low water absorption, good coloring, dimensional stability, good electrical properties, transparent products, easy processing. GPPS is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters but only dilates in acetone. It is resistant to some mineral oils, organic acids, bases, salts, low-level alcohols and their aqueous solutions. Low water absorption, can still maintain its mechanical properties and dimensional stability in wet environment. Excellent electrical performance, high volume resistance and surface resistance, and not affected by temperature, humidity changes, also not affected by corona discharge. Radiation resistance is also very good.
application
General-purpose polystyrene, can be used in daily necessities, electrical, instrument casings, toys, lamps, household appliances, stationery, cosmetic containers, indoor and outdoor decorations, fruit trays, optical parts (such as prisms, lenses), lens, window mirrors and molding, automotive Lamps, telecommunication accessories, film of capacitors for electric frequency, high frequency insulating materials, containers for TV sets, waveguides, chemical containers, etc. Suspension polymer resin can be made into foamed plastics of different densities, used as thermal insulation, sound insulation, shockproof, floating, packaging materials, cork substitutes, pre-foamed bodies can be used as water filter media and light-weight concrete preparation, low-foaming plastics can be made into synthetic wood for furniture, etc.
