Methyl Methacrylate Monomer
Description and uses
Some examples on the use of MMA:
- acrylic sheet for architectural and automotive glazing, advertising signs, glazing and skylights, interior and exterior lighting, decorative panels
- acrylic and modified molding compound for lighting, optical lenses, packaging, medical devices, impact modifiers
- acrylic lattices for paints, floor polishes, waxes, adhesives, sizing
- acrylic solutions for lacquers and thermosetting automotive and appliance enamels
- acrylic resins
MMA is also used to impregnate wood and modify polyester resins to improve weather ability, gloss and hardness. MMA is also used for acrylic fibers, oil additives, the impregnation of concrete to make it water-repellent and also has uses in the fields of medicine and dentistry to make prosthetic devices and as a ceramic filler or cement.
MMA is a reactive monomer and can readily be polymerized with itself or with other monomers to form thermoplastic and thermosetting polymers. It's polymers have a wide range of properties and applications. Acrylic polymers can be produced by bulk, solution, emulsion, or suspension polymerization in the form of sheets, films, foams, molding pellets, powders, lattices, and solutions.
MMA is sometimes used in the beauty industry as an ingredient for artificial nails. Experts point out that, for various reasons, MMA is unsuitable for this application and a much better alternative Ethyl Methacrylate (EMA) is available.
