SEM photographs: Added in rubber formula as a substitute for common zinc oxide, nanometer zinc oxide, for its small size and surface effects, can improve crosslinking density, adhesive force, anti-tear performance, heat dissipation performance and mechanical performance, reduce abrasion loss and extend the life of rubber products. Used in daily sanitary rubber products, nanometer zinc oxide has the virtue of anti-bacterium, decomposition of peculiar odour, UV resistance and aging resistance, etc. |
