Rubber sheet that resists expansion, contraction, softening, or cracking in acidic and alkaline mediums.

Acid and alkali-resistant rubber sheets are rubber plates that are not easily swollen, shrunk, softened, or cracked in acidic or alkaline mediums. They are primarily made of三元乙丙橡胶（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 covers a range of chemicals including dilute acids, dilute alkalis, strong acids, strong alkalis, etc., with thickness ranging from 1 to 80mm and widths up to 2000mm.
