Nouryon Trigonox C-C75 Polymer tert-Butyl peroxybenzoate
Categories: Other Engineering Material

Material Notes: Efficient initiator (75% active ingredient in odorless mineral spirits) for the production of Low Density Polyethylene (LDPE). It is used for both tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range.

CAS number: 614-45-9

EINECS/ELINCS No: 210-382-2

Applications: Polymerization of styrene Trigonox C-C75 may be used for the (co)polymerization of styrene in the temperature range of 100-140°C. In practice, combinations of two or more peroxides with diverging activities are used to reduce the residual monomer content in the final polymer and to increase reactor efficiency. In suspension polymerization processes Trigonox C-C75 is often used for reduction of residual styrene content during the final polymerization stage.
