Product Description

Product Description

 

Zinc oxide is an inorganic compound with the chemical formula ZnO. It is a form of zinc oxide, in which Zn exists in the +2 form and O exists in the -2 form.Zinc oxide crystals have three structures: hexagonal wurtzite structure, cubic sphalerite structure, and the rare sodium chloride octahedral structure. The wurtzite structure is the most stable of the three and is therefore the most common. The cubic sphalerite structure can be obtained by gradually generating zinc oxide on the surface. In both crystals, each zinc or oxygen atom forms a regular tetrahedral structure with its neighboring atoms. The octahedral structure has only been observed under high pressure conditions of 10 billion Pascals.

Application
Rubber industry
In the rubber or cable industry, it is used as a vulcanizing activator, reinforcing agent and colorant for natural rubber, synthetic rubber and latex to make the rubber have good corrosion resistance, tear resistance and elasticity. It is a colorant and filler for white glue and a vulcanizing agent in chloroprene rubber. Those with fine particles (particle size of about 0.1μm) can be used as a light stabilizer for plastics such as polyolefins or polyvinyl chloride. The thermal conductivity of typical pure silicone rubber is relatively low; the thermal conductivity of silicone rubber can be improved by adding ZnO thermal conductive powder while maintaining its high electrical resistance. The addition of nanoscale fillers can achieve high thermal conductivity even at relatively low filling contents. However, due to the weak interaction between the surface of the nanoparticles and the polymer, ZnO nanoparticles tend to aggregate together to form large-sized particles in the polymer matrix, affecting the mechanical properties of the rubber.
