The patented (U.S. Patent No. 5,334,326) benzoate plasticizer diluentsystem provides product formulations that can be readily dissolved in resins and monomers. Theseproducts are less hazardous and easier to use than technical or dry forms of dibenzoyl peroxideprovided the plasticizer and water content are not objectionable. Additional benefits of the benzoateplasticizer system include better resistance to the dispersion of heat degradation and the eliminationof phthalate ester plasticizers.

These paste productshave 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 inplasticizer dissolves more readily in resins and eliminates the hazardous practice ofdissolving dry dibenzoyl peroxide in styrene, acetone, or other volatile solvents. |
