Rubber Antioxidant 6PPD is a high-performance antioxidant that is designed to protect rubber products from oxidative degradation caused by environmental factors such as heat, oxygen, and ozone. It is a dark purple-brown solid that is soluble in organic solvents and has a melting point of approximately 46-50°C.

Rubber Antioxidant 6PPD is commonly used in the production of tires, belts, hoses, cables, and other rubber products that are exposed to harsh environmental conditions. It provides superior protection against oxidation and heat aging, helping to extend the service life of rubber products and reduce maintenance costs.

In addition to its antioxidant properties, Rubber Antioxidant 6PPD also has excellent antiozonant properties, which helps prevent the formation of cracks, splits, or blisters in rubber products that are exposed to ozone. This makes it particularly useful in outdoor applications such as tire treads and sidewalls.
