Specifications
Zinc oxide 99.7%, 99.5%,99%
Process: direct,indirect zinc oxide
Producation:1000mt/month
Ceritificate: ISO90012000
zinc oxide 99.7%Physical and chemical properties:
density:5.606; melting point: 1975°
Direct method zinc oxide99.7% which belongs to gender-oxide dissolves in Acid, alkali solution but not in water or ethanol.
Direct method zinc oxide turns yellow at high enough temperature and restores white
zinc oxide 99.7%Characteristics and functions:
1.It has strong activity, uniform particle size and strong dispersion. It plays a good rule in the promotion of vulcanization. It can increase the crosslink density of vulcanized rubber and vulcanizes more completely.
2. It can better improve the rubber viscosity and improve the adhesion between rubber and skeleton materials such as steel wires and curtain fabric.
3. Rubber has good Dynamic performance, small deformation, less heat production, nice wearability and good resistance to aging
zinc oxide 99.7%Application:
Rubber zinc oxide is used in radial tires, bias tires, conveyor belts, rubber hoses, rubber belts, rubber shoes, latex gloves and other rubber products manufacturing. Our products’ performance is in full compliance with the requirements of the state, ministry of chemical industry and U.S. ASTM standards.
Packaging and Transport:
1. Packed in woven bag lined with plastic bag.
2. Standard weight: 25kg
3. We can also have packed as per users’ instruction.
4. Pay attention to keep away from moisture in transportation and storage process.
