About Methyl Methacrylate

Methyl Methacrylate is a clear, colorless liquid with a sharp, fruity odor and high volatility. It is a methyl ester of methacrylic acid and is primarily used as a monomer in polymer production. MMA polymerizes readily and forms transparent, weather-resistant plastics. It is an essential ingredient in lightweight and durable materials used across various industries.

Applications / Uses

MMA is widely used for producing polymers and copolymers:

  • Plastics: The main monomer in the production of PMMA (acrylic glass), used in displays, lenses, and signs.
  • Adhesives & Sealants: Provides strength and clarity in structural adhesives and assembly bonding systems.
  • Coatings: Used in paints, varnishes, and protective coatings to enhance weather and UV resistance.
  • Automotive: Found in exterior panels, light covers, and coatings due to its durability and light weight.
  • Construction: Used in reactive resins for flooring, road markings, and waterproofing membranes.
  • Medical Devices: Applied in bone cements and dental applications because of its biocompatibility and transparency.

Storage & Handling

  • Store in tightly sealed, inhibitor-stabilized containers in a cool, well-ventilated place.
  • Protect from heat, sunlight, and sources of ignition — MMA is highly flammable and can polymerize.
  • Wear appropriate PPE including gloves, goggles, and chemical-resistant clothing.
  • Provide adequate ventilation or use respiratory protection to avoid vapor inhalation.
