PTFE heat shrink tubing has a very high continuous use temperature (260°C), and outstanding chemical resistance. It is available in 2:1 and 4:1 shrink ratios, While it is the best of the entire fluoropolymer heat shrink tubing family, PTFE is also the most difficult to shrink due to its extremely high shrinking temperature (325-340°C).
