High-impact polystyrene, also known as HIPS, is a thermoplastic material made of elastomer-modified polystyrene. The two-phase system composed of a rubber phase and a continuous polystyrene phase has developed into an important polymer product in the world. This general product has a wide range of impact properties and processing properties, making it widely used , Such as used in automobiles, appliances, electric products, furniture, household appliances, telecommunications, electronics, computers, disposable products, medicine, packaging and entertainment markets.High-impact polystyrene, a small amount of polybutadiene is bonded to a polystyrene matrix. It has a "sea-island structure", the matrix is plastic, and the dispersed phase is rubber. Has many characteristics:
1. Impact-resistant polystyrene is a thermoplastic resin;
2. Odorless, tasteless, hard material, good dimensional stability after forming;
3. Has excellent high-dielectric insulation;
4. It is a non-quality and low water absorption material;
5. Its gloss is good and easy to paint.
