Ordinary rubber conveyor belts, rubber V belts, and rubber sheets are mostly processed with natural rubber as the main raw material. The appropriate amount of tire reclaimed rubber can effectively reduce production costs. In actual production, the performance requirements of different parts of the rubber conveyor belt, V-belt and rubber plate are different, and the manufacturer needs to design the formula reasonably according to the specific technical index requirements.

Different rubber layers of natural rubber conveyor belts, different rubber layers of natural rubber V-belts, and natural rubber sheets in different occasions have different specific performance requirements. Rubber product manufacturers must reasonably mix tire reclaimed rubber according to actual needs. In actual production, the rubber products that can be mixed with tire reclaimed rubber are more than that. Later, the editor will continue to share with you the mixing skills of tire reclaimed rubber in various natural rubber products.
