1, ASA has good mechanical and physical properties

ASA and ABS are similar in structure, composed of acrylonitrile and butadiene rubber, which retains the excellent mechanical and physical properties of ABS as an engineering plastic.

2, ASA has strong weather resistance

If the polymer contains double bonds, the double bonds are easily opened by the ultraviolet rays in the sunlight with higher energy intensity, which will cause the degradation of the aging resistance of the polymer. However, ASA does not require Acrylic rubber containing unsaturated double bonds replaces the butadiene rubber containing unsaturated double bonds in ABS. Therefore, it can not only resist degradation, aging and fading caused by ultraviolet radiation, but also cause high temperature in the oxidation process in the atmosphere. The decomposition or discoloration of the material has a strong guarantee, which greatly improves the anti-aging and weather resistance of the material. According to the test results, the anti-aging performance of ASA is more than 10 times that of ABS.

3, ASA has relatively good high temperature resistance

4. ASA is an anti-static material, which can reduce the accumulation of dust on the surface

Application fields of ASA

Automotive field

As a result of long-term wind erosion, ASA will not gradually turn gray like specially treated aging-resistant ABS (there are many micro-cracks and cavitations on the surface due to wind erosion or water flow). Typical applications of ASA are exterior components such as exterior mirrors, radiator grilles, tail baffles, lampshades, etc., which are exposed to harsh conditions such as sunlight, rain, and strong winds. At present, it has gradually extended to motorcycle panels, camping cars, small boat hulls, surfboards and other fields.

Horticulture field

ASA has proven to be particularly suitable for garden irrigation equipment and lawn cutter housings.

Electronic and electrical fields: It is preferentially used in the shell of durable equipment, such as: sewing machines, telephones, kitchen equipment, satellite antennas and other all-weather shells.

Architecture field

ASA/PVC blends are used for roofing panels and window materials. In this regard, foreign countries have more than 10 years of practical application experience.

In the United States, ASA has been widely used in high-end bathroom and sanitary products, hot and cold water exchangers, etc. due to its good surface quality and long-lasting color, which shows that ASA also has corrosion resistance to detergents and disinfectants.
