in water; miscible with most organic solvents such as acetone, ethanol,
and benzene.
Chemical Properties:
- Reactivity: Methyl
methacrylate can polymerize, especially in the presence of heat, light, or
peroxides. It is a reactive ester that can undergo various esterification
reactions.
- Flammability: Flammable
liquid with a flash point of 10°C.
Uses:
- Polymers and Resins:
Primarily used in the production of polymethyl methacrylate (PMMA) for
plastics and resins. PMMA is known for its clarity, strength, and UV
resistance, making it suitable for applications like acrylic glass
(Plexiglas), automotive parts, and coatings.
- Adhesives and Sealants: Used
in the manufacture of adhesives, sealants, and cement.
- Medical Applications:
Employed in the production of medical devices and dental materials,
including bone cement for orthopedic surgery.
- Coatings: Utilized in surface
coatings for durability and aesthetic finishes.
Safety Information:
- Hazards: Methyl methacrylate
is an irritant and can cause skin, eye, and respiratory irritation.
Prolonged exposure can lead to sensitization and allergic reactions.
- Handling: Should be handled
with appropriate protective equipment, including gloves, goggles, and
protective clothing. Ensure good ventilation or use respiratory protection
to avoid inhalation of vapors.
- Storage: Store in a cool, dry
place away from sources of ignition and polymerization catalysts.
Containers should be kept tightly closed and protected from light and
heat.
Environmental Impact:
- Biodegradability: Methyl
methacrylate is biodegradable under certain conditions.
- Ecotoxicity: It can be toxic
to aquatic life in high concentrations, and care should be taken to avoid
release into the environment.
