Carbon Black Dispersant for Rubber Compound

Dispersant of carbon black and other fillers in NR, SBR, CSM, EPM, EPDM and NBR. It decreases the Mooney viscosity of compounds, shortens compounding time and decrease energy cost.

Product Details


Carbon black dispersant for rubber compound FNS-22B is blend of active filler, fatty acid esters and polar hydrocarbons, which improves the dispersion and surface properties of inorganic fillers such as carbon black. With it outstanding lubricant effect, FNS 22B decreases the Mooney viscosity of compounds, shortens compounding time and decrease energy cost. It improves the demouling property and the extrudability of compound and provides higher injection speed and volume by injection molding. The scorch properties, vulcanization properties of the compound and the physical properties of the vulcanizates are not affected by FNS-22B.

Application fields:

Dispersant of carbon black and other fillers in NR, SBR, CSM, EPM, EPDM and NBR


1. FNS-22B should be added together with the fillers at the beginning of the mixing cycle.
