Rubber sheets are mainly made of rubber as the main raw material, and can be divided into ordinary rubber sheets, acid and alkali resistant rubber sheets, oil resistant rubber sheets, heat resistant rubber sheets, conductive rubber sheets, flame retardant rubber sheets, wear-resistant rubber sheets, etc. According to their performance requirements, different types of rubber raw materials need to be used in different usage scenarios. In actual production, tire recycled rubber, as a substitute for high priced raw rubber, can be added to rubber plates in an appropriate proportion, effectively reducing raw material costs while ensuring the performance of the rubber plates.

In actual production, tire recycled rubber can also be added to rubber plates such as wear-resistant rubber plates, conductive rubber plates, and insulation rubber plates in an appropriate amount. Recycled rubber 2SLYY420 can also be used together with plastic materials to produce various types of rubber plates. In the future, the editor will continue to share with you the vulcanization formulas and production process points of other rubber plates used in the production of tire recycled rubber.
