In the world of industrial materials, natural rubber sheets have occupied a place in many fields due to their unique properties. However, the question of whether they are resistant to acids and alkalis has always been a focus of attention in the industry, which is closely related to the material’s characteristics and actual application scenarios.
The resistance of natural rubber sheets to acids and alkalis is generally poor, but their wear resistance is relatively excellent. The molecular structure of natural rubber contains a large number of double bonds, which makes its stability significantly decrease when exposed to strong acids and alkalis. Strong acids and alkalis can destroy the molecular structure, causing the rubber sheet to swell, shrink, soften, or even crack. Long-term contact will rapidly deteriorate the material’s performance, making it unable to meet the high-intensity requirements for acid and alkali resistance. At the same time, this molecular structure also makes it less stable against oils, organic solvents, ozone, and ultraviolet rays. In ozone aging tests, surface aging and elasticity loss may occur within just six months, thus losing its usability. These factors further limit its application scenarios, and natural rubber sheets are generally used in environments with severe wear, such as mines and quarries.

The material of acid and alkali resistant rubber sheets is usually synthetic rubber, with ethylene propylene diene monomer (EPDM) rubber sheets being the most common on the market. EPDM is a synthetic elastomer, typically used in external applications because elastomers have excellent resistance to aging, ozone, ultraviolet rays, water, and adverse environmental conditions. The material’s surface is waterproof and has good wear resistance, performing well when in contact with alkalis, diluted acids, and ketones and other chemical substances.
