Type 1, BPO 75% water –wet granules
Brief Introduction：
BPO75% is a free flowing granular form of water damped diacyl peroxide, used as
initiator of polymerization in styrene, acrylic resins; and curing agent for
unsaturated resin and elastomers.
Melt point:103-106°C(decompose)slightly soluble in water, ethanol, soluble in
aether, acetone, chloroform and benzene.

10hr,Half Life Temp.…………73℃
1hr,Half Life Temp. …………92℃
1min,Half Life Temp. ………131℃
Specification：
Dibenzoyl Peroxide | 74 – 76% |
Water | 23-26% |
Assay (as dry dibenzoyl peroxide) | 99%min |
Active oxygen (wet basis) | 4.9-5.1% |
Form | free flowing granular |

Application:
Free radical polymerization initiator and cross-linking agent in a wide variety of applications.
An effective initiator in the polymerization and co-polymerization of numerous vinyl monomers which include styrene, methyl methacrylate, acrylic esters, acrylonitrile, vinyl acetate, vinyl chloride, and ethylene.
An excellent ambient temperature initiator for unsaturated polyester resins.
Type 2, BPO 50% paste
Brief Introduction：
BPO 50% paste is a fine dispersion of dibenzoyl peroxide in a smooth, non-separating fire resistant creamy paste form, which can be easily dissolved in resins and monomers. This product is less hazardous and easier to use than technical or dry forms of dibenzoyl peroxide. Slightly soluble in alcohols, petroleum solvents, insoluble in chlorinated solvents
Specification：
Dibenzoyl Peroxide | 49%-51% |
Color | White or Red |
Form | Thixotropic Cream |
Density(20 0C) | 1155kg/m3 |
Active oxygen | 3.3% |
Recommended storage temperature | 10-25°C |
Application:
Polymerization initiator and curing agent for monomeric vinyl, acrylic, styrene and unsaturated polyester/vinyl ester resins.
Curingagent for pre-promoted polyester and vinyl ester resins under room temperature.
White and red (brick red) colors can be availablewhich serve as a visual guide to ensure uniform dispersion in the patching compound.
Initiators for two-part adhesive systems based on polyester or methacrylate resins.
Type 3, BPO 50% Powder
Brief Introduction：
BPO 50% powder is a fine, free-flowing, non-caking granular powder consisting of 50% dibenzoyl peroxide, pathalate ester plasticizer and standardized with silica, which can be easily and fast dispersed and dissolved in unsaturated polyester and acrylic resins. Even at a very low temperature a good cure can be available. Dissoluble in alcohol , esters , ethers , olefins and organic solvents. Insoluble in water.
Specification：
Assay | 48.0% - 51.0% |
Water Content | ≤1.0% |
Appearance | white free flowing powder |
Acidity ( as C5H5COOH ) | ≤0.5% |
Cl | ≤0.4% |
Inorg + organic hydrolysable chloride | ≤0.5% |
Application:
Cure initiator for unsaturated polyester resins and acrylic resins. As it is easy to handle, easy to disperse and dissolves very quickly in unsaturated polyester resins and (meth)acrylic resins, for example, for curing road marking paint and for acrylate based resins.
Package and Storage：
20kg or 25kg, net, inner PE bag with outer paper
carton/drum.
Below 30℃ stored under shadow, good
air circulation. Keep in original containers hold the water content.
