What is Acrylonitrile Styrene Acrylate (ASA)?

ASA was originally developed as an alternative to acrylonitrile butadiene styrene (ABS). Both materials have similar mechanical properties and structures, but ASA is formulated by introducing a grafted acrylic ester elastomer (in the form of a powder) during the copolymerization of acrylonitrile and styrene. Formulating ABS, on the other hand, requires butadiene rubber. ASA also lacks double bonds, which makes this material more resistant to weathering, heat, chemicals, and UV radiation.

Popular Applications for ASA

Given its resistance to impact, chemicals, weather, and UV light, ASA plastic material is often used in outdoor applications like commercial siding, plastic roof tiles, Co-extrueded with WPC floor, deckings, electrical housings; outdoor furniture; and sports, lawn, and garden equipment.

Manufacturers in the #automotive industry use ASA in everything from #car exterior panels to side-view mirror housings due to its strength and durability. For similar reasons, many product teams use ASA when creating jigs, fixtures, and other manufacturing aids.

Since ASA comes in the form of resin, filament, films, or sheets, it can be used for a wide variety of manufacturing processes like #3D printing, thermoforming, injection molding, structural foam molding, and extrusion blow molding. You can also co-extrude ASA filament alongside other polymers. In this case, only the ASA layer could be exposed to high temperatures and weathering.
