Rubber sheets that are resistant to expansion, contraction, softening, or cracking in acidic or alkaline mediums.

Alkali and acid-resistant rubber sheets refer to rubber plates that are not easily swollen, shrunk, softened, or cracked in acidic or alkaline media, primarily made of ethylene propylene diene monomer (EPDM). This material features resistance to aging, ozone, and chemical corrosion, maintaining stable performance when in contact with alkaline solutions, diluted acids, and ketones [1]. The working medium includes dilute acids, dilute alkalis, strong acids, strong alkalis, and various chemical reagents. The thickness range is 1 to 80mm, and the width can reach 2000mm.
