CAS 80-62-6 Methyl methacrylate MMA monomer is widely used in the production of acrylic plastics, coatings, and adhesives. Buyers and users frequently ask: Is methyl methacrylate monomer safe to use? Methyl methacrylate (MMA) monomers are generally considered unsuitable for direct, prolonged skin contact or inhalation. Appropriate safety precautions are required for the safe use of MMA in industrial and commercial applications.
What Is Methyl Methacrylate (CAS 80-62-6)?
Methyl Methacrylate (MMA, CAS 80-62-6) is a colorless, volatile, and flammable liquid with a sharp, fruity odor, predominantly used to produce poly(methyl methacrylate) (PMMA) acrylic plastics and resins. It serves as a raw material for coatings, adhesives, dental cements, and orthopedic bone cements.
- Synonyms include: methyl 2-methylprop-2-enoate and methacrylic acid methyl ester.

Despite its risks, MMA remains an important industrial chemical for the following reasons:
- Its toxicity is moderate (not highly toxic).
- The risks are well understood and manageable.
- It is an essential raw material for the production of PMMA (acrylic plastic).
- It has a long history of safe industrial applications guided by relevant regulations.
