Fluorinated ethylene propylene (FEP) is a lower-cost alternative to PTFE.Polyvinylidene fluoride (PVDF) tubes are intended for high temperature applications.It is highly flexible, with a very wide operating temperature range of -55 to 220 ☌, making it suitable for protecting sensitive devices against heat. Viton, another fluoropolymer with high chemical resistance, is widely used in hydraulic equipment.PTFE (fluoropolymer) tubes have a wide operating temperature range (-55 to 175 ☌), a low coefficient of friction, and high resistance to chemicals and punctures.Be aware that the shrink tubing will shrink longitudinally as well. Adequate shrink tubing overlap should be included in the finished length of the application. The shrink tubing specified minimum shrunk size should be smaller than your diametric application. Normally the shrink tubing diameter is large enough to fit over all associated coverings and obstructions. Heat shrink tubing is rated by its expansion ratio, a comparison of the differences in expansion and recovery rate.Īpplication: Heat shrink tubing should be sized based on the actual diameter of the cable or feature to be covered. From near microscopically-thin-wall tubing to rigid, heavy-wall tubing, each type has precise design and chemical additives that make it suitable for meeting any of a wide variety of environmental demands. Heat shrink tubing is manufactured in a multitude of varieties and chemical makeups with the exact composition of each type being dependent on the intended application. Heat shrink tubing is available in many different diameters, colors, materials, dielectrics, etc. Heat shrink tubing can provide protection from temperature variations, moisture, corrosion, shock, and other harmful environmental challenges. Heat shrink tubing is used to provide a protective covering for wire cable ends, packaging materials, bundling and organizing wire cable, sealing and protecting solder ends, and more. Shrinkage rates vary from 5 percent of nominal diameter up to 50 percent or more. Heat shrink tube shrinkage is material or product dependant. Heat shrink tubing is a material that contracts or shrinks diametrically when a specified heat source is applied.
