The positive flame-retardant super weather-resistant ASA film is modified with ASA imported from Taiwan and flame retardants. It has excellent mechanical properties, weather resistance, aging resistance, high heat resistance, and stable color. It can not only resist ultraviolet radiation. Degradation, aging, fading, and at the same time, it has a strong guarantee for oxidation in the atmosphere, decomposition or discoloration caused by high temperature during processing, which greatly improves the anti-aging and weather resistance of the material.
