Application:
Nickel dibutyldithiocarbamate can be used as an antioxidant for CR, CSPR, ECO, SBR, NBR, etc. In CR, it can improve the thermal resistance of rubber, and reduce the discoloration under the sun, and it can slightly retard the vulcanization. It is a kind of thermal stabilizer in CSPR vulcanized by metal oxide. In SBR, it has good protective character to ozone, weather, aging, crazing and flexing, but it has no oxidation resistance, so it should be used together with good antioxidant. It can easily disperse in rubber and make the rubber green, but is pollution-free. Normal dosage is 1-2 phr in CR and 0.5-3 phr in SBR.
Packing: In 25kgs net paper bags lined with PVC film bag
Storage: Store in a cool, well-ventilated place. Keep away from moisture and fire
