class=\"wp-block-themeisle-blocks-tabs-item__content\">\n<p class=\"wp-block-paragraph\">Polytetrafluoroethylene (PTFE), also known as Teflon, is a polymer material with unique properties. Its molecular structure contains fluorine atoms, which endow it with a variety of excellent characteristics, such as high heat resistance, chemical corrosion resistance, low friction coefficient, good electrical insulation, and outstanding surface non-stick properties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PTFE has a melting point of approximately 327\u00b0C, a continuous service temperature range of -200\u00b0C to 260\u00b0C, and can reach 300\u00b0C for short-term use. This wide operating temperature range allows PTFE to maintain stable performance even in high-temperature environments. In addition, the density of PTFE is approximately between 2.13-2.19 g\/cm\u00b3. The fluorine atoms in its molecular chain are evenly and symmetrically distributed, which gives it excellent performance in electrical insulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PTFE also has an extremely low friction coefficient, nearly lower than that of any other material, and features self-lubricating properties that eliminate the need for additional lubricants. This characteristic enables PTFE to achieve high efficiency and long service life in sealing applications for moving parts. At the same time, PTFE exhibits excellent chemical corrosion resistance, capable of withstanding the attack of various chemical substances including acids, alkalis, and salts, making it widely used in industries such as chemical processing, pharmaceuticals, and food production.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-de3a6efa\" 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-3a9b2645\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<div id=\"wp-block-themeisle-blocks-tabs-df18b951\" class=\"wp-block-themeisle-blocks-tabs is-style-border\"><div class=\"wp-block-themeisle-blocks-tabs__content\">\n<div data-title=\"&lt;strong&gt;Application Industry&lt;\/strong&gt;\" class=\"wp-block-themeisle-blocks-tabs-item\"><div class=\"wp-block-themeisle-blocks-tabs-item__header\" tabindex=\"0\"><strong>Application Industry<\/strong><\/div><div class=\"wp-block-themeisle-blocks-tabs-item__content\">\n<p class=\"wp-block-paragraph\">PTFE sealing rings, also known as Teflon sealing rings or PTFE oil seals, are high-performance sealing materials widely used in industrial sealing applications due to their excellent chemical resistance, high temperature resistance, and low friction coefficient.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">Oil &amp; Gas Industry<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the exploration, transportation, and processing of oil and natural gas, sealing rings must withstand high pressure, high temperatures, and corrosive chemicals.
