CAS No. 1550-44-3 is the scientific name for the organic compound known as methyl methacrylate (MMA). MMA is a colourless liquid with a slightly pungent smell and is widely used in the plastics industry.
Methyl methacrylate is an ester of methacrylic acid. It is used in a variety of polymer applications: It is a main monomer used in the production of polymethyl methacrylate (PMMA) and its copolymers, poly(methyl methacrylate-co-styrene) (PMMAS). PMMA is a type of plastic used in a variety of products, including medical implants, dental prostheses, automotive parts, and window glazing. MMA is also used to produce water-resistant adhesive and sealants, as well as coatings and inks.
Methyl methacrylate is also used in the manufacture of artificial nails. MMA is mixed with a polymerizing agent and applied as a liquid to the natural nail. The solution sets in a few minutes and hardens to a durable and glossy finish.
Methyl methacrylate is also used in the production of rubber products. It is added to rubber compounds to improve the properties of the rubber, such as its tensile strength, flexibility and heat resistance.
Methyl methacrylate is an irritant and causes skin and eye irritation. Inhalation of fumes can cause respiratory irritation and, in some cases, pulmonary edema. It can also enter the body through ingestion, so proper safety precautions should be taken when working with this compound.
As with any chemical, proper storage is essential. Methyl methacrylate should be kept away from direct sunlight and stored in a cool, well-ventilated area. The container should be labeled with the appropriate safety information and the CAS number.
Methyl methacrylate is a versatile compound with many uses in the plastics industry. It is important to be aware of the potential hazards associated with this compound, and to take the necessary safety precautions when working with it.
