Acrylonitrile Ethylene Styrene (AES) is a terpolymer made of the three monomers acrylonitrile, ethylene and styrene. It has good weather resistance, high heat resistance, high impact resistance, low coefficient of friction, high flow, moderate impact resistance and high rigidity. Also, AES can be flame retardant. Some uses include automotive interior and exterior parts such as trim, household goods and electrical parts
