Introduction to polystyrene

Polystyrene is one of the oldest industrially produced thermoplastic polymers and a very versatile product with a wide range of uses. The advantages of this bright, pure amorphous plastic are that it is easy to work, rigid, dimensionally stable and transparent, but its low impact strength limits its applications.
High impact polystyrene is made by grafting a small amount of polybutadiene onto a polystyrene matrix. It has "island structure", plastic matrix and rubber dispersed phase. It has many characteristics:
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.

High impact polystyrene

High impact polystyrene, also known as HIPS, is a thermoplastic material made from elastomer modified polystyrene. The two-phase system consisting of rubber phase and continuous polystyrene phase has developed into an important polymer commodity in the world. This universal product has a wide range of impact properties and processing properties, making it a wide range of applications. Such as used in automotive, equipment, electric products, furniture, household appliances, telecommunications, electronics, computers, disposable products, medicine, packaging and entertainment markets.

Polystyrene properties

HIPS relative density is 1.04~1.06, thermal deformation temperature 70~84℃. HIPS tensile strength is about 15~30MPa, elongation is 35~60%. It increases with the decrease of temperature and the increase of strain rate, similar to rubber toughening system. HIPS behave somewhat like viscoelastic solids and creep when exposed to constant tensile stress. Creep decreases with increasing molecular weight and generally increases with increasing rubber content. The HIPS creep behavior is strongly dependent on average molecular weight (Mw). The bending strength is 29.4~50 MPa, the impact strength is 0.09~0.16N/M, the veka softening point is 84~100℃, and the melt index is 2~9g/10min. The heat resistance of HIPS components depends on their shape, production conditions, type of heat source and duration of heating, and is also affected by the HIPS class.
