HIPS is high impact polystyrene,a versatile brittle plastic, one of the cheapest engineering plastics. Impact-resistant PS has the advantages of easy processing, good performance and low price, so it is used to manufacture products and industrial products for many purposes. HIPS is a modified material of PS, which contains 5-15% rubber component in the molecule. Its toughness is about four times higher than PS, and its impact strength is greatly improved (high impact polystyrene). There are flame retardant grade, stress cracking resistance grade, high gloss grade, extremely high impact strength grade, glass fiber reinforced grade and low residual volatilization grade.
The largest specific use of HIPS is as packaging and disposablle materials, especially food packaging materials and dietary tableware. Such as daily packaging containers, vending machine and dispensing cups, various covers, plates, bowls and so on. Disposable items such as dishes, bottle caps, safety razors,pen holders, etc.
