BENOX B-50 & B-55
Dibenzoyl Peroxide Paste
DEscriptION
Benox B-50 & B-55 are fine dispersions of dibenzoyl peroxide in a smooth, non-separating fire
resistant creamy paste form. The patented (U.S. Patent No. 5,334,326) benzoate plasticizer diluent
system provides product formulations that can be readily dissolved in resins and monomers. These
products are less hazardous and easier to use than technical or dry forms of dibenzoyl peroxide
provided the plasticizer and water content are not objectionable. Additional benefits of the benzoate
plasticizer system include better resistance to the dispersion of heat degradation and the elimination
of phthalate ester plasticizers.

APPLICATIONS
Benox B-50 & B-55 are principally used as polymerization initiators and curing agents for
monomeric vinyl, acrylic, styrene and unsaturated polyester/vinyl ester resins, and copolymers of
these resins, provided the plasticizer and water content can be tolerated. These paste products
have advantages over dry, granular products, and include:
1. Marked reduction of hazards involved in handling and storage.
2. The homogeneous dispersion of extremely fine particles of dibenzoyl peroxide in
plasticizer dissolves more readily in resins and eliminates the hazardous practice of
dissolving dry dibenzoyl peroxide in styrene, acetone, or other volatile solvents.
