Chemical name: polyvinyl benzol
General purpose polystyrene is a synthetic amorphous thermoplastic material, the polymerization product of styrene. Abbreviations for polystyrene in Russian are ПС, ПСМ, ПСС (PS, PSM, PSS), the foreign abbreviation is General purpose polystyrene (GPPS, PS, PS-GP).
General purpose polystyrene is a transparent hard, brittle material with low mechanical strength. Maximum operating temperature: 75-80 °C (individual grades operate at temperatures up to 105 °C). The glass transition temperature: 80-113 °C. Brittleness temperature: -60-70 °C. It has low moisture regain. It is characterized by high dielectric properties. It is radiation-resistant.
It is not resistant to UV radiation (UV radiation resistance is increased by introducing of special additives). Over time, a large drop in strength is observed.
It is resistant to water, dilute acids, alkalis and alcohols. It is not resistant to organic solvents and technical oils.

525M |
General purpose polystyrene is made by termic polymerization of styrene en masse. |
It is designed for the manufacture of items by injection molding, and coating production by coextrusion. |
It is produced in the form of transparent cylindrical granules, which are processed into finished products by injection molding or extrusion at the temperature 190-230 °C. Widespread use of polystyrene (PS) and polystyrene-based plastics is based on its low cost, easy processing and a huge range of different grades.
