Due to the need for agricultural tractors to drive on poor rural roads and hard stubble ground, the tires are prone to scratches and punctures. Therefore, the rubber tread and sidewall rubber have good cutting and puncture resistance, and the tread rubber also requires wear resistance. The sidewall rubber also needs to have good resistance to bending, cracking, and aging. It is generally processed from natural rubber, styrene butadiene rubber, and butadiene rubber, and recycled rubber is used in moderation Regenerated rubber powder can reduce costs while ensuring tire performance.

Recycled rubber and recycled rubber powder are processed from waste rubber products and mixed in small amounts in different parts of tractor tires. This can improve the process performance of the rubber material and reduce the cost of raw material 2SLYY427. In the future, the editor will continue to discuss with you the key production process points of mixing rubber recycled resources in various parts of tractor tires.
