HIGH IMPACT POLYSTYRENE
High Impact Polystyrene (HIPS) contains rubber (Butadiene) and is particularly useful in the manufacturing of parts which require a high degree of impact resistance. In our range, we have HIPS suitable for Refrigerators (stress cracking resistance grade), High Gloss grade for glossy surface finish applications.
High Impact Polystyrene (HIPS) is generally used in the manufacturing of Refrigerator interiors, food trays & cups, electrical appliance components, TV and audio-visual equipment parts, automotive parts, toys, Instrument panels and fittings, gasoline tanks, computer housings, sheets & laminations, cutlery, medical appliances, fan parts, Air conditioner grills etc. Some major applications are:
