Introduction to polystyrene
Polystyrene is one of the oldest thermoplastic polymers produced industrially and is a versatile product with many uses. The advantages of this bright pure amorphous plastic are that it is easy to process, rigid, dimensionally stable and transparent, but its low impact strength limits its application. High impact polystyrene is made by grafting small amounts of polybutadiene onto a polystyrene matrix. It has an "island structure", a plastic matrix and a rubber dispersed phase. It has many characteristics: 1. Impact-resistant polystyrene is a thermoplastic resin; 2. It is odorless and tasteless, the material is hard, and the dimensional stability after molding is good; 3. Excellent high dielectric insulation; 4. Non-high-quality low water absorption material 5. Good gloss and easy to color.
high impact polystyrene
High-impact polystyrene, also known as HIPS, is a thermoplastic material made from elastomer-modified polystyrene. A two-phase system consisting of a rubber phase and a continuous polystyrene phase has developed into an important polymer commodity in the world. This general-purpose product has a wide range of impact properties and processing properties, allowing it to be used in a wide range of applications. Such as in the automotive, equipment, electrical products, furniture, household appliances, telecommunications, electronics, computers, disposable products, pharmaceuticals, packaging and entertainment markets.
Polystyrene Properties
The relative density of HIPS is 1.04~1.06, and the thermal deformation temperature is 70~84℃. The tensile strength of HIPS is about 15~30MPa, and the elongation is 35~60%. It increases with decreasing temperature and increasing strain rate, similar to rubber toughened systems. HIPS behaves somewhat like a viscoelastic solid and creeps when exposed to constant tensile stress. Creep decreases with increasing molecular weight and generally increases with increasing rubber content. The creep behavior of HIPS is strongly dependent on the average molecular weight (Mw). The bending strength is 29.4~50 MPa, the impact strength is 0.09~0.16N/M, the Vicat softening point is 84~100℃, and the melt index is 2~9g/10min. The heat resistance of a HIPS element depends on its shape, production conditions, heat source type and heating duration, and is also affected by the HIPS grade.
