Both EPDM and HNBR rubber sheets are widely used in the industry for applications such as seals, gaskets, pads, etc. Here are the similarities and differences between EPDM and HNBR rubber sheets.

EPDM rubber sheets are highly favored for outdoor applications, whether for roofing, rubber gaskets, seals, flooring, or external shock-absorbing pads

EPDM rubber sheets, made from Ethylene-Propylene Diene Rubber (EPDM), a non-polar rubber, exhibit good resistance to a variety of chemicals, including polar solvents. They are resistant to acids, alkalis, water, alcohol, and oxygenated solvents like Methyl Ethylene Ketone (MEK).

EPDM rubber sheets are highly capable of withstanding extreme heat, able to endure temperatures up to +160°C. They also offer superior resistance to hot water and steam compared to other types of rubber sheets.

EPDM rubber sheets are made from EPDM, or Ethylene-Propylene Diene Rubber, which is a non-polar rubber. For this reason, it does not resist oil. However

HNBR rubber sheets possess properties that fall between HNBR and VITON rubber sheets, being resistant to oil, chemicals, and heat. However.

HNBR rubber sheets were first developed in the early 1980s as an advancement over NBR rubber sheets to enhance their properties for more challenging applications. Here are the distinctions between NBR and HNBR rubber sheets

HNBR rubber sheets are made from HNBR, mixed with a variety of chemical rubber compounds and processed through the Calendering Process, resulting in ready-to-use HNBR rubber sheets.
