High impact polystyrene is also known as HIPS. Its overall properties are similar to PS; just as its name, its impact resistance remains superior in comparison with PS. However, after adding rubber to enhance the impact resistance, the transparence property disappears with HIPS.
Applications for HIPS includes radio shells, TV set cases, computer accessories, daily appliances, toys, kitchenware, stationary… etc.
Gin Wei’s HIPS is most suitable for injection grade.
