it can be dissolved in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones&esters, but it can only swelling in acetone. resistant to certain mineral oil, organic acid, alkali, salt, lower alcohol&water solution. the water absorption rate is low,&its mechanical properties&dimensional stability can still be maintained in the wet environment. the optical properties are second only to acrylic resin. the electrical properties are excellent, both the volume resistivity&the surface resistivity are very high,&are not affected by the changes of temperature&humidity,&are not affected by corona discharge. the radiation resistance is also good. its main shortcomings are brittle, brittle, low impact strength, poor heat resistance,&can not resist boiling water. it can only be used under low temperature&low load. the resistance to sunlight is poor&flammable. black smoke&spel odor when burning.

pps general - purpose polystyrene is a thermoplastic resin that is a colorless, odorless, tasteless, glossy, transparent bead/granular solid. the density is 1.04 to 1.09, the transparency is 88% to 92%,&the refractive index is 1.59 to 1.60. under the stress action, the birefringence is produced, that is, the so-called stress optical effect. the melting temperature of the product is 150~180 c, the thermal deco-ition temperature is 300, the thermal deformation temperature is 70~100,&the long-term use temperature is 60~80. at the lower temperature of 5~6, the stress can be eliminated&the thermal deformation temperature can be improved. if a little alpha methylstyrene is added to the production process, the heat-resistant grade of the general polystyrene can be improved.
