The electrical properties of natural rubber handwheels are non-grade 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.
The natural rubber hand wheel raw rubber has a glass transition temperature of -72 degrees, a gel flow temperature of 130 degrees, a decomposition temperature of 200, and a violent decomposition temperature of 270 degrees. When the natural rubber hand wheel is vulcanized, its Tg rises and no viscous flow occurs. .
