Rickshaw tires are bicycles, trolleys, human tricycles and other non-motor vehicle inner/outer tires; according to the skeleton material, they can be divided into two categories: cotton cord and nylon cord; according to the position, they mainly include the tread rubber, cord rubber, Sidewall rubber and inner tube rubber, etc. In actual production, a certain proportion of reclaimed tire rubber can be mixed into the tires of the rickshaw, which can effectively reduce the cost of raw materials under the premise of ensuring product quality. The editor shares with you several formulas for tire tread rubber, cord rubber and sidewall rubber mixed with reclaimed tire rubber.

In actual production, the tread reclaimed rubber, fine reclaimed rubber and other products in the tire reclaimed rubber have a better blending effect in the tire tread rubber, sidewall rubber, cord rubber and other parts of the tire; reduce the production of tire 2YLYY111 Cost, manufacturers can also use latex reclaimed rubber, butyl reclaimed rubber (mostly used for inner tires of motorcycles), and the editor will have the opportunity to continue discussing related issues with you later.
