NR rubber O-ring(Natural rubber O-ring) has good flexing resistance and flexibility, and because it is non-polar rubber, its electrical insulation performance is good. It has good alkali resistance but not strong acid resistance.

Because natural rubber has a series of physical and chemical properties, especially its excellent resilience, insulation, water resistance and plasticity, and after proper treatment, it also has oil resistance, acid resistance, alkali resistance, heat resistance, cold resistance, pressure resistance, wear resistance and other valuable properties, so it has a wide range of applications.

 

The chemical properties of natural rubber, Because of the unsaturated double bond, natural rubber is a kind of substance with strong chemical reaction ability. Light, heat, ozone, radiation, flexure deformation, copper, manganese and other metals can promote the aging of rubber, and the aging resistance is the fatal weakness of natural rubber. However, the natural rubber with antioxidant can not see much change after two months of exposure in the sun sometimes. In the warehouse It can still be used as usual after three years of storage.
