Polystyrene is one of the oldest industrially produced thermoplastic polymers and is a very versatile product with a wide range of uses.The advantages of this bright, pure, amorphous plastic include ease of processing, rigidity, dimensional stability, and transparency, but its low impact strength limits its application.
High impact polystyrene is a small amount of polybutadiene grafted onto the polystyrene matrix.It has “island structure”, the matrix is plastic, and the dispersed phase is rubber.It has many characteristics:
1. Impact resistant polystyrene for thermal plasticity resin;
2. No odor, tasteless, hard material, good dimensional stability after forming;
3. Excellent high dielectric insulation;
4. Non-quality low-absorbent materials;
5. Its luster is good and easy to paint.
