Product Description
Methyl methacrylate (MMA) is a colorless, volatile liquid with a pungent odor, featuring the chemical formula C₅H₈O₂. Possessing high reactivity, it is primarily used in polymerization reactions to produce acrylic glass (PMMA). Its molecular structure contains unsaturated double bonds and ester groups, making it a crucial chemical monomer with extensive industrial applications.
As a key chemical feedstock, methyl methacrylate is primarily used to produce the transparent polymer poly(methyl methacrylate) (PMMA, also known as acrylic glass). It also finds applications in coatings, adhesives, plastic alloys, and other fields. Its polymerization products exhibit excellent optical transparency, weather resistance, and mechanical properties. Furthermore, it is utilized in medical devices, electronics, textiles, and other industries, making it an indispensable basic chemical material in modern industrial processes.
