Product Details


FN-TOP3 is a functional processing aid that combines a variety of refined products with polar groups and non-polar groups, combined with other functional additives to improve the appearance of rubber and tires. This product has the function of promoting the precipitation of unstable migration substances, and the unstable precipitates are sprayed out by the solubility control in the vulcanization process. The active materials in the other brighteners are combined with the residues to make them stably dissolve in the rubber system and improve the appearance of the rubber products.This product can improve the surface finish of the released product, beautify the appearance, reduce the defect rate of the product, and can replace the use of the release agent. At the same time, it can improve the service life of the mold and prolong the mold clearing time, which can significantly improve the aesthetics of the rubber product. FN-TOP3 also has the function of improving the oxidation resistance and crack resistance of the product, and has the function of increasing the solubility of the additive in the rubber. 

Application fields: 

FN-TOP3 is suitable for tire tread rubber, sidewall rubber, sub-mouth rubber and other rubber molded products to improve the appearance of the product. 


1. It is recommended to add FN-TOP3 in the front stage of mixing to exert its dispersion and lubrication to promote the dispersion of rubber and carbon black and inorganic filler. 2. The recommended amount is 0.1-2phr according to raw rubber. This product has a slight effect on physical properties when using more than 2 phr. It is recommended to verify the experiment before use.
