Polystyrene (PS)
Polystyrene is made by polymerising styrene monomer, a liquid petrochemical. It is a hard, solid thermoplastic at room temperature that softens and moulds easily when heated. Its durability and lightness are excellent, as are its insulation and damping properties.
Types of Polystyrene (PS)
Expanded Polystyrene (EPS)
Expanded polystyrene, also known as poliexpan, white cork or EPS, is derived from Polystyrene and is a lightweight foamed plastic material that is 98% air. It has high mechanical and moisture resistance, as well as excellent insulating and shock-absorbing properties.
High Impact Polystyrene (HIPS)
High impact polystyrene is made from standard Polystyrene (GPPS) and rubber, with the latter grafted onto the former. This additive gives HIPS better mechanical properties than GPPS, including higher impact strength and dimensional stability.
Standard Polystyrene (GPPS)
Standard polystyrene is obtained by polymerising pure polystyrene. It is considered one of the most transparent and glossy plastics. It is characterised by its rigidity, low thermal resistance, easy handling and high optical quality. It also has good dimensional stability.
Applications of Polystyrene (PS)
The main applications of polystyrene are electronic devices, insulation systems, cases, cassettes, coat hangers, household appliances, medical packaging and food packaging.
