GPPS

General Purpose Polystyrene (GPPS) is a thermoplastic that is designed for applications requiring excellent electrical and mechanical properties together with good processability. Polystyrenes have well-balanced physical properties and are generally transparent, but available in various colors. 

Polystyrenes are usually processed by injection molding, but due to the material’s excellent processability, other methods work equally well, including blow and vacuum molding, thermoforming, extrusion or compression molding, and machining. PS grades are resistant to a wide variety of chemicals: alkalies, salts, lower alcohols, and weak acids. Polystyrenes also comply with FDA regulations.

PSPG has excellent transparency, good water resistance, and a high dielectric strength. It is widely used for laminated electronic circuits, high frequency insulation sheeting, insulators and other applications such as:

  • CD covers and cases
  • Razor blades holders
  • Plastic cutlery
  • Disposable Food Containers
  • Ceiling light panels, diffusers
  • Protective coverings
  • Electronic insulation, parts, components
  • Tank covers
