HOW TO SHRINK PTFE HEAT SHRINK TUBES?
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.
WHAT’S THE MAJOR CHARACTER OF PTFE HEAT SHIRNK TUBING?
The major characteristic of this ptfe heat shrink tubing high temperature heat shrink is its upper continuous working temperature of 260°C.
