Description:
PTFE Shrink Tubing is available in 2:1 and 4:1 shrink ratios, and is widely used in military
applications because of its high continuous use temperature (250°C), and outstanding chemical
resistance.
PTFE 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 is the use of a controlled temperature oven;
however this is impractical with large harnesses or temperature sensitive components.
PTFE heat-shrink sleeves are made from pure virgin PTFE with no fillers or additives and therefore
offer all the exceptional properties of PTFE. The major characteristic is a upper continuous working
temperature of 260° C. This exceeds that of any other heat-shrink polymer. In addition it is completely
resistant to virtually all chemicals, and UV radiation. It is available in 4:1 and 2:1 shrink ratios, and the
shrinking temperature is 327° C.
Applications:
PTFE sleeves are mainly used in various electric cable, electric wire, protecting cover, inner liner
pipes for corrosive fluids and gas, heat exchange machine tube and fluids meter tube.
