![]() Polyvinylchloride (PVC) is often used as a low-cost alternative to other heat-shrink materials. It also shrinks more longitudinally (lengthwise) than other heat shrinks. It has a low shrink temperature, 80° C (176° F), but a narrower range of operating temperatures, -40° C to +125° C (-40° F to +270° F). The woven structure makes it highly flexible while allowing it to retain strength and abrasion resistance. ![]() However, most polyolefin heat shrink is not UV resistant.įabric heat shrink is a woven blend of materials, a combination of polyolefin and polyester. Shrink temperature is 120° C (229° F), and the material can perform continuously between temperatures of -55° C to +135° C (-67° F to +275° F). Polyolefin is the most common kind of heat shrink material, in part because its properties make it a great choice for most applications. The most common and widely available types of heat shrink are: There are many potential materials for heat shrink. ![]() Then you want to take account of a few other factors before looking closely at the application. Usually, heat shrink is classified according to its material - whether it has single- or double-walled construction - or its shrink ratio. If you understand the different types of heat shrink, you can select what works best for your application. The good news is that this is relatively easy. At BuyHeatShrink, we offer one of the widest selections of heat shrink tubing in the industry and want to make sure that every customer gets the best type of heat shrink for their application. This general label, however, covers a wide variety of issues. As the tube tightens around the wire, it can secure connections, avoid tangling, and insulate against shocks or short-circuits. It works for applications such as insulating or protecting the wiring. Heat shrink usually refers to tubing that contracts when heated.
