The most widely used version of toughened polystyrene is called high impact polystyrene or HIPS. Being cheap and easy to thermoform (see thermoforming), it is utilized for many everyday uses. HIPS is made by polymerizing styrene in a polybutadiene rubber solution. After the polymerization reaction begins, the polystyrene and rubber phases separate.
Polystyrene is manufactured in various forms that have different applications and can have medium to very low density. Extruded polystyrene (PS or xPS, sometimes colored pink/blue) is used in the manufacture of disposable cutlery, rigid ground contact rated insulating foam board, CD and DVD cases, plastic models of cars and boats, and smoke ...
In the mid-1990s the key challenge to durable plastic recycling was separation of impact resistant polystyrene, often called HIPS for High Impact Polystyrene from Acrylonitrile Butadiene Styrene (ABS). These two plastics types were commonly used and have overlapping densities that make density sortation alone insufficient.
CD case made from general purpose polystyrene (GPPS) and high impact polystyrene in the black portion (HIPS) High impact polystyrene (HIPS) was discovered by Charles F. Fryling in 1961. [19] HIPS is a low cost, plastic material that is easy to fabricate and often used for low strength structural applications when impact resistance ...
