Function: natural rubber, isoprene rubber, styrene butadiene rubber, butadiene rubber, nitrile rubber and latex antioxidants, have moderate protection against oxygen aging, weathering and static aging, and can also effectively protect copper And the adverse effects caused by sulfur in the vulcanization of the product. This product is weak in single use, and can be used in combination with other anti-aging agents to obtain significant synergistic effects, and the protective efficiency is significantly increased. In the sulfur-free sulfide amine with higher content of promoter TMTD, the protection of steam is better when adding this product. If it is combined with anti-aging agent AP, the anti-heating air aging performance can be greatly improved. In the low-sulfur or sulfur-free accelerator TMTD vulcanized nitrile rubber, when the product is used together with the antioxidant AP, the product can also obtain good heat-resistant oil and other heat medium properties. It can reduce the blackening of the conductor when used in wire and cable.

In the neoprene rubber, this product has no anti-aging effect, but can promote vulcanization, accelerate the start of vulcanization, and improve the tear resistance of vulcanized rubber.

This product is easy to decompose in water. In addition to the anti-aging effect of natural rubber latex, it also has a heat-sensing effect. It can be used as an auxiliary heat-sensitive agent for foam latex rubber to reduce the amount of heat-sensitive agent. Compared with the accelerator MZ, the heat-sensitive effect is stronger, and the obtained foam structure is more uniform.
