Methyl Methacrylate (MMA)

Methyl Methacrylate, with the chemical formula CH₂=C(CH₃)COOCH₃, is the most important acrylic ester monomer. It appears as a colorless transparent liquid with a characteristic pungent odor. It is the primary raw material for producing polymethyl methacrylate (PMMA, acrylic glass), offering excellent optical properties, weather resistance and mechanical strength. This product is widely used in plastics, coatings, adhesives and other fields.
