EFOX® 20 S500 is a di-tert-butyl peroxide initiator suitable for use between 95°C and 185°C. It is typically used for producing low-density polyethylene (LDPE) products, providing rapid reaction initiation and curing.
EFOX® 20 S500 is an initiator from AKPA that offers enhanced reliability for the production of low-density polyethylene resins. It contains a high-purity solution of di-tert-butyl peroxide with an assay of 99.0% and an active oxygen content of 10.83%. Suitable for use in the polymerization and copolymerization of resins, this initiator can be used in both autoclave and pipe-type processes. It may also be used in the copolymerization of styrene, acrylate, or methacrylate resin solutions.
