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

Acid and alkali-resistant rubber sheets are made of rubber that is not easily expanded, contracted, softened, or cracked in acidic or alkaline environments, primarily composed 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].The working medium includes dilute acids, dilute alkalis, strong acids, strong alkalis, and other chemical substances, with thickness ranging from 1 to 80mm and widths up to 2000mm.
