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.

C9 hydrogenated hydrocarbon liquidResin  is a kind of ColorlessTransparent Liquid

White  granular form, Precipitated Silica White Granular Silica can be dissolved by NaOH,HF. Other kinds of acid, water and solvents can not dissolve the product.

Organosilanes containing sulfur in rubber are a type of organosilicon compound, which contain both sulfur and silicon elements in their molecules, typically with a structure similar to that of silanes. These compounds can be used as adhesives, lubricants, antioxidants, and anti-corrosion agents.

Felcosil-185 rubber grade precipitated silica is an ultrafine nano fine chemical product, which can be divided into hydrophilic type and hydrophobic type according to the surface treatment. The appearance is a white powder.

Crosile® 171 Vinyltrimethoxysilane is a silane coupling agent with a Vinyl and hydroxyl groups that can be used to enhance the wettability and improve the superhydrophobic characteristics of different composites.  

Felcosil-779: low-dust, 10–14 µm particles with 130–160 m²/g surface area deliver high reinforcement for stronger, clearer, heat-resistant HTV silicone rubber.

Precipitated silica, also called ‘white carbon black, is an amorphous form of silica (silicon dioxide, SiO2); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts.
