Toxicity and protection

Methyl methacrylate is less toxic and less toxic than acrylate or acetone. The oral lethal dose (LD50) of rats was 9400 mg/kg, and the maximum allowable concentration in the workplace was 100 p.pm (410 mg/m3).

The toxicity test of methyl methacrylate on human body shows only a very small amount of red rash. The methyl methacrylate polymer is completely irritating and toxic.

use:

Methyl methacrylate is a raw material monomer for plexiglass and one of the main functional monomers for the manufacture of other resins, plastics, coatings, adhesives and lubricants. Methyl methacrylate can also be used in the manufacture of penetrants, polishes, auxiliaries and insulating materials.

Packaging and storage

This product is packed in galvanized iron drums, 180kg per barrel and marked with a dangerous goods mark. This product is added with 100 ppm or less of p-hydroxyanisole as a polymerization inhibitor. If required by the user, no inhibitor can be added, but the responsibility is the responsibility of the user. Storage and transportation should prevent impact, keep away from fire and prevent sun exposure.
