Corrosion resistance of common valve materials——Natural rubber

Natural rubber

Natural rubber natural rubber is a kind of natural high molecular compound with polyisoprene as the main component. Its molecular formula is (c5h8) n. 91% ~ 94% of its components are rubber hydrocarbons (polyisoprene), and the rest are non rubber substances such as protein, fatty acid, ash, sugar, etc. Natural rubber is the most widely used general rubber.

Corrosion resistance

It has high elasticity and slight plasticity at room temperature, and crystallizes and hardens at low temperature. It has good alkali resistance, but not strong acid resistance. It is insoluble in water, lower ketones and alcohols, and can swell in non-polar solvents such as chloroform and carbon tetrachloride.
