Applications:
1. rubber antioxidant, than the harsh conditions can inhibit the oxidation, heat aging, weather aging and fatigue aging, as compared with ordinary antioxidant effect of a higher RD.
2. The catalytic oxidation of metals have a stronger inhibitory effect.
3. This product does not spray cream in a small number of light-colored products can be used.
4. The higher molecular weight materials, the proliferation of small losses, to maintain the protective properties of longer applicable to high temperature of the rubber products.
5. HP-RD, compared with the general RD has the following advantages:
a. 234 of the polymer materials (effective aging group) high.
b. The plastic does not affect the solution of natural rubber (general RD with plastic two-aniline solution will affect the role of agent).
c. does not affect the sulfide (RD with ordinary two-aniline scorch time will be shortened, causing the early sulfide).
d. time to extend the rubber and the surface parking will not change the Blue (General Xiao Yi RD molecular changes to move out of the blue).
6. In the cross-linked PE cable application advantages:
a. on the cross-linking agent (peroxide) interfere small.
b. Even in the mixture of silane solution was transparent, that the best compatibility.
c. reduce the products exposed to sunlight and air of the discoloration.
Usage: Mixed join with drugs.
Usage: the general amount of 0.5-2 PHR, up to 3 PHR.
Description:
1. Applicable to natural rubber, styrene-butadiene rubber, acrylonitrile-butadiene rubber, butadiene rubber, chloroprene rubber, EPDM, IR, etc., and latex.
2. This product is suitable for manufacture of cables, wires, industrial products and a bike tire.
3. In the dynamic conditions of the use of rubber products, such as the tire tread and the conveyor belt and so on, may be HP-RD and the antioxidant or antioxidant 4020 and MB.
