Potassium Soap of Disproportionated Rosin DRS K 80

Disproportionated rosin (DPR) is compound of dehydroabie acid and dihydroabtice acid, the DPR is processed through catalytic reaction of gum rosin on proper temperature. In the synthetic rubber industry, DPR is used as emulsifier in the producing of various products including styrene-butadiene rubber, chloroprene rubber, acrylonitrile-butadiene rubber and acrylonitrile-butadiene-styrene rubber. Using DPR as an emulsifier, rubber product will improve in cohesion, and the endurance to heat will increase for 25%. The endurance to both abrasion and laceration of this rubber is better than ordinary styrene-butadiene rubber. The cohesion will be greatly enhanced if blended with natural rubber.

Rosin modified maleic anhydride resin is a slight yellow transparent solid, which is adducts of gum rosin and maleic anhydride through the esterification by glycerol or pentaerythritol.   

Diaminofunctional Silane Polymer Crosile® 5246 is used in adhesives, sealants and coatings to improve the adhesion of amino reactive resins to inorganic surfaces, plastic surfaces and inorganic fillers.

Amino Silane Coupling Agent Crosile® 792 A colorless or pale-yellow transparent liquid, soluble in aether, benzene. Being able to react with acetone, carbon tetrachloride, water. Boiling point 259℃.  

A comparative study of α- and γ-functional silane coupling agents in silica-filled SBR vulcanized with conventional sulfur systems shows that the effects of silanes on vulcanization kinetics and their coupling effects depend on their structure and location. Rubber reactive groups. All tested silanes containing mercapto or sulfide functional groups resulted in improvements in tensile properties and affected the cure kinetics of the systems used.

High absorption and good fluidity silicon dioxide. As carrier and anti caking agent, convert any kind of liquid into free flowing powder. Used as anti caking agent for feed additives, anti caking agent in feed, silica anti caking agent.

Chlorosulfonated Polyethylene is a kind of white or yellowish elastomer in round chip with not only the same properties as base polymer but also special properties of itself. It’s soluble in aromatic hydrocarbon and hydrochloric ether, insoluble in fatty hydrocarbon and alcohol, only swells but not soluble in ketone and ether. It has excellent ozone resistance, atmospheric ageing resistance, chemical resistance, etc., also has better physical mechanical features, heat ageing resistance, heat endurance, subzero resistance, fuel resistance, abrasion resistance and electrical insulation.  

Crosile® 69s is a mixture of Crosile® 69s silane coupling agent and precipitated silica with the same function as Crosile® 69s but easier to operate. It can improve the physical and mechanical properties of rubber and greatly strengthen tensile strenth, antitearing strenth, abrasion resistance, reduce the permanent deformation and viscosity of gross rubber, improve process property. Suitable polymers include NR, IP, SBR, BR, NBR, EPDM, etc.
