GPPS

General purpose polystyrene is produced by polymerization of the monomer styrene. It is a transparent solid product made from 2 to 5 mm pellets. More elastic, GPPS or crystal-clear polystyrene, is fully transparent, yet more fragile. It is widely used in food packaging applications or jewel cases.

General purpose polystyrene is extremely versatile, and its relatively low cost makes it ideal for a wide range of applications.
