PS can be divided into two categories: general-purpose polystyrene and high impact polystyrene. GPPS, taking on a transparent and crystal form, has many grades with the difference of molecular weight. HIPS contains 5% elastomer for the purpose of enhancing impact intensity. PS is primarily applied to electric appliance, automobile, film and packaging, architecture material, toy, household items and etc.
