Physical properties, uses and characteristics of rubber-grade zinc oxide

2016-12-28

Physical properties of rubber-grade zinc oxide: white crystalline system crystals or powder, odorless, non-toxic, fine texture. Relative density 5.606, refractive index 2.008-2.009, melting point 1975. Soluble in acid, sodium hydroxide, ammonium chloride, insoluble in water, ethanol and ammonia, belonging to amphoteric oxide, absorbs carbon dioxide and water in the air to generate zinc carbonate, which is yellow, turns yellow when heated, and recovers white after cooling. It does not transmit ultraviolet light and does not turn black when exposed to hydrogen sulfide. Uses of rubber-grade zinc oxide: In the rubber industry, it is used as a vulcanization activator for natural rubber, synthetic rubber and latex, as well as a reinforcing agent and coloring agent. It can also be used to produce...

Physical properties of rubber-grade zinc oxide: white crystalline system crystals or powder, odorless, non-toxic, fine texture.

It does not transmit ultraviolet light and does not turn black when exposed to hydrogen sulfide.

Uses of rubber-grade zinc oxide: In the rubber industry, it is used as a vulcanization activator for natural rubber, synthetic rubber, and latex. It is also used as a reinforcing agent and colorant, and can be used to produce radial tires, bias tires, conveyor belts, rubber tubes, rubber tapes, rubber shoes, latex gloves and other rubber products.

Zinc oxide is an indispensable additive in the rubber and tire industry, and is also used as a vulcanization activator, reinforcing agent, and colorant for natural rubber, synthetic rubber, and latex. Nano zinc oxide used in rubber can fully exert its vulcanization promoting effect, improve the performance of rubber, and its dosage is only 30%~50% of ordinary zinc oxide.

Characteristics of rubber-grade zinc oxide: 1. High activity, uniform particle size, good dispersibility, good vulcanization promoting effect, improved crosslinking density of vulcanized rubber, and more thorough vulcanization.

2. It can better improve the material viscosity and improve the adhesion between rubber and steel wire and carcass materials such as fabrics.

3. Good dynamic mechanical properties, small deformation of rubber products, less heat generation, good wear resistance, and good aging resistance.
