Calcined zinc oxide is also a commonly used functional filler and has a wide range of applications in rubber products. The following is the relevant content of calcined zinc oxide in rubber products:

Strengthen the mechanical properties of rubber: Calcined zinc oxide can be added to rubber as a reinforcing agent to improve its mechanical properties, such as tensile strength, abrasion resistance and hardness. This makes rubber products stronger, more durable and more elastic.

Anti-aging properties: Calcined zinc oxide has good anti-oxidation properties, which can effectively resist the oxidation and aging effects of oxygen, ultraviolet rays and other external factors on rubber products. This enables rubber products to maintain stable performance and appearance during long-term use.

Crack resistance: Calcined zinc oxide can improve the crack resistance of rubber products and reduce the cracking and fracture of rubber products under stress conditions. This is especially important for some rubber products that need to withstand high stress or extrusion, such as tires, seals and vibration absorbing pads.

Antibacterial performance: Calcined zinc oxide has a certain antibacterial effect, which can inhibit the growth of bacteria and mold on the surface of rubber products, thereby improving the hygienic performance and durability of rubber products.

Electrical insulation properties: Calcined zinc oxide can improve the electrical insulation properties of rubber products and reduce electrical conductivity. This makes it used in some rubber products that require electrical insulation, such as cable insulation, insulating gaskets, etc.

Increase product weight: Calcined zinc oxide is a high-density material that can be used to increase the weight of rubber products. This is required in some specific applications, such as in the automotive industry where calcined zinc oxide is used to fill rubber to increase the weight of tires, thereby improving vehicle stability and grip.

According to specific rubber products and requirements, the proportion and processing method of calcined zinc oxide should be reasonably selected to ensure the desired effect. In addition, attention should also be paid to the impact of calcined zinc oxide on the hardness of rubber products.
