DTBP is a liquid dialkyl peroxide. It is an efficient initiator for polymerization of olefins and acrylic resins,and a modification agent of PP degradation, insoluble in water, soluble in organic solvents such as toluene, acetone, styrene,etc. Freezing point lower than-30℃.
DTAP is clear liquid,it is an excellent polymerization initiator of LDPE and Acrylic resins.its main decomposition products: teramyl alcohol, isobutene, methane, ethane, butanone,etc
Dicumyl peroxide is white crystalline.Melting point of 41-42℃. Relative density of 1.082.Decomposition temperature 120-125℃ room temperature stable. Gradually become yellowish under light. insoluble in water, soluble in ethanol, ether,acetic acid, benzene and petroleum ether.
DCBP is a white to yellowish viscouspaste diacyl organic peroxide cross-linkingagent of silicone rubber with 150-400'℃ hot air without pressure.
DBPH is a low volatility, yellowish liquid, dialkyl peroxide for cross linking of elastomers (silicone rubber, EPDM, PE etc.). Mp8 ℃, relative density 0.8650, refractive index 1.4185 (28 ℃), flash point: closed/36 ℃, open/ 58 ℃,self-accelerating decomposition temperature /80℃. not soluble in water, soluble in alcohols, esters, ethers, hydrocarbons and organic solvents, has a special smell. Active oxygen Content 11.02%.
TBPIN Used for curing thermosetting resin; polymerization of acrylate and methacrylate.
CHP may be used for various polymerization reactions. It can be used in emulsion,solution and bulk polymerizations.In emulsion processes,it may be activated by organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature or lower.
TAPPI is mainly used as initiator for ethylene polymerization, and also suitable for polymerization of vinyl chloride, vinyl acetate, methacrylate, acrylonitrile and other olefins. It is usually combined with other peroxides to achieve a wider range of polymerization temperature to improve the reaction efficiency.
Used as initiator of polyethylene, polyvinyl chloride, etc. it is a kind of high efficiency low temperature initiator.It can be used as an initiator for suspension polymerization of vinyl chloride monomer and for free radical polymerization of other monomers.
TAPEH,Colorless transparent oily liquid, insoluble in water, soluble in most organic solvents.
BPO 75% is a wet granular of diacyl peroxide, used as initiator of polymerization in expandable polystyrene(EPS),acrylic resins and curing agent for unsaturated polyester resin and elastomers.
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.
BPO 50% powder is a fine, free-flowing, non-caking granular powder consisting of 50% dibenzoyl peroxide, phthalate 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.
