Usage

This product is a general antioxidant for natural rubber, diene synthetic rubber, neoprene rubber and base latex. It has good protective effect on heat, oxygen, flexion and general aging, and is slightly superior to antioxidant A. It has inhibitory effect on harmful metals, but weaker than antioxidant A. If combined with antioxidant 4010 or 4010na, the resistance to heat, oxygen, flexion cracking and ozone resistance were significantly improved.

It has no effect on the vulcanization rate of natural gum, nitrile gum and styrene-butadiene gum, but slightly delayed the vulcanization rate of neoprene gum. This product is easy to decompose in dry glue and easily dispersed in water. The solubility of this product in rubber is about 1.5%, and frost spray will not occur if the dosage does not exceed 1 phr. The product is polluting and grayish black in the sun, so it is not suitable for white or light color products. Mainly used in manufacturing tires, hose, tape, cots, rubber shoes, wire and cable insulation and other industrial products. Anti-aging agent Ding can also be used as stabilizer for post-treatment and storage of various synthetic rubber, and can be used as anti-aging agent for polyformaldehyde. This product has certain irritation to the skin.
