In addition, it has the strongest radiation resistance of all plastics.The most important feature of polystyrene is its excellent thermal stability and fluidity during melting, so it is easy to be molded, especially easy to be injected, and suitable for mass production.The forming shrinkage rate is small, and the dimensional stability of the forming products is good.Polystyrene is a polymer synthesized by free radical polymerization of polystyrene monomer.It is a colorless transparent thermoplastic with a glass conversion temperature above 100ºC, so it is often used to make all kinds of disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.
Polystyrene is colorless, transparent and can be colored freely. Its relative density is also second only to PP and PE. It has excellent electrical properties, especially good high-frequency properties, and is inferior to F-4 and PPO.
