Description and features
Enox DTBP (Di-tert-butyl peroxide) is a transparent liquid with the chemical formula C8H18O2. This dialkyl peroxide serves as an initiator for the production of Low Density Polyethylene (LDPE). Furthermore, it finds application in the polymerization and copolymerization of styrene, olefins, and acrylic resins. Additionally, it acts as a modification agent for polypropylene degradation, enhancing the material’s properties.
Di-tert-butyl peroxide is also known as DTBP, peroxide bis(1,1-dimethylethyl) and tert-Butyl peroxide.
