Rubber sheets that are not prone to expansion, contraction, softening, or cracking in acidic or alkaline media.

Acid and alkali-resistant rubber sheets are made of materials that are 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 covers a range of chemicals such as dilute acids, dilute alkalis, strong acids, and strong alkalis, with thickness ranging from 1 to 80mm and widths up to 2000mm.
