Rubber sheet that is resistant to expansion, contraction, softening, or cracking in acidic and alkaline media.

Acid and alkali-resistant rubber sheet refers to a rubber plate that is not easily expanded, contracted, softened, or cracked in acidic or alkaline media, primarily made of三元乙丙橡胶（EPDM）。This material boasts characteristics of 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 other chemical substances, with a thickness range of 1 to 80mm and a width up to 2000mm.
