ASA

Acrylonitrile styrene acrylic ester (ASA) is an impact-resistant terpolymer. It has similar properties to ABS, but is more weather-resistant.
During processing, additives suitable for the respective application are incorporated into the plastic matrix. These include, in particular, UV stabilizers, antioxidants, and lubricants.

Characteristic properties:
ASA creates high-quality, glossy, and scratch-resistant surfaces. It can also be made transparent. Matte surfaces can be achieved by adding matting agents or creating larger acrylic ester phases.
The excellent chemical resistance is due to the higher polarity of the acrylic ester component compared to the polybutadiene component in ABS. ASA exhibits very good resistance to aqueous media, including diluted acids/alkalis and washing solutions, and good resistance to oils/fats, alcohols, and aliphatic hydrocarbons.

Areas of application:
ASA is used primarily for weather-resistant outdoor components, as well as for electrical devices subject to high temperatures, such as coffee machines or vacuum cleaner housings. ASA has also proven its worth over many years in the sports and leisure sector, as well as for automotive exterior components.
