Chemical name: tert-Butyl Peroxybenzoate
CAS number: 614-45-9
Description and features
Enox TBPB (tert-Butyl Peroxybenzoate) is yellowish liquid which has C11H14O3 as chemical formula. It is a low volatility, high purity, aromatic peroxyester. which is effective as medium temperature initiator for polymerization of a broad spectrum of monomers, per example acrylics, ethylene and styrene. It is also used to cure (copolymerization) unsaturated polyester resins at elevated temperatures. Further it is used as catalyst for crosslinking synthetic rubbers like EPR, EPDM and NBR.
