Rubber sheeting made from EPDM (ethylene propylene diene monomer) rubber is one of the most multi-purpose types of rubber sheets. Thanks to very good resistance to weather and thermal aging they are used mainly in outdoor applications. Sheets resistant to diluted acids and bases, good resistance to inorganics acids: sulfuric acid (H₂S0₄), bases: sodium hydroxide (Na0H) and low resistance to organic acids e.g. acetic acid (CH₃C00H).
