What is ASA material?
Impact Modified Resin
ASA is a terpolymer consisting of acrylonitrile, styrene and acrylate, and is an impact modified resin. ASA materials have excellent weathering, heat and chemical resistance properties, which makes them widely used in construction, automotive and outdoor products.
Chemical composition and structure
ASA is an amorphous polymer formed by the co-polymerization of styrene, acrylonitrile and acrylate rubber bodies. It is made by graft copolymerization of acrylates as the main chain with acrylonitrile and styrene monomers.
Physical Properties
ASA material has excellent mechanical and physical properties, including high impact strength, good heat resistance and chemical stability. It can be exposed to sunlight for 15 months without changing color, and the impact strength and elongation at break are almost unchanged. In addition, ASA material has good flame retardancy and anti-static properties, which can reduce the accumulation of dust.
Application Areas
Construction industry: ASA materials are commonly used in roof tiles, wall panels, solar water heaters and other outdoor construction and decoration materials due to their excellent weather resistance and heat resistance.
Automotive industry: ASA materials are mainly used in automobile manufacturing for exterior pillars, mirror housings, spoilers, grilles and other parts, and their no-spray characteristics reduce production costs and environmental pollution.
Outdoor products: ASA materials are widely used in gardening and irrigation equipment, power tools, sports equipment, etc., due to its excellent weather resistance and long-term practicality.
Manufacturing process and market situation
ASA materials are mainly produced through injection and extrusion molding processes. Major suppliers in the market include companies such as BASF (Germany), Hitachi Kasei (Japan), and GE (U.S.), which offer different models of ASA resins and alloys on a global scale.
