Description
Methyl methacrylate (CAS 80-62-6) is a reactive acrylic monomer also known under trade names TEB 3K, Pegalan, and Acryester M. It serves as a primary building block for polymethacrylate chains and is registered under REACH with EC number 201-297-1.
In plastics and coatings manufacturing, methyl methacrylate undergoes free-radical polymerization to form PMMA, delivering optical clarity and surface hardness in sheet, rod, and cast applications. In adhesive and sealant formulations, it acts as a crosslinker, reacting with co-monomers to build network structures that control flexibility and bond strength.
Methyl methacrylate is supplied in inhibited monomer grade to prevent premature polymerization during storage and transport. It falls under REACH regulation and requires standard hazardous goods handling documentation. Packaging is typically available in drums and IBC containers, with FCC-grade material available for permitted flavoring applications.
