Rubber seal performance

Rubber seal performance

Generally speaking, the natural rubber we refer to refers to the natural rubber latex collected from the rubber tree, which is made by solidification and drying. Natural rubber is a natural polymer compound with polyisoprene as the main component, the 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.

Physical characteristics of natural rubber. Natural rubber has high elasticity at room temperature, is slightly plastic, has very good mechanical strength, low hysteresis loss, low heat generation during multiple deformations, so its flex resistance is also very good, and because it is non-polar Rubber, so the electrical insulation performance is good.

Rubber, which is the same as plastic and fiber, is called three synthetic materials. It is a high molecular material with high elasticity and excellent elasticity. The biggest characteristic of rubber is that the elastic modulus is very small, and the elongation is very high. Secondly, it has quite good resistance to air permeability and resistance to various chemical media and electrical insulation. Some special synthetic rubbers have good oil resistance and temperature resistance, and can resist the swelling of fatty oils, lubricating oils, hydraulic oils, fuel oils and solvent oils; cold resistance can be as low as -60 ℃ to -80 ℃, heat resistance As high as +180℃ to +350℃. Rubber is also resistant to various deflections and bending deformations because the hysteresis loss is small. The third characteristic of rubber is that it can be used, blended, and compounded with various materials, and thus modified to obtain good comprehensive performance.
