With special formulations, it can even withstand intermittent high temperatures up to 160\u2103. Its low temperature resistance is equally impressive, maintaining good elasticity even at -50\u2103.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">EPDM exhibits excellent ozone and UV aging resistance, making it less prone to cracking even after years of outdoor exposure. Therefore, it is widely recognized as an ideal material for outdoor sealing applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">EPDM exhibits excellent resistance to various polar chemical media, including hot water, steam, dilute acids, dilute alkalis, detergents, phosphate ester hydraulic oils, and various salt solutions. However, it is not resistant to mineral oils, fuels, or non-polar solvents (such as benzene, toluene, gasoline, kerosene, etc.), making it unsuitable for applications involving contact with oils or non-polar solvents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">EPDM rubber also exhibits excellent electrical insulation properties, with a volume resistivity reaching up to 10\u00b9\u2075 \u03a9\u00b7cm and a breakdown voltage of approximately 20-30kV\/mm. Additionally, it boasts a low compression set and good resilience, making it ideal for dynamic sealing applications where it is subjected to long-term compression.In addition, EPDM material is non-toxic and odorless, meeting FDA and food-grade requirements, making it suitable for use in drinking water and food contact scenarios. It also exhibits excellent resistance to water vapor and superheated water, making it ideal for use in sanitary ware, heating, and steam sealing systems.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-b05bd3ef\" class=\"wp-block-themeisle-blocks-advanced-columns alignwide has-1-columns has-desktop-equal-layout has-tablet-equal-layout has-mobile-equal-layout has-vertical-unset\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div id=\"wp-block-themeisle-blocks-advanced-column-aad48113\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<div id=\"wp-block-themeisle-blocks-tabs-df28e45a\" class=\"wp-block-themeisle-blocks-tabs is-style-border\"><div class=\"wp-block-themeisle-blocks-tabs__content\">\n<div data-title=\"&lt;strong&gt;&lt;strong&gt;Application Field&lt;\/strong&gt;&lt;\/strong&gt;\" class=\"wp-block-themeisle-blocks-tabs-item\"><div class=\"wp-block-themeisle-blocks-tabs-item__header\" tabindex=\"0\"><strong><strong>Application Field<\/strong><\/strong><\/div><div class=\"wp-block-themeisle-blocks-tabs-item__content\">\n<p class=\"wp-block-paragraph\">EPDM seals, which are sealing rings made of ethylene propylene diene monomer rubber, are widely used in multiple industries due to their unique weather resistance, water resistance, and chemical resistance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Automotive manufacturing: <\/strong>In the automotive field, EPDM seals are commonly used for door seals, window guide channels, cooling system pipeline seals, brake chamber diaphragms, and wiper rubber strips. Their excellent weather resistance and heat aging resistance enable them to withstand exposure to sunlight, rain and snow, as well as the high temperature and humidity environment of the engine compartment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>HVAC and Plumbing:<\/strong>&nbsp;EPDM sealing rings are common sealing components used in pipe connections, faucet valve cores, water heaters, water purification equipment, water pumps, and valves. They exhibit excellent resistance to hot water, steam, and common cleaning agents, ensuring long-term leak-free performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bathroom and Architecture: <\/strong>In shower rooms, floor drains, siphonic toilets, aluminum alloy doors and windows, and curtain wall systems, EPDM seals are used for waterproofing, sound insulation, airtightness, and shock absorption. Their resistance to ultraviolet radiation and ozone aging makes them far superior to ordinary rubber in terms of lifespan in outdoor architectural sealing applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Food and Medical:<\/strong>&nbsp;FDA-compliant EPDM seals are used in food conveyor pipes, beverage filling machines, water purification filters, and certain non-implantable medical devices (such as dialysis machine tubing seals). Their non-toxic nature and resistance to disinfectants ensure hygienic safety.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Industrial and hydraulic systems: <\/strong>In brake systems, water-glycol hydraulic pipelines, hot steam pipelines, and some chemical medium delivery systems, EPDM seals can withstand high-temperature water and dilute acid\/alkali liquids. However, their use must be avoided in oil-containing hydraulic systems (such as mineral oil-based hydraulic fluids).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>New energy and outdoor equipment: <\/strong>Solar water heating systems, outdoor distribution boxes, charging pile seals, garden sprinkler connectors, etc., also extensively utilize EPDM seals. Their long-term anti-aging and weather resistance capabilities can significantly reduce maintenance costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In summary, EPDM rubber materials and their EPDM seals play an indispensable sealing role in automotive, construction, plumbing, food, medical, and numerous industrial fields due to their excellent weather resistance, hot water resistance, ozone resistance, and wide temperature adaptability. They are highly cost-effective general-purpose weather-resistant sealing materials.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<hr class=\"wp-block-separator alignwide has-alpha-channel-opacity\"\/>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-9a0e83fe\" class=\"wp-block-themeisle-blocks-advanced-columns alignwide has-1-columns has-desktop-equal-layout has-tablet-equal-layout has-mobile-equal-layout has-vertical-unset\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div id=\"wp-block-themeisle-blocks-advanced-column-5daca14f\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<div class=\"wpcf7 no-js\" id=\"wpcf7-f1426-o1\" lang=\"zh-CN\" dir=\"ltr\" data-wpcf7-id=\"1426\">\n<div class=\"screen-reader-response\"><p role=\"status\" aria-live=\"polite\" aria-atomic=\"true\"><\/p> <ul><\/ul><\/div>\n<form action=\"\/de\/wp-json\/wp\/v2\/products\/1441#wpcf7-f1426-o1\" method=\"post\" class=\"wpcf7-form init\" aria-label=\"\u7559\u8a00\u8868\u5355\" enctype=\"multipart\/form-data\" novalidate=\"novalidate\" data-status=\"init\">\n<fieldset class=\"hidden-fields-container\"><input type=\"hidden\" name=\"_wpcf7\" value=\"1426\" \/><input type=\"hidden\" name=\"_wpcf7_version\" value=\"6.1.7\" \/><input type=\"hidden\" name=\"_wpcf7_locale\" value=\"zh_CN\" \/><input type=\"hidden\" name=\"_wpcf7_unit_tag\" value=\"wpcf7-f1426-o1\" \/><input type=\"hidden\" name=\"_wpcf7_container_post\" value=\"0\" \/><input type=\"hidden\" name=\"_wpcf7_posted_data_hash\" value=\"\" \/>\n<\/fieldset>\n<div class=\"uacf7-form-wrapper-container uacf7-form-1426  \"><div class=\"cf7-original-style\">\n\n  <div class=\"cf7-row\">\n    <div class=\"cf7-col-half\">\n      <label>Name <span class=\"required\">*<\/span><\/label>\n      <span class=\"wpcf7-form-control-wrap\" data-name=\"your-name\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-text wpcf7-validates-as-required cf7-input\" aria-required=\"true\" aria-invalid=\"false\" value=\"\" type=\"text\" name=\"your-name\" \/><\/span>\n    <\/div>\n\n    <div class=\"cf7-col-half\">\n      <label>Email <span class=\"required\">*<\/span><\/label>\n      <span class=\"wpcf7-form-control-wrap\" data-name=\"your-email\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-email wpcf7-validates-as-required wpcf7-text wpcf7-validates-as-email cf7-input\" aria-required=\"true\" aria-invalid=\"false\" value=\"\" type=\"email\" name=\"your-email\" \/><\/span>\n    <\/div>\n  <\/div>\n\n  <div class=\"cf7-row\">\n    <div class=\"cf7-col-half\">\n      <label>Country<\/label>\n      <span class=\"wpcf7-form-control-wrap\" data-name=\"your-country\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-text cf7-input\" aria-invalid=\"false\" value=\"\" type=\"text\" name=\"your-country\" \/><\/span>\n    <\/div>\n\n    <div class=\"cf7-col-half\">\n      <label>Industry<\/label>\n      <span class=\"wpcf7-form-control-wrap\" data-name=\"your-industry\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-text cf7-input\" aria-invalid=\"false\" value=\"\" type=\"text\" name=\"your-industry\" \/><\/span>\n    <\/div>\n  <\/div>\n\n  <div class=\"cf7-row\">\n    <div class=\"cf7-col-full\">\n      <label>Message <span class=\"required\">*<\/span><\/label>\n      <span class=\"wpcf7-form-control-wrap\" data-name=\"your-message\"><textarea cols=\"40\" rows=\"7\" maxlength=\"2000\" class=\"wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required cf7-textarea\" aria-required=\"true\" aria-invalid=\"false\" name=\"your-message\"><\/textarea><\/span>\n    <\/div>\n  <\/div>\n\n  <div class=\"cf7-row\">\n    <div class=\"cf7-col-full\">\n      <label>Upload Drawing<\/label>\n      <span class=\"wpcf7-form-control-wrap\" data-name=\"your-drawing\"><input size=\"40\" class=\"wpcf7-form-control wpcf7-file cf7-input\" accept=\".pdf,.dwg,.dxf,.zip,.jpg,.jpeg,.png\" aria-invalid=\"false\" type=\"file\" name=\"your-drawing\" \/><\/span>\n      <small class=\"cf7-file-note\">\n        Accepted formats: PDF, DWG, DXF, ZIP, JPG and PNG.
