2. Applications:
MMA is an important organic chemical raw material primarily used to produce acrylic glass (polymethyl methacrylate, PMMA). It is also used in the manufacturing of other resins, plastics, coatings, adhesives, lubricants, impregnants for wood and cork, impregnants for motor coils, paper gloss agents, printing and dyeing auxiliaries, and insulating potting materials. Its main downstream product, acrylic glass, is a significant thermoplastic developed early on. It is known for its beautiful appearance, excellent light transmittance, chemical stability, weather resistance, ease of dyeing, and ease of processing. These properties make it widely used in the automotive, construction, sanitary ware, and public engineering industries. Additionally, MMA is used in the production of coatings, PVC resin modification and processing aids, adhesives, lubricants, the second monomer for acrylic fibers, and textile sizing agents.
3. Precautions for Use:
MMA is highly flammable and can form explosive mixtures with air. It is easily ignited by open flames, high temperatures, and oxidizing agents. Combustion produces irritating fumes. It reacts chemically with oxidizing agents and acids. Long-term storage is not advisable to prevent polymerization reactions.
