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.
Thermoplastic vulcanizate (TPV), which consists of a polyolefin phase (PP) with a dynamically cured EPDM phase, is closely dispersed in the PP matrix which gives rubber-like properties and has the advantage of thermoplastic processing techniques.
Thermoplastic polyurethane (TPU) is a block copolymer consisting of alternating sequences of hard and soft segments. Its adaptability is due to the presence of both these hard and soft segments in its chemical structure. The proportion of hard and soft segments can be manipulated to produce a wide range of hardness.
TPEE (thermoplastic polyester elastomer) is a block copolymer containing polyester hard segment and polyether soft segment.
Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class ofcopolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials withboth thermoplastic and elastomeric properties.
