With high tensile strength and elasticity, our EPDM gaskets provide great electrical insulation and are highly resistant to aging, water, steam, weather, ultraviolet radiation, and ozone. With a low compression set, our EPDM gaskets remain highly flexible at temperatures ranging from -45°C to 150°C. \u003c\/p\u003e\n\u003cp\u003eIdeal for MEA electrolyzers and GDE flow cells, our EPDM gaskets act as a seal to prevent reactant gas and electrolyte leaking, control mechanical compression across the active area, and secure fragile ion exchange membranes in position protecting them from stress and damage during assembly processes and electrochemical reactions.\u003c\/p\u003e\n\u003cp\u003eEPDM exhibits excellent resistance to alkalis such as sodium hydroxide and potassium hydroxide. At normal temperatures it handles dilute and moderately concentrated alkaline solutions well, making it ideal for water treatment, chemical processing, and electrochemical cell settings. EPDM gaskets are preferred to other commonly used materials (PTFE and FKM) to handle alkaline conditions in MEA electrolyzers and GDE flow cells.\u003c\/p\u003e\n\u003ch2 id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003chr\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eEPDM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eIdeal Operating Temperatures\u003c\/th\u003e\n\u003ctd\u003e-45 - 150°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eOverall Dimensions\u003c\/th\u003e\n\u003ctd\u003e52 mm x 52 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eAvailable Window Dimensions\u003c\/th\u003e\n\u003ctd\u003e12 mm x 12 mm, 23 mm x 23 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eAvailable Thicknesses\u003c\/th\u003e\n\u003ctd\u003e0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 3.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003ePack Size\u003c\/th\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cfigure\u003e\u003cimg width=\"848\" loading=\"lazy\" height=\"439\" alt=\"PTFE Gasket Dimension Diagram\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/membrane-electrode-assembly-electrolyzer-gasket-dimensions.svg?\"\u003e\n\u003cfigcaption\u003eEPDM Gasket Dimensions\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003ch2 id=\"gallery\"\u003eEPDM Gasket Gallery\u003c\/h2\u003e\n\u003chr\u003e\n\u003cdiv class=\"carousel-container carousel-gallery\"\u003e\n\u003cdiv class=\"carousel-track ease-in-out-transition\"\u003e\n\u003ca class=\"carousel-item\" href=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-with-mea.jpg?Vwidth=1620\" title=\"EPDM Gaskets\"\u003e \u003cimg alt=\"EPDM Gaskets\" height=\"280\" loading=\"lazy\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-with-mea.jpg?Vwidth=420\u0026amp;height=280\u0026amp;crop=center\" width=\"420\"\u003e \u003c\/a\u003e \u003ca class=\"carousel-item\" href=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-setup.jpg?width=1620\" title=\"EPDM Gaskets for MEA Cells\"\u003e \u003cimg alt=\"EPDM Rubber Gaskets for MEA Cells\" height=\"280\" loading=\"lazy\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-setup.jpg?width=420\u0026amp;height=280\u0026amp;crop=center\" width=\"420\"\u003e \u003c\/a\u003e \u003ca class=\"carousel-item\" href=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-12mm.jpg?Vwidth=1620\" title=\"EPDM 12mm Gasket\"\u003e \u003cimg alt=\"EPDM 12mm Gasket\" height=\"280\" loading=\"lazy\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-12mm.jpg?Vwidth=420\u0026amp;height=280\u0026amp;crop=center\" width=\"420\"\u003e \u003c\/a\u003e \u003ca class=\"carousel-item\" href=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-mea-setup.jpg?Vwidth=1620\" title=\"EPDM Gaskets for MEA Cells\"\u003e \u003cimg alt=\"EPDM Gaskets for MEA Cells\" height=\"280\" loading=\"lazy\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/epdm-gasket-mea-setup.jpg?Vwidth=420\u0026amp;height=280\u0026amp;crop=center\" width=\"420\"\u003e \u003c\/a\u003e\n\u003c\/div\u003e\n\u003ca class=\"carousel-left-control\" role=\"button\"\u003e \u003csvg class=\"icon icon-chevron-left\"\u003e\u003cuse href=\"#icon-chevron-left\"\u003e\u003c\/use\u003e\u003c\/svg\u003e \u003cspan class=\"sr-only\"\u003ePrevious\u003c\/span\u003e \u003c\/a\u003e \u003ca class=\"carousel-right-control\" role=\"button\"\u003e \u003csvg class=\"icon icon-chevron-right\"\u003e\u003cuse href=\"#icon-chevron-right\"\u003e\u003c\/use\u003e\u003c\/svg\u003e \u003cspan class=\"sr-only\"\u003eNext\u003c\/span\u003e \u003c\/a\u003e\n\u003c\/div\u003e\n\u003ch2 id=\"literature\"\u003eLiterature and Reviews\u003c\/h2\u003e\n\u003chr\u003e\n\u003col\u003e\n\u003cli\u003eJ.
