Acrylonitrile Styrene Acrylate

ASA

Similar to ABS, ASA has great impact with the added benefit of increased weathering and UV resistance. This is important for applications such as automotive, where long-term, outdoor performance is valued. Low shrink makes this easy to design for injection molding. Can be mixed with other resins to modify properties.
