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

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.
 Curing agent for pre-promoted polyester and vinyl ester resins under room temperature.
 White and red (brick red) colors can be available which 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.
