Features of MMA
A clear colorless liquid. Slightly soluble in water and floats on water. Vapors heavier than air. Vapors irritate the eyes and respiratory system. Containers must be heavily insulated or shipped under refrigeration. An inhibitor such as hydroquinone, hydroquinone methyl ester and dimethyl t-butylphenol is added to keep the chemical from initiating polymerization. The chemical may polymerize exothermically if heated or contaminated with strong acid or base. If the polymerization takes place inside a container, the container may rupture violently. Used to make plastics.
Applications
1.Mainly used for organic glass monomer, also for making other plastics, coating
2.Methyl methacrylate is fungicide sclerotium net intermediate
3.Also used in the manufacture of other resin, plastic, adhesives, coatings, lubricants, wood infiltration agents, motor coil soaking agents, ion exchange resin, paper, polish, textile auxiliaries, leather treatment agent and insulating pouring material
