1.  High impact polystyrene (HIPS) is a tough plastic that has excellent impact strength, high stiffness and excellent Moldability but reduced transparency.

2.  HIPS is used for household appliances (TV housings, exterior of air-conditioner, etc.), office automation apparatus (housing for a copying machine, printer, etc.), toys, housewares, frozen food tray, bottles for a lactic acid drink, cups for ice cream, yogurt, tofu, etc.

3.  HIPS characteristics:-

1.   Low residual monomer
2.   Easy processing
3.   Good heat resistance
4.   High impact strength
5.   Base color stability
6.   Well-balanced mechanical properties with high impact and excellent flexural strength
7.   Super high impact
8.   High gloss with toughness
9.   Medium-impact with high heat resistance
10.   Applicable to Flame-retardant grade
11.   Excellent processability
