Properties Non-toxic. Relative density is 1.05. soluble in benzene, acetone, chloroform, carbon disulfide, a little soluble in petrol-hydrocarbon, insoluble in water.
Applications A kind of amine antioxidant, the property of anti-heat oxide is good. It is suitable to nature rubber and variety of synthetic rubbers except chloroprene rubber. The effecting is invisible to protect curved fatigue and ozone, usually use it with other antioxidant that can protect curved fatigue and ozone. It is widely used to manufacture tyres, rubber tuber, belts, shoes, fiber, normal industrial rubber products, also latex products. It is known as a stabilizer which used to polyisopentadiene rubber, butadiene rubber, butadiene styrene rubber. It is able to inhibit harmful metals.
Storage Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
