ASA - The Thermoplastic for Optimum UV Performance

If your product is exposed to outdoor conditions that can degrade materials over time, or cause color fading and component deterioration, consider Acrylonitrile Styrene Acrylate (ASA) as a durable alternative to PVC or ABS. ASA is a highly rigid thermoplastic that offers enhanced weatherability and outdoor performance, potentially reducing warranty claims and improving product reputation and competitiveness.

Stands up to Chemicals, Impacts and Extreme Temperatures 

In addition to outstanding resistance to UV radiation, ASA brings a host of other properties to the table - like oil, chemical and salt resistance; high strength; wear and impact resistance; and a heat distortion temperature of 25°F higher than PVC. The latter can help components resist deformation under load in hot environments. ASA does an outstanding job of retaining properties under continuous frigid conditions as well. Given the potential benefits for various outdoor applications where it is currently underutilized, it is evident why I believe this material could be highly suitable.

ASA is most commonly used and well-proven in vinyl siding for the façades of residential and commercial buildings, as well as outdoor furniture. However, the material can provide outstanding benefits in a host of other applications where unrelenting sun and environmental exposure are potential factors. These can include window and door applications; outside panels and components on boats and marine equipment; snowmobiles, jet skis and other powersports equipment; outdoor HVAC components; even components on the outsides of tractors and other agricultural and construction vehicles. 

For the triple pane window application, rigid ASA features will prevent sagging due to heavy glass weight and maintain strength and mechanical properties despite prolonged UV exposure. ASA parts feature an attractive surface finish, retaining color, gloss and durability against various environmental factors like sun, wind, rain and temperature changes. 

Benefits of a Thin Coating of ASA, Cap-Stocked Over Your Current Substrate Material

ASA may come at a higher cost compared to alternate materials. However, incorporating an ASA cap-stock (a thin layer) over traditional materials like PVC, can provide superior temperature, UV and chemical resistance benefits without the 100% ASA material costs. Depending on the application, using an ASA cap-stock can enhance product properties significantly. 

While using 100% ASA may be more suitable for certain cases; based upon performance or cost considerations, adding an ASA coating can offer a substantial performance boost at a more affordable price point.
