Selected ZnO is a kind of special zinc oxide suitable for rubber industry, combined with the elastomer can prevent the absorption of moisture in the air during storage. Because of the more uniform dispersion, compared with the powder zinc oxide extrusion material, the surface of the extrusion material containing the pre-dispersed parent gel ZnO-80 is smoother. Generally, the fixed elongation and tensile strength of vulcanized rubber containing this product are improved, and the elongation at break is also improved.
