Usually, what we call natural rubber refers to the natural rubber latex collected from the rubber tree, which is a solid product made by coagulation, drying and other processing procedures. Natural rubber is a natural polymer compound with polyisoprene as the main component. Its molecular formula is (C5H8)n. Its rubber hydrocarbon (polyisoprene) content is more than 90%, and it also contains a small amount of protein and fatty acid. , sugar and ash, etc.
Physical properties of natural rubber. Natural rubber has high elasticity at room temperature, is slightly plastic, has very good mechanical strength, low hysteresis loss, and low heat generation during multiple deformations, so its flexural resistance is also very good, and because it is non-polar. Rubber, so the electrical insulation performance is good.
