Heat Shrink Tubing Range

Heat Shrink Tubing

Shrinkflex Heat Shrink Tubing range is available in many grade and colors. It is a flexible, pre-stretched tubing, engineered from a wide range of polymers, that will shrink to a fixed diameter when sufficient heat is applied. Its diameter and thickness can vary, and it is rated by its expansion ratio.

Shrinkflex 2:1 Polyolefin Heat Shrink Tubing is available in 11 Colours.
When economy is the driving force, Shrinkflex 2:1 Polyolefin Heat Shrink Tubing is the answer. Not as versatile as a high shrink ratio product. Shrinkflex 2:1 Polyolefin Heat Shrink Tubing will still slide easily over small plugs and connectors and provide a tight seal in many applications.
