Talking about the performance of rubber seals

Generally speaking, the rubber seals are rubber solids collected from rubber trees, solidified by solidification, drying and other processing steps. In particular, it has excellent resilience, insulation, water repellency and plasticity, and after being properly treated, it also has valuable properties such as oil resistance, acid resistance, alkali resistance, heat resistance, cold resistance, pressure resistance and wear resistance. . Such as rain boots, warm water bags, elastic bands used in daily life; surgeon gloves and blood vessels used in the medical and health industry; various tires used in transportation; industrial conveyor belts, conveyor belts, acid and alkali resistant gloves; Drainage hoses and ammonia bags for agricultural use; air balloons for meteorological measurement; sealing and anti-vibration equipment for scientific experiments; aircraft, tanks, cannons, gas masks for national defense; and even rockets, artificial earth satellites and spaceships Indispensable raw materials for contoured science and technology products。
Let's take a look at its features.：
Physical characteristics：
Natural rubber has high elasticity at room temperature, slightly plasticity, very good mechanical strength, low hysteresis loss, low heat generation during multiple deformations, so its flex resistance is also good, and because it is non-polar Rubber, so electrical insulation is good。    

Chemical properties：
Because of the unsaturated double bond, natural rubber is a chemically reactive substance. Light, heat, ozone, radiation, flexural deformation and metals such as copper and manganese can promote the aging of rubber. Natural rubber is not resistant to aging. The Achilles heel, however, the natural rubber added with anti-aging agent, sometimes can not see much change after exposure for two months in the sun, can still be used as usual after three years of storage in the warehouse.。   

耐介质特性：
Natural rubber has good alkali resistance, but it is not resistant to strong acid. Since natural rubber is a non-polar rubber, it can only resist some polar solvents, but it swells in non-polar solvents. Therefore, its oil resistance and solvent resistance are very poor. Generally speaking, hydrocarbons, halogenated hydrocarbons, and secondary fluids. Ether, higher ketones and higher fatty acids have a solubility in natural rubber, but their solubility is affected by the degree of plasticization, while lower ketones, lower vinegars and alcohols are non-solvents for natural rubber.。

Natural characteristics：
It refers to the solid latex obtained from the rubber tree and solidified by solidification, drying and other processing steps. Natural rubber is a natural polymer compound with polyisoprene as its main component. Its molecular formula is (C5H8)n, its rubber hydrocarbon (polyisoprene) content is above 90%, and it also contains a small amount of protein and fatty acid. , sugar and ash, etc。
