Esperox 28 Tertiary-butyl peroxy 2-ethyl hexanoate 3006-82-4 Crompton Crosslinking / Coupling / Curing Agents >> Peroxides / Persalts / Hydroperoxides Acrylics/ Acrylates Polyolefins (PE, PP…) ESPEROX Ò 28 tertiary-Butyl Peroxy 2-Ethyl Hexanoate Esperox Ò 28 is a branched chain, aliphatic, liquid monoperoxyester (tertiary-butyl peroxy 2-ethyl hexanoate). It is a medium temperature peroxyester, with application as an initiator for vinyl monomer polymerizations such as styrene, ethylene, and acrylates. The reactivity and absence of aromatic groups make Esperox 28 an excellent replacement for benzoyl peroxide. Branched chain, aliphatic, liquid medium temperature monoperoxyester. Used as an initiator for vinyl monomer polymerizations such as styrene, ethylene, and acrylates.
