2 Times Black Heat Shrink Tube Kit D Flame Retardant Waterproof Heat Shrinkable Cable And USB Cable Polyolefin Round Flat 2:1 Shrink Ratio UL ISO9001
2 Times Black Heat Shrink Tube Kit Flame Retardant Waterproof Cable and USB Insulation

This heat shrink tube kit offers a practical way to insulate and protect electrical cables and USB cables from moisture, heat, and accidental shorts. Made from flame retardant polyolefin, it provides reliable electrical insulation and meets UL certification standards. With a 2:1 shrink ratio, the tubing contracts tightly around wires when heated, creating a protective sleeve that helps extend cable life. Whether you are repairing household electronics, organising computer leads, or working on automotive wiring, this kit gives you the materials needed for secure, professional-looking results. The included set of black tubing is suitable for a variety of standard cable sizes, and the simple cut-and-shrink application means no special tools are required.
Features and Construction

This heat shrink tube kit is built around a single material and a set of clear specifications that ensure consistent performance in electrical insulation tasks. The tubing is designed to shrink evenly when heat is applied, forming a close-fitting layer around the cable.
Material and Build
The tubing is manufactured from polyolefin, a plastic known for its electrical insulation and flame retardant properties. It is UL certified and produced to ISO9001 manufacturing standards, which means it meets recognised safety and quality benchmarks. The material has a dielectric strength of 15 KV/mm and a compressive strength of 10.4 MPa, providing reliable insulation against electrical currents.
Size and Practical Fit
The tubing shrinks at a 2:1 ratio, meaning the diameter reduces to half its original size when heated. It has a minimum shrinkage temperature of 84°C and a maximum of 120°C, and can operate continuously between -55°C and 125°C. The tubing comes in a round or flat shape and can be cut to any length using ordinary scissors or a knife.
Uses and Placement

This heat shrink tube kit is designed for use in a range of settings where cable insulation and protection are needed. It is suitable for both professional electrical work and everyday household repairs.
Event or Professional Use
Electricians, technicians, and installers can use this tubing to insulate connections in control panels, power supplies, and audio or video equipment. The flame retardant quality makes it appropriate for environments where fire safety is a concern, and the UL certification adds confidence for commercial installations.
Everyday Home Use
At home, this kit can be used to repair frayed charging cables, protect USB leads from kinking at the connector joint, or bundle together loose wires behind a computer desk. Simple cut-and-shrink application makes it accessible for anyone comfortable using a heat gun or hairdryer.
Benefits and Buying Value

This kit delivers value through its combination of safety certification, ease of use, and suitability across multiple cable types. The polyolefin material provides both electrical insulation and flame retardancy without requiring complex handling.
Reuse and Low Maintenance
If care is taken during removal, the shrunk tubing can be cut off and replaced without damaging the underlying cable. The material resists moisture and common temperatures, meaning installed tubes typically remain in place without needing regular maintenance. The kit contains enough length for several small repairs or one larger project.
Why Choose This Product
This product stands out for its clear specifications: UL certification, ISO9001 manufacturing, and a wide operating temperature range from -55°C to 125°C. The 2:1 shrink ratio fits most standard cables, and the black colour blends discreetly with common wiring. For anyone needing a basic, reliable heat shrink solution, this kit provides the essential features without unnecessary complexity.
