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

Use

Methyl methacrylate (MMA) is a monomer that's also known as methacrylic acid, methyl ester. A key building block for acrylic-based polymers, MMA has applications that include safety glazing, exterior paints, vinyl impact modifiers, adhesives, illuminated light displays, and more.
