AS, full name Acrylonitrile-Styrene Copolymer, is a copolymer of acrylonitrile and styrene, widely used in the field of chemical production raw materials. This article will detail the nature and use of.

1. AS properties

1. Physical properties

AS is a colorless and transparent thermoplastic resin with high hardness, rigidity and heat resistance. Its density is about 1.05g/cm³, the glass transition temperature range is 70-105 ℃, and the heat distortion temperature range is 80-110 ℃. AS has good dimensional stability and is not easy to deform due to temperature changes. In addition, AS also has excellent electrical insulation properties and chemical resistance.

2. Chemical properties

AS has certain oil resistance, water resistance and acid and alkali resistance. However, under the conditions of strong acid, strong alkali and high temperature, AS will decompose. In addition, AS also has good weather resistance and can be used outdoors for a long time.

2. AS USES

1. Home appliance

AS has a wide range of applications in home appliances, such as washing machines, refrigerators, air conditioners and other shell and internal parts. Because of its high heat resistance, hardness and rigidity, it can meet the material performance requirements of household appliances.

2. Automotive industry

AS also has a wide range of applications in the automotive industry, such as automotive lamps, dashboards, interior trim parts, etc. AS has excellent weather resistance and chemical resistance, and can maintain stable performance in harsh automotive operating environments.

3. Construction industry

In the construction industry, AS is mainly used to make doors and windows, pipes, decorative panels, etc. Because of its good heat resistance, weather resistance and chemical resistance, it can improve the service life and safety of construction products.

4.

of electronic and electrical appliances In the field of electronic and electrical appliances, AS is often used to make electrical sockets, switches, wire insulation layers, etc. Its excellent electrical insulation performance and heat resistance can meet the requirements of electronic and electrical products for material performance.

In conclusion, AS, as a copolymer of acrylonitrile and styrene, has a wide range of applications in the field of chemical production raw materials. Its excellent physical and chemical properties make AS an important material in the fields of home appliances, automobile industry, construction industry and electronic appliances.
