TRIMETHYL BORATE Resistant O-Rings and Seals
Trimethyl borate, or TMB, is a synthetic compound used in the production of agrochemical products, pharmaceuticals, and surfactants. Common uses include as an intermediate chemical in the production of agrochemical products, as a binder in pharmaceuticals, and as an emulsifier in surfactants.
Common failures of rubber when exposed to TMB include cracking and embrittlement of the rubber, discoloration, and decreased flexibility of the rubber material. Cracking and embrittlement can occur due to TMB's ability to penetrate the rubber and harden it, weakening the material. Discoloration can be caused by the chemical reacting with the rubber, resulting in a discolored surface. Finally, decreased flexibility of the rubber can occur as a result of the chemical breaking down the rubber material over time.
