The elasticity of the natural rubber hand wheel is high in the elasticity of the raw rubber and the vulcanized rubber having a low crosslink density. For example, in the range of 0-100 ° C, the resilience is between 50-85 ° C, the elastic modulus is only 1 / 3000 of steel, the elongation can reach 1000%, stretch to 350%, and then retracted to permanent The deformation is only 15%, the natural rubber hand wheel has higher elasticity, which is second only to the butadiene rubber hand wheel in the universal rubber hand wheel.
