CAS Number: 51240-95-0
Physical form: liquid
Initiator for the (co)polymerization of ethylene, vinyl chloride and vinylidene chloride.
Ethylene Polymerization: Trigonox® 423-CS70 can be used for LDPE manufacturing in both autoclave and tube processes. Trigonox® 423-CS70 is a very reactive peroxide and can be used in combination with less reactive initiators such as tert-butyl peroxyneopentanoate (Trigonox® 25), tert-butyl peroxybenzoate (Trigonox® C) and others. The TA and Io/PE of Trigonox® 423-CS70 are expected to be similar to that of isopropylphenyl peroxyneodecanoate (Trigonox® 99). Polymerization of Vinyl Chloride: Trigonox® 423-CS70 is a highly reactive initiator. It can be used between 40°C and 65°C. It can also be used for the polymerization of vinyl chloride. Trigonox® 423-CS70 is often used in combination with less reactive initiators such as dicarbonate peroxide (e.g., Perkadox 16) or diacyl peroxides (e.g., Laurox) to improve reactor efficiency.
