Rubber sheet that is not prone to expansion, contraction, softening, or cracking in acidic or alkaline mediums.

Acid and alkali-resistant rubber sheet refers to a rubber board that is not easily expanded, contracted, softened, or cracked in acidic or alkaline mediums, primarily made of三元乙丙橡胶（EPDM）。This material exhibits resistance to aging, ozone, and chemical corrosion, maintaining stable performance when in contact with alkaline solutions, diluted acids, and ketones [1].Its working medium includes dilute acids, dilute alkalis, strong acids, strong alkalis, and various chemical substances, with a thickness range of 1 to 80mm and a width up to 2000mm.
