FAQ

Is methyl methacrylate flammable?+

Yes. methyl methacrylate (CAS 80-62-6) carries the GHS02 flame pictogram. Keep it away from ignition sources, use non-sparking tools, and ground metal containers when transferring liquid.

What PPE should I wear when handling methyl methacrylate?+

Safety glasses with side shields and nitrile gloves are the baseline. Work inside a fume hood or use a suitable respirator. Check SDS section 8 for material-specific breakthrough times.

How should methyl methacrylate be stored?+

Store methyl methacrylate (CAS 80-62-6) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials. Use a flammable-liquid cabinet and keep away from oxidizers and heat.

Is methyl methacrylate dangerous for the environment?+

No specific environmental pictogram (GHS09) is listed in our records for methyl methacrylate, but any chemical waste should be handled through your site's hazardous-waste procedure, not poured down the drain.

Where can I find the official Safety Data Sheet for methyl methacrylate?+

Official, up-to-date SDS documents are published by each manufacturer (Sigma-Aldrich, Merck, Thermo Fisher, VWR, Carl Roth, etc.) and by regulators such as ECHA and NIOSH. This page is an educational summary and does not replace the manufacturer's SDS.
