(1) Antioxidant D (PBN)/ DMT is a general-purpose anti-aging agent for natural rubber, diene synthetic rubber, neoprene rubber and base latex.

(2) Antioxidant D (PBN)/ DMT has good protection against heat, oxygen, flexing and general aging, and is slightly better than anti-aging agent A. Antioxidant D (PBN)/ DMT has an inhibitory effect on harmful metals, but it is weaker than the anti-aging agent.

(3) When used in combination with antioxidant 4010 or 4010NA, resistance to heat, oxygen, flex cracking, and ozone resistance are significantly improved.

(4) Antioxidant D (PBN)/ DMT has no effect on the vulcanization rate of natural rubber, nitrile rubber and styrene-butadiene rubber, and has a slight retardation effect on neoprene.

(5) Antioxidant D (PBN)/ DMT is easy to decompose in dry glue and is also easy to disperse in water. The solubility of Antioxidant D (PBN)/ DMT in rubber is about 1.5%, and no more than 1 part will not bloom.

(6) Antioxidant D (PBN)/ DMT is polluting and fades to grayish black in daylight, so it is not suitable for white or light colored products. Mainly used in the manufacture of industrial products such as tires, hoses, tapes, rubber rollers, rubber shoes, wire and cable insulation.

(7) The anti-aging agent can also be used as a stabilizer for post-treatment and storage of various synthetic rubbers, and can be used as a heat-resistant anti-aging agent for polyoxymethylene. Antioxidant D (PBN)/ DMT has a certain irritating effect on the skin.
