The strength of the natural rubber hand wheel is high in the elastic material, and the strength of the raw rubber, the rubber compound and the vulcanized rubber of the natural rubber hand wheel are relatively high. The tensile strength of the unvulcanized rubber hand wheel is called the green strength, and the natural rubber hand wheel has a green strength of 1.4 to 2.5 MPa. The appropriate green strength is necessary for the rubber hand wheel forming. The natural rubber hand wheel has a high tear strength of up to 98 kN/m, and its wear resistance is also good.
