Листовой полистирол высокого воздействия Листовой пластик HIPS

Feature of HIPS plastic sheet, High Impact Polystyrene Sheet 
HIPS plastic sheet, High Impact Polystyrene Sheet the glass transition temperature is 80 to 90 ° C, the amorphous density is 1.04 to 1.06 g / cm3, the crystal density is 1.11 to 1.12 g / cm3, the melting temperature is 240 ° C, and the resistivity is 1020 to 1022 ohm · cm. Thermal conductivity is 0.116 W / (m · K) at 30 ° C. Common polystyrene is an amorphous random polymer with excellent heat insulation, insulation and transparency. The long-term use temperature is 0 to 70 ° C, but it is brittle and easy to crack at low temperatures. There are also isotactic and syndiotactic polystyrene. Identical polymers are highly crystalline。
What is the HIPS plastic sheet, High Impact Polystyrene Sheet ?
Обычный HIPS plastic sheet, High Impact Polystyrene Sheet resin is an amorphous polymer. The random arrangement of polystyrene macromolecular chains with benzene rings as side groups and large volume with benzene rings as side groups determines the physical and chemical properties of polystyrene, such as high transparency High rigidity. High glass transition temperature. Brittleness. Expandable polystyrene is made by impregnating a low-boiling physical foaming agent in ordinary polystyrene. It is foamed by heat during processing and is specially used to make foam plastic products. HIPS plastic sheet, High Impact Polystyrene Sheet is a copolymer of styrene and butadiene, butadiene is a dispersed phase, which improves the impact strength of the material, but the product is opaque. Syndiotactic polystyrene has a syndiotactic structure and is produced using a metallocene catalyst. It is a new type of polystyrene developed in recent years with good performance and belongs to engineering plastics.
