The rubber plate can be divided into ordinary rubber plate, acid and alkali resistant rubber plate, heat resistant rubber plate, oil resistant rubber plate, conductive rubber plate, flame retardant rubber plate, etc. according to its performance. Natural rubber is the main raw material for producing rubber plate. However, the price of natural rubber is high and the price fluctuates greatly, and the cost is high and difficult to control for the natural rubber plate production enterprises. Therefore, it is starting to use recycled rubber in the rubber plate production with natural rubber as the main raw material. Which natural rubber plate production can use recycled rubber? How to design the formula?
