Heat-shrinkable sleeve (or commonly “shrink sleeve”) is a corrosion protective coating for pipelines in the form of a wraparound or tubular sleeve that is field-applied.
PTFE heat shrink sleeving is made from pure virgin PTFE with no fillers or additives and therefore offer all the exceptional properties of PTFE.
The major characteristic of this high temperature heat shrink is its 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.
Technical Data:Select the correct size sleeve by allowing a generous amount of shrinkage, rather than using a tight sleeve if possible. PTFE shrinks at temperatures over 330°C, so the gun temperature should be at least 400°C. To obtain the higher temperature we suggest a hot air gun of 1.5KW capacity. Parts to be covered that have a large thermal mass, e.g. a solid steel roller, may need preheating when PTFE heat shrink is applied, to prevent chilling of the PTFE sleeve, causing a loose fit.
