For over 50 years now, it has been used to provide a protective and insulating sleeve for all types of cables. The working principle is simple: The tubing \u2013\u00a0usually made from heat-resistant materials like PTFE or PVDF\u00a0\u2013\u00a0is slipped over the component to be protected and then heated using a hot air gun. As it heats up, the tubing contracts tightly around the object, forming a snug and durable protective layer. This process \u00a0is what gives the product its name.<\/p>\n<p style=\"text-align: justify;\">There are also so-called &#8220;cold shrink tubes&#8221; that perform the same function but require no heat source. For protecting individual components, shrink films are available. These work in much the same way as the tubes, but come in a different format.<\/p>\n<figure id=\"attachment_3058\" aria-describedby=\"caption-attachment-3058\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3058 size-full\" title=\"Heat shrink tubing with hot melt adhesive\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/12\/Waermeschrumpfschlauch-mit-Heissschmelzkleber.jpg\" alt=\"Heat shrink tubing with hot melt adhesive\" width=\"600\" height=\"402\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/12\/Waermeschrumpfschlauch-mit-Heissschmelzkleber.jpg 600w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/12\/Waermeschrumpfschlauch-mit-Heissschmelzkleber-300x201.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2019\/12\/Waermeschrumpfschlauch-mit-Heissschmelzkleber-110x75.jpg 110w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption id=\"caption-attachment-3058\" class=\"wp-caption-text\">\u00a9 Vitaly Rozhkov \/ Fotolia.com<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"The_Red_or_the_Blue_Cable\"><\/span>The Red or the Blue Cable?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Heat shrink tubing is available in many forms and with a wide range of properties.

It is made from elastomeric materials such as silicone rubber and is pre-stretched onto removable cores or expanded using special tools. During installation, the cores are removed, causing the tubing to contract tightly around the target object. A major advantage: Cold shrink tubing can also be used underwater, making it ideal for challenging environments.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"From_Cable_Repair_to_Wine_Bottles\"><\/span>From Cable Repair to Wine Bottles<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Shrink tubing is typically used for repairing or laying cables.
