A tough weather stable styrenic with an acrylic rubber phase that resists ultraviolet light, so it holds its strength, color, and surface finish through years of sun exposure. It absorbs very little water and stays serviceable to about 100°C. Aromatic and chlorinated solvents will swell or dissolve it.
