General grade polystyrene is general-purpose polystyrene (GPPS) Polystyrene (PS) is polymerized from styrene monomer (SM) andcan be polymerized by a variety of synthesis methods. In industry, bulk polymerization and suspension polymerization are mainly used. The English name of polystyrene is Polystyrene, abbreviated as PS (hereinafter referred to as PS). PS is a thermoplastic amorphous resin, mainly divided into general-purpose polystyrene (GPPS, commonly known as transparent styrene), impact-resistant polystyrene (HIPS, commonly known as modified benzene) and expanded polystyrene (EPS) . 1. GPPS features GPPS is colorless,odorless, tasteless and shiny, transparent particles. Light weight, cheap, low water absorption, good adhesion, dimensional stability, good electrical properties, transparent products, easy to process. GPPS is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters but can only swell in acetone. Resistant to certain mineral oils, organic acids, alkalis, salts, lower alcohols and their aqueous solutions. It has low water absorption and can still maintain its mechanical properties and dimensional stability in humid environments. It has excellent electrical properties, high volume resistance and surface resistance, and is not affected by changes in temperature and humidity, nor is it affected by corona discharge. Radiation resistance is also very good. The main disadvantages of GPPS are that it is brittle and easy to crack, has low impact strength, poor heat resistance, cannot withstand boiling water, and can only be used at lower temperatures and lower loads. Poor sunlight resistance and flammable. It turns black when burned and has a special odor.
