For this reason, the material is often enriched with fillers that modify the necessary mechanical properties. The most commonly used material variants of PTFE include:  <\/p>\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/reontech.cz\/en\/material\/virgin-ptfe\/\">PTFE virgin<\/a><\/h3>\n\n<p class=\"wp-block-paragraph\">PTFE virgin is a highly versatile fluoroplastic with exceptional properties. Its extremely low coefficient of friction, excellent chemical resistance and stability over a wide temperature range make it one of the most widely used engineering plastics. It is electrically non-conductive, resistant to ageing and moisture.  <\/p>\n\n<p class=\"wp-block-paragraph\">It is resistant to almost all chemicals, has excellent sliding properties and high resistance to ageing. The material is FDA approved and can be used in the food industry. Due to its lower elasticity, pure Teflon is not suitable for higher mechanical loads. The material also has a lower resistance to abrasion. For more demanding applications, it is therefore preferable to use one of the PTFE-filled variants.    <\/p>\n\n<p class=\"wp-block-paragraph\">Material temperature resistance: -200 \u00b0C to +260 \u00b0C<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Examples of products and uses:<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Seals and insulating elements, slip rings and washers, parts for the chemical industry, electrical insulation components, food and pharmaceutical applications, tank and pipe linings, plain bearings and valves.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/reontech.cz\/en\/material\/ptfe-bronze\/\">PTFE + Bronze  <\/a><\/h3>\n\n<p class=\"wp-block-paragraph\">PTFE + bronze is a composite material combining the advantages of pure PTFE with the strength and stability of bronze filler (bronze content is typically 40% or 60%). It still retains very good sliding properties and chemical resistance. Compared to pure PTFE, the tendency to extrusion is also reduced while maintaining excellent sliding properties. The added bronze also provides increased abrasion resistance.    <\/p>\n\n<p class=\"wp-block-paragraph\">The temperature resistance of the material is -200\u00b0 to +260\u00b0C<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Examples of products and uses:<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Self-lubricating bearings, sliding bushings, piston rings, sealing elements, guides and slide rails in hydraulics and pneumatics, parts for high mechanical loads, components for higher temperature environments.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/reontech.cz\/en\/material\/ptfe-carbon\/\">PTFE + Carbon<\/a><\/h3>\n\n<p class=\"wp-block-paragraph\">PTFE + carbon is a composite material with excellent sliding properties, complemented by higher strength, hardness and wear resistance due to the addition of carbon. Compared to pure Teflon, it has lower thermal expansion, better dimensional stability and longer life under dynamic loading. <\/p>\n\n<p class=\"wp-block-paragraph\">The temperature resistance of the material is -200\u00b0 to +260\u00b0C<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Examples of products and uses:<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Slip and seal bushings, bearings and washers, compression rings, pump and valve components, pneumatic and hydraulic parts, applications requiring high friction and wear resistance, seals for rotating dynamic applications.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/reontech.cz\/en\/material\/ptfe-graphite\/\">PTFE + Graphite<\/a><\/h3>\n\n<p class=\"wp-block-paragraph\">PTFE + graphite is a reinforced composite that combines the excellent sliding properties of Teflon with the strength and thermal conductivity of graphite. The material is characterized by a low coefficient of friction, high dimensional stability and good wear resistance even under higher loads. Graphite also has improved thermal conductivity and reduced water absorption. However, the addition of graphite slightly reduces the chemical resistance.   <\/p>\n\n<p class=\"wp-block-paragraph\">The temperature resistance of the material is -200\u00b0 to +260\u00b0C<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Examples of products and uses:<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Plain bearings and bushings, sealing rings, washers and sliding plates, components for the chemical and food industries, pump and valve parts, parts subject to high friction and dynamic loads.<\/p>\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"5210\" src=\"https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_1-1024x683.jpg\" alt=\"PTFE plus bronz\" class=\"wp-image-5210\" srcset=\"https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_1-1024x683.jpg 1024w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_1-300x200.jpg 300w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_1-768x512.jpg 768w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_1.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">PTFE + bronze &#8211; increased mechanical resistance<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"5214\" src=\"https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_2-1024x683.jpg\" alt=\"PTFE + Uhl&#xED;k\" class=\"wp-image-5214\" srcset=\"https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_2-1024x683.jpg 1024w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_2-300x200.jpg 300w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_2-768x512.jpg 768w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_2.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">PTFE + Carbon &#8211; excellent sliding properties<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"5212\" src=\"https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_4-1024x683.jpg\" alt=\"PTFE virgin\" class=\"wp-image-5212\" srcset=\"https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_4-1024x683.jpg 1024w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_4-300x200.jpg 300w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_4-768x512.jpg 768w, https:\/\/reontech.cz\/wp-content\/uploads\/2026\/05\/PTFE_4.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">PTFE virgin &#8211; excellent chemical resistance, FDA approved<\/figcaption><\/figure>\n<\/figure>\n\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/reontech.cz\/en\/material\/expanded-ptfe\/\">Expanded PTFE<\/a><\/h3>\n\n<p class=\"wp-block-paragraph\">Expandovan\u00fd Teflon je technick\u00fd t\u011bsnic\u00ed materi\u00e1l vyroben\u00fd ze 100 % polytetrafluoretylenu (PTFE).
