FIT-221 heat-shrink tubing gives you more choices to achieve reliable, rugged cabling systems
Heatshrink provides an easy solution to colour coding wires for easy circuit identification or make fast, reliable repairs to nicked or worn insulation
For a secure fit, it is necessary that the tubing's recovered diameter (the diameter after shrinkage) is smaller than the diameter of the area to be insulated
At the same time, the tubing's expanded diameter (the diameter before shrinkage) needs to be large enough to fit easily over the area to be insulated, as well as any connectors attached to it
Benefits of Polyolefin
Polyolefin is a polymer which is often used in heat shrink tubing as it has excellent mechanical and electrical properties
Polyolefin is also flexible, fast-shrinking and can be manufactured in a wide range of colours.
