Purpose

Can be used for the after-effects of reclaimed rubber of natural rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber and natural rubber Sex enhancer. This product has the advantages of excellent scorch resistance and short vulcanization time, that is, there is no danger of scorch at the operating temperature, but it has a strong promotion effect at the vulcanization temperature, especially in natural rubber, which has greater aftereffects. This product requires zinc oxide and stearic acid, and can also be activated by thiuram, dithiocarbamates, aldehydeamines, guanidine accelerators and acidic substances. This product has slight contamination and almost no discoloration. It can be used to make light-colored or bright-colored rubber products, mainly used to make tires, rubber shoes, hoses, tapes, cables and general industrial products.
