PS toughening, which material has better modification effect?

After PS toughening, it is called HIPS (High Impact Polystyrene), which refers to high impact polystyrene. Modification improves its impact toughness and reduces brittleness.

1.The application scope of HIPS is wide, mainly including the following key areas:

A. Packaging and disposables: HIPS is widely used in packaging materials and disposables, especially food packaging and tableware.

B. Instruments and household appliances: HIPS are used to manufacture small instruments, refrigerator walls and parts, TV housings, air conditioning components, commercial machines and audio and video tape cartridges.

C. Automotive interior: HIPS play an important role in automotive interior manufacturing and are often used to produce components such as dashboards and door panels.

D. Toys and entertainment products: Because of its excellent processability and impact resistance, HIPS are also commonly used in the production of toys and entertainment products, which need to be colorful and easy to process.

E. Construction industry: HIPS are mainly used in the construction field for decorative materials and components, such as flooring and signage.

2. Which material is good for PS modification?

For improving the performance of polystyrene (PS), the following materials are commonly used as modifiers:

A. K glue: This material has good transparency, but high hardness, toughness is not as good as SBS.

B. SBS: Due to its high butadiene content, SBS can effectively improve the toughness of PS, and the cost is low, so it is widely used.

C. SEBS: SEBS is mainly added to enhance the anti-aging ability of PS, and models with high styrene content are usually selected.
