Application:
l Free radical polymerization initiator and cross-linking agent in a wide variety of applications.
l 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.
l 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:
l Polymerization initiator and curing agent for monomeric vinyl, acrylic, styrene and unsaturated polyester/vinyl ester resins.
l curing road marking paint and for acrylate based resins.
l Curing agent for pre-promoted polyester and vinyl ester resins under room temperature.
l White and red (brick red) colors can be available which serve as a visual guide to ensure uniform dispersion in the patching compound.
l 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.<span style="box-sizing: content-box; margi
