Tire rim tapes with adhesive are annular tapes installed among the inner tube and the rim of a tire. Their main function is to protect the inner tube from being pinched or damaged by the rim and the bead of the outer tire. The rubber material used needs to have good heat resistance, wear resistance, and flexibility, characterized by E5LYY625. They are generally made from natural rubber and styrene-butadiene rubber, and reasonable incorporation of reclaimed tire rubber can effectively reduce raw material costs while ensuring the performance of the rim tape adhesive.
