Introduction of Anti-aging Agents:
Anti-aging agents are highly effective anti-cracking waxes with white to light yellow flake appearance. They are mainly composed of microcrystalline wax with medium molecular weight distribution and selected paraffin wax. They are used to protect rubber products from the influence of ozone and weather factors. They have excellent ozone resistance and anti-aging properties. Relying on their excellent anti-aging properties, anti-aging agents are widely used in the production of rubber products.
Features of Physical Anti-aging Protectants:
Physical anti-aging protectants can effectively protect rubber products from the effects of ozone and weather, especially when exposed to light and air, which can significantly reduce cracking and extend the service life of rubber products. Physical anti-aging protectants have a wide range of applications, not only for tires, but also for conveyor belts, cable sheaths, industrial molded and extruded products and other fields. Physical anti-aging protectants can maintain their stability and protective effects even in high temperature environments (up to 50°C), and can still maintain stable performance in some high-temperature working environments. Physical anti-aging protectants can be customized according to customer needs to meet customer needs under different working conditions.
Applications of Anti-aging Agents:
1. In tire manufacturing, anti-aging agents can be used to improve the ozone resistance of rubber and prevent cracking caused by long-term exposure to sunlight and ozone.
2. Anti-aging agents are suitable for conveyor belts and cable sheath materials that require high durability and anti-aging, ensuring good performance in various harsh environments.
3. Anti-aging agents are particularly suitable for industrial molded and extruded profile products used at high temperatures, providing excellent durability and anti-aging effects.
4. Anti-aging agents are widely used in rubber products that need to be exposed to high temperature environments for a long time, such as industrial equipment, automotive parts, etc., to extend their service life and improve ozone resistance.
Instructions Use of Physical Aging Inhibitors:
Mode of action:
Due to their low solubility, physical aging inhibitors migrate to the surface of sulfides and form a protective film. They remain stable at high temperatures (up to 50°C). The protective film formed has excellent stability against dynamic stresses and helps to enhance the ozone and oxidation resistance of rubber.
Operational advice:
Physical aging inhibitors exist in the form of flakes, which are easy to weigh and mix. To ensure good dispersion, it is recommended to add them at the beginning of mixing and ensure that the mixing temperature exceeds their melting point.
Recommended dosage:
Tires: 1-4 phr (partial formulation);
Other rubber products: Depending on the type of rubber, the maximum dosage is 10 phr.
