Methyl Methacrylate (MMA) is an organic compound with the chemical formula C₅H₈O₂, which is mainly used as a monomer for organic glass, and is widely used in the fields of resins, plastics, and coatings.
Properties of Methyl Methacrylate (MMA)
Methyl Methacrylate (MMA), alias methyl isobutenoate or methyl methyl ester, is a colorless liquid with the following properties:
Physical Properties
MMA is a colorless, transparent liquid at room temperature and pressure with an irritating odor. Its density is 0.942 g/cm³, boiling point is about 100°C, flash point is 10°C, it is flammable and volatile.MMA has low solubility in water, but is miscible with most organic solvents, such as alcohols, ketones and esters.
Chemical Properties
MMA molecule contains a double bond and an ester group and has high reactivity. It readily undergoes free radical polymerization to produce polymethyl methacrylate (PMMA).MMA can also participate in copolymerization reactions, copolymerizing with other monomers such as styrene and acrylonitrile to form copolymers with varying properties.MMA is resistant to light, heat, and chemical reagents, but it will decompose when exposed to light or high temperatures for long periods of time.
methyl methacrylate uses
- Adhesives: MMA-based polymers provide strong bonding, heat resistance, and durability for automotive, electronics, and construction applications.
- Coatings: Its high clarity, UV resistance, and surface hardness make MMA widely used in protective and decorative coatings for metal, wood, and industrial surfaces.
- Resins: MMA is the primary monomer for producing acrylic and specialty resins used in plastics, inks, and composite materials.
Stable Quality, Wide Range of Applications
Due to its versatility, methyl methacrylate (MMA) is increasingly used in the formulation of materials with high transparency and resistance to harsh environments. Industries include automotive repair, industrial machinery, packaging, and building materials.
