1. Activity, uniform particle size, dispersion, and good to promote the role of vulcanized vulcanizate Crosslink density, more thorough sulfide.
2. can better improve the stickiness of the rubber, to improve the adhesion of rubber and reinforcing materials such as wire and cord.
3. The dynamic mechanical properties, deformation of the rubber products, and less heat, abrasion, making it a good resistance to aging.
People's Republic of China standard GB / T3185-92% (m / m)
USES:
Rubber grade zinc oxide is used in radial tires, bias tires, conveyor belts, hoses, tape, rubber, latex gloves and other rubber products. Performance of their products fully comply with the requirements of the countries, the Ministry of Chemical Industry and American Standard
Storage:
Store in a cool, ventilated coffers. Keep away from fire and heat source. And oxidizer stored separately to avoid mixing reservoir. The storage area should be equipped with suitable material spill.
