Overview | Compared with tert-butyl benzoate peroxide and di-tert-butyl peroxide, the half-life temperature of tert-butyl peroxy-2-ethylhexanoate for 1 second is 185 ℃, which is a high-efficiency and fast initiator, which can quickly initiate polymerization at a lower temperature and increase the production capacity of the polymerization reactor; tert-butyl peroxidation (2-ethylhexanoic acid) initiates polymerization at a lower temperature, during the polymerization process, the reaction is exothermic and easy to control. |
characteristics | the free radical decomposed by tert-butyl peroxidation (2-ethylhexanoic acid) does not contain benzene ring, which will not pollute the polyethylene resin in the process of initiating the polymerization of ethylene monomer, and the resin quality is excellent. |
Application | Peroxidation (2-ethylhexanoic acid) tert-butyl ester (initiator OT) is an organic peroxide initiator, used as vinyl acetate, The polymerization initiator of all vinyl monomers such as vinyl chloride, methacrylic acid, styrene, ethylene, etc.; it can also be used as a heating molding curing catalyst for unsaturated polyester resin. |
use | used as initiator for polymerization of ethylene, methacrylate and propylene monomers mainly used as polymerization initiator for acrylic resins, vinyl acetate resins, methyl methacrylate, etc., as well as crosslinking agents and polymerization initiators for other unsaturated polyesters. |
