Product Details

Methyl Methacrylate CAS#80-62-6

Methyl methacrylate is an natural compound with the system CH2=C(CH3)COOCH3. This colourless liquid, the methyl ester of methacrylic acid (MAA) is a monomer produced on a giant scale for the manufacturing of poly(methyl methacrylate) (PMMA).
Methyl methacrylate is a methyl ester of methacrylic acid. It is a colourless, risky liquid with an acrid fruity odour. It has a fantastically excessive vapour strain (4 kPa at 20°C), average water solubility (15.8 g/litre), and a low log octanol/water partition coefficient (Kow = 1.38) . Methyl methacrylate is generally 99.9% pure and consists of small quantities of inhibitor to retard polymerization

Toxicity	The acute toxicity of methyl methacrylate is low. Irritation of the skin, eye, and nasal cavity has been observed in rodents and rabbits exposed to relatively high concentrations of methyl methacrylate. The chemical is a mild skin sensitizer in animals. The effect observed most frequently at lowest concentration after repeated inhalation exposure to methyl methacrylate is irritation of the nasal cavity. Effects on the kidney and liver at higher concentrations have also been reported.
IDLA	1,000 ppm

Product Usage

1.Methyl methacrylate is a risky artificial chemical that is used basically in the manufacturing of solid acrylic sheet, acrylic emulsions, and moulding and extrusion resins.
2.In the manufacture of methacrylate resins and plastics. Methyl methacrylate is transesterified into greater methacrylates such as n-butyl methacrylate or 2-ethylhexyl methacrylate.
3.Methyl methacrylate monomer is used in the manufacturing of methylmethacrylate polymers and copolymers, polymers and copolymers are additionally used in waterborne, solvent, and undissolved floor coatings, adhesives, sealants, leather-based and paper coatings, inks, flooring polishes, cloth finishes, dental prostheses, surgical bone cements, and leaded acrylic radiation shields and in the coaching of artificial fingernails and orthotic shoe inserts. Methyl methacrylate is additionally used as a beginning cloth to manufacture different esters of methacrylic acid.
4.Granules for injection and extrusion blow moulding which for their super optical clarity, weathering and scratch resistance are used in lighting, workplace gear and electronics (cell cellphone shows and hi-fi equipment), constructing and development (glazing and window frames), modern-day layout (furniture, jewelry and tableware), motors and transportation (lights and instrument panels), fitness and protection (jars and check tubes) and family home equipment (microwave oven doorways and mixer bowls).
