Heat-shrinkable Tube Cabletech CB-HFT Ø3.0 mm Black 1 m

Heat-shrinkable Tube Cabletech CB-HFT Ø3.0 mm Black 1 m is a halogen-free, flame-resistant sleeve designed to insulate and protect cable joints and wire connections. With a 3.0 mm nominal diameter and 1 m length, this tube shrinks when heated to form a tight protective layer, providing electrical insulation, mechanical protection and strain relief in electronics, automotive and general wiring applications.

Advantages

The CB-HFT heat-shrinkable tube is flexible, halogen-free and rated flame-resistant up to 125°C. It offers at least 50% radial shrinkage, maintains dimensional stability with change in length under ±5%, and provides strong mechanical properties including tensile strength above 1.4 MPa and elongation at break over 200%. The product meets VW-1 flammability standards and has concentricity greater than 70%. Certified by UL, CUL and F-Sony Green Partner, it is suitable where halogen-free certification and safety approvals are required.

How to use

Cut the heat-shrinkable tube to the required length, slide it over the joint or connector, and apply heat evenly (for example with a heat gun) until the tube has uniformly shrunk and formed a tight seal. Allow the sleeve to cool before handling to ensure proper recovery and mechanical stability. Follow standard safety procedures for heating and electrical work.

Usage recommendations

For best results, select a tube size that provides appropriate coverage before shrinking and avoid direct high-intensity flame. Use a regulated heat source and heat evenly to achieve uniform shrinkage; verify that operating temperatures do not exceed the tube’s 125°C flame-resistant rating.
