Polystyrene (PS) is classified into 3 groups. General Purpose Polystyrene (GPPS), Expanded Polystyrene (EPS) and High Impact Polystyrene (HIPS) is a versatile plastic that can be rigid or foamed.
GPPS is clear, hard and brittle. Its clarity allows it to be used in occasions when see-through ability is important – as in medical and food packaging, in laboratory ware, and in certain electronic uses.
