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. The reason why the natural rubber hand wheel has high mechanical strength is that it is a self-reinforcing rubber hand wheel which, when stretched, causes the macromolecular chain to be oriented in the direction of stress to form crystals.
Electrical properties of natural rubber handwheels Natural rubber handwheels are non-polar materials and are a good insulating material. When the natural rubber hand wheel is vulcanized, the insulation property is lowered due to the introduction of polarity factors such as sulfur, an accelerator, and the like.
