Asa plastic sheet.

Acrylonitrile styrene acrylate or asa for short is a modified form of san where acrylic ester elastomer aka rubber phase has been introduced during copolymerization. Its mechanical properties are very similar to acrylonitrile butadiene styrene abs elastomers. Base asa resins are sold under the trade names luran s basf plastic materials geloy general electric plastics and centrex monsanto chemical co. When it comes to yellowing and gloss retention asa is significantly better than abs which.

Asa can be considered a uv resistant version of abs with its excellent weather ability and heat resistance. Low levels of yellowing are extremely important for applications where long term aesthetic and appearance is important. Acrylonitrile styrene acrylate asa also called acrylic styrene acrylonitrile is an amorphous thermoplastic developed as an alternative to acrylonitrile butadiene styrene abs but with improved weather resistance and is widely used in the automotive industry. Acrylonitrile butadiene styrene acrylonitrile styrene acrylate abs asa is a material with great toughness and rigidity dimensional stability abrasion resistance chemical resistance and can perform well under various temperatures.

Order in asa. The resulting modified resin is similar to san and abs plastics but with greater resistance to weathering making it ideal for outdoor applications. The natural color of asa in off white but the material can be colored. Not only can the physical performance of a part deteriorate but yellowing reduction in gloss and discolouration can also occur.

This type of copolymer has excellent resistance to uv irradiation it also has good chemical resistance and high impact strength. It is an acrylate rubber modified styrene acrylonitrile copolymer. You can find asa in a form of resin used for molding or solid like filament film or sheet material. Acrylonitrile styrene acrylate asa geloy resin improved uv over pc abs excellent processability higher heat and impact vs.
