PS (Polystyrene)

PS is a polymer made from styrene. Under normal conditions, it exists as a neutral colored,
semi-translucent pellet. In its pure form, polystyrene is hard with limited flexibility.

General purpose polystyrene (GPPS) is a clear crystal polymer that can have different properties,
such as melt flow index and chemical resistance.

High impact polystyrene (HIPS) contains about 5~10 percent of polybutadiene, which is grafted onto the styrene polymer.
