DICUMYL PEROXIDE

March 25, 2016

Dicumyl Peroxide is an organic dialkyl peroxide commonly used for cross-linking/curing of elastomers and plastomers, as well as being used as a polymerization initiator for polystyrene and as a curing agent for unsaturated polyesters.

As a replacement for sulfur, it is the curing agent most commonly used in the most diverse rubber industries; when there is no need to produce odorless artifacts, for having a good cure speed and mainly low cost when compared to other types of organic peroxides.

Characteristics of conventional dicumyl peroxide

Main characteristics:

Good cross-linking/curing speed;
High cross-linking/curing yield;
Characteristic odor in the product;
Good safety to pre-cross-linking/curing;
Maximum mixing temperature: 135ºC;
Ideal cross-linking temperature: 179ºC;
Stable peroxide.
