t-Butyl peracetate

T-Butyl peracetate (CAS 107-71-1) is an organic peroxide supplied as a clear solution, commercially available under trade names including Luperox 7M75, Lupersol 70, Kayabutyl A, and Perbutyl A. It carries no E-code designation and is classified under the Oxidizers and Peroxides category.

In plastics and polymer processing, t-butyl peracetate functions as a free-radical initiator, decomposing thermally to generate reactive radicals that drive chain-growth polymerization of vinyl and acrylic monomers. In rubber and tire manufacturing, those same radicals create covalent crosslinks between polymer chains, improving mechanical strength and heat resistance of the cured compound.

This product is supplied as a stabilized solution and falls under REACH regulation, requiring an up-to-date Safety Data Sheet for EU procurement. It is classified under HS code 29159000 for customs purposes. Buyers should confirm concentration grade and packaging format directly, as peroxide solutions are subject to transport quantity restrictions under ADR.
