Description
Trimethyl trimellitate (CAS 2459-10-1), also known as TMTM or methyl trimellitate, is the trimethyl ester of trimellitic acid, carrying the molecular formula C12H12O6. It holds no assigned E-code and is catalogued under EC 219-547-3. It is commercially referenced under identifiers including TIMTEC-BB SBB007965.
In plastics and polymer processing, TMTM functions as a plasticizer by intercalating between polymer chains to reduce intermolecular forces, improving flexibility and processability in PVC and related compounds. In lubricant formulations, it serves as a synthetic ester base or carrier fluid, offering thermal stability under metalworking and automotive operating conditions.
Trimethyl trimellitate is supplied as a technical-grade material and falls under REACH regulation (EC 1907/2006), requiring compliant safety documentation for European trade. It is classified under HS code 29173990. Packaging formats typically follow standard bulk liquid arrangements; buyers should confirm grade specifications and SDS availability prior to procurement.
