Although no two Methyl methacrylate loading solutions will be identical, the product itself determines much of the critical design criteria that will ensure that optimum safety and productivity can work together in harmony.

What is Methyl methacrylate or MMA? Methyl methacrylate is a flammable, colorless liquid with a strong odor. It’s used as a chemical intermediate in the manufacture of adhesives, automotive coatings, and sealants. It can also be found in dental materials such as crowns, fillings, and veneers, as well as enamel resins and lacquers.

In the United States, MMA is typically a “tight-fill” (closed-loop) loading operation and is loaded into rail cars via chemical hoses or 3” stainless steel loading arms. Methyl methacrylate, if not handled properly can cause serious injuries and Personal Protective Equipment (PPE) is required. Additionally, because operators are on top of the vehicles during the loading process, fall prevention is essential, not only for safety but increases throughput.

Methyl methacrylate is typically shipped in DOT-115 insulated tank cars with safety valves that meet the DOT specification for the transportation of MMA and other similar commodities. The rails cars themselves are ~ 9′ outside diameter with an overall length of ~45’ to 60′, with a 6’ x 6’ center opening or off-set opening crash box.
