Heat Shrink Tube, Natural, 1 ft

PTFE heat shrink tubing (PTFE) is available in 2:1 and 4:1 shrink ratios, and is widely used in military applications (MIL-I-23053/12) because of its high continuous use temperature (250°C), and outstanding chemical resistance. PTFE heat shrink tubing is the most difficult of the three fluoropolymer materials to shrink due to its extremely high shrinking temperature (325-340°C). You can use a heat gun or welding torch to shrink PTFE, but these methods have a tendency to cause the material to overheat in small areas, while under-heating other areas, causing uneven shrinking and potential burning of the material. The most reliable method for shrinking PTFE Teflon is the use of a controlled temperature oven; however this is impractical with large harnesses or temperature sensitive components. PTFE heat shrink tubing is available in a 2:1 shrink ratio and 4:1. The 2:1 is available in up to four different wall thicknesses. Please note: when ordering our 2:1 PTFE Heat shrink, ORDER AS SIZE AFTER SHRINKING.
