White in colour. PS (Polysterol) is defined by a density range of 1050 kg / m3. It is a hard and solid plastic frequently used in products that require a certain rigidity, while offering greater elasticity and good shock absorption capacity.
PS polystyrene is a widely used type of fragile plastic. The computer you are using now is made of polystyrene. Transparent plastic cups, Polystyrene for packaging also made of polystyrene. Polystyrene, a polyolefin, is made up of styrene polymerized by free radicals. . Syndiotactic is a new type of polystyrene produced by metallocene catalytic polymerization. The two sides of the main chain are connectedalternatively with the benzene rings on polystyrene, while the benzene rings on ordinary polystyrene are connected randomly on both sides of the main chain. It is a versatile form of plastic used to make a variety of end-segment plastic products. The chemical formula used for PS is (C8H8) nThe melting point is ~240 °C (464 °F; 513 K) [4] For isotactic PS.
