Xiamen Dacheng supplies ASA blister board and ODM & OEM processing service

ASA(English name: Acrylonitrile Styrene acrylate copolymer), engineering plastics, acrylic rubber and acrylonitrile, styrene graft copolymer. The molding temperature is 170-230°C.

Advantages of ASA:

1. ASA has good mechanical and physical properties

ASA and ABS are similar in structure and consist of acrylonitrile and butadiene rubber, itsThe excellent mechanical and physical properties of ABS as engineering plastics are retained..

2. ASA has strong weather resistance

If the polymer contains double bonds, the double bonds are easily opened by ultraviolet rays in sunlight with high energy intensity, thus causing the aging resistance of the polymer to decline. ASA replaces butadiene rubber containing unsaturated double bonds in ABS with acrylic rubber without unsaturated double bonds, so it can not only resist degradation, aging and fading caused by ultraviolet radiation, at the same time, it has a strong guarantee for the decomposition or discoloration caused by the high temperature in the oxidation process in the atmosphere, thus greatly improving 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 good high temperature resistance

4、ASA is an anti-static material, can make the surface less accumulation of dust

Application areas relate:

Automotive field:

ASA after a long time of wind erosion, as the special treatment of aging-resistant ABS as gradually gray (due to wind erosion or water flow caused by many micro cracks and cavitation on the surface). Typical applications for ASA are exterior mirrors, radiator grilles, rear baffles, lampshades, and other external components that withstand harsh conditions such as sun and rain, and strong wind. It is gradually extended to motorcycle panels, camping cars, small boat hulls, surfboards and other fields.

In the field of gardening:

ASA has proven particularly suitable for horticultural irrigation equipment as well as lawn cutter housings, etc.

Electrical and electronic field: It is preferred to be used in the housing of durable equipment, such as sewing machines, telephones, kitchen equipment, satellite antennas and other all-weather housings.

Construction field:

ASA/PVC blends are used for roof 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 advanced bathroom and sanitary products, hot and cold water exchangers, etc. due to its good surface quality and long-lasting stability in color, indicating that ASA also has corrosion resistance to cleaners and disinfectants.
