High- Impact Polystyrene is a type of synthetic polymer that is made from styrene monomer. This type of polymer is known in the industry as HIPS. Polystyrenes are produced in three types: general, high-impact and expanded. The melting temperature of the high-impact is around 240 degrees Celsius.
Polystyrene is one of the main materials for making all kinds of accessories in the industry. High-impact polystyrene is one of the 5 main industrial resins. This polymer has industrial uses in electronic industries, construction compounds and household appliances industry. It also has a very high resistance to moisture absorption and is very suitable for food packaging. This polymer is not suitable for use above 85 degree Celsius.
