PS Polystyrene Chemical and Physical Properties: Most commercial PSs are transparent, amorphous materials. PS has very good geometric stability, thermal stability, optical transmission characteristics, electrical insulation properties and a very small tendency to absorb moisture. It is resistant to water, diluted inorganic acids, but can be corroded by strong oxidizing acids such as concentrated sulfuric acid and can swell and deform in some organic solvents. Typical shrinkage is between 0.4 and 0.7%.

Injection molding process conditions:
Drying treatment: Drying is usually not required unless stored improperly. If drying is required, it is recommended to dry at 80C for 2-3 hours.
Melting temperature: 180~280C. The upper limit for the flame retardant material is 250C. Mold temperature: 40~50C. Injection pressure: 200~600bar.
Injection speed: A fast injection speed is recommended.
Runners and gates: All conventional types of gates can be used. Typical use product packaging, household items (tableware, trays, etc.), electrical (transparent containers, light source diffusers, insulating films, etc.).
