Di-tert-amyl peroxide Chemical Properties,Usage,Production

Description

Di-tert-amyl peroxide (DTAP) is a slightly yellowish, mobile liquid. This liquid dialkyl peroxide is used as an initiator (radical source) in the polymerisation of monomers, like e.g. ethylene, styrene, and (meth)acrylates.

Chemical Properties

Colorless to light yellow liquid

Uses

Di-tert-amyl peroxide is commonly used as a radical initiator to induce polymerisation (free radical polymerisation process) for the manufacture of plastic (polypropylene visbreaking, acrylicresins, LDPE/EVA), and as cross-linking agent for the production of resins (resin hardener).
