Polystyrene, which can be found in solid or foam forms, is a non-toxic hydrocarbon polymer.
It provides high machinability, electrical insulation, excellent resistance to water, acids, and shocks as well. Not providing a suitable environment for mildew and bacteria development make this material prominent.
Since it is one of the widely consumed plastics, several million tons of polystyrene are produced per year in the world. Although it is naturally colorless and transparent, polystyrene can be produced in various colors using colorants.
Features & Applications
