From the chemical structure, acrylonitrile units provide hardness, chemical resistance and thermal stability; styrene units give good processability, gloss and transparency; acrylate units greatly enhance the weather resistance of the material, making it resistant to ultraviolet (UV) radiation, oxidation and various factors in the outdoor environment.
ASA plastics are usually opaque materials, and the color can be adjusted during the synthesis process as needed. Its density is generally between 1.05-1.10g/cm³, and it has good mechanical properties, including high strength and toughness, and its impact resistance is better than ABS plastic. Its thermal stability is good, in the normal use of temperature range will not easily deformation. And due to the presence of acrylate, it has excellent weather resistance, long-term exposure to the outdoor environment, the color and physical properties of the retention is high.
