🔍 Product Description
GPPS 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.

💡 Application
GPPS can be used for daily necessities, electrical equipment, instrument casings, toys, lamps, household appliances, stationery, cosmetic containers, indoor and outdoor decorations, fruit trays, optical parts (such as prisms, lenses), lens windows, mirrors and molding, car lights, telecommunications accessories, film capacitors for high frequency, high-frequency insulating materials, televisions and other containers, waveguides, chemical containers, etc. Suspended polymer resins can be made into foam plastics of different densities, used as insulation, soundproofing, shockproof, floating, packaging materials, substitutes for cork, pre-foamed bodies can be used as water filtration media and for preparing lightweight concrete, and low-foaming plastics can be made into synthetic wood for furniture, etc.
