White impervious pearl-shaped or granular High impact polystyrene
Purpose: HIPS are widely used in many appliances and industries because of their ease of manufacture and low cost. Major industries and markets include packaging, disposables, appliances and consumer appliances, toys and entertainment, construction products and decorations. The single biggest use of HIPS is packaging, particularly in the food industry, which accounts for more than 30% of consumption worldwide

1. Impact resistant polystyrene is thermoplastic resin;
2. Odorless, tasteless, hard material, good size stability after forming;
3. Excellent high dielectric insulation;
4. Non-quality low water absorption material;
5. Its luster is good and easy to paint.
