Product Description

The 2mm Polyolefin Heat Shrink Tube is a high-quality insulation and protection sleeve essential for electrical wiring, hobbyist electronics, and DIY repairs. Made from cross-linked polyolefin, this tubing features a 2:1 shrink ratio, meaning it will contract to half its original diameter when heat is applied. It provides a snug, form-fitting layer that protects wire joints from abrasion, corrosion, and environmental moisture. Unlike electrical tape, heat shrink tubing will not unravel or leave a sticky residue over time, ensuring a professional, long-lasting finish for cable management and connector strain relief.

Key Features

  • 2:1 Shrink Ratio: Shrinks from 2mm down to 1mm, providing a tight grip around thin gauge wires (22AWG to 26AWG) and small electronic components.

  • Excellent Dielectric Strength: Rated for 600V, making it safe for both low-voltage DC logic circuits and standard AC internal wiring.

  • Low Shrink Temperature: Begins to contract at just 70°C, allowing for quick application using a standard heat gun, or even a lighter in emergency repairs.

  • High Chemical Resistance: Resistant to common workshop fluids including oils, fuels, and acids, preventing degradation in automotive or industrial environments.

  • Clean & Flexible: Maintains significant flexibility after shrinking, allowing the protected wire to bend without cracking the insulation.

Technical Details

  • Length: 1 Meter (Continuous).

  • Color: Matte Black.

  • Tensile Strength: ≥10.4 MPa.

Prototyping and Engineering Tips from Robogears

  • Choosing the Right Size: Always select a tube size slightly larger than the wire or solder joint you are covering. Since this is a 2mm tube, it is perfect for single strands of hookup wire. If you have a bulky solder "blob," you might need a 3mm or 4mm tube instead.

  • Uniform Heating: For the best results, use a Heat Gun rather than a flame. Start from the center of the tube and move toward the ends; this pushes air out and prevents "bubbles" from being trapped inside the sleeve.

  • Longitudinal Shrinkage: Note that while the diameter shrinks by 50%, the tube will also shrink slightly in length (usually about 5–10%). Always cut your piece slightly longer than the area you intend to cover.

  • Labeling Strategy: If you are building a complex wiring harness, you can use a fine-tip permanent silver marker to write on the black surface before shrinking. The text will become smaller and more durable once the tube is heat-treated.

  • Strain Relief Enhancement: If you are protecting a point where a wire enters a connector, double-layer the tubing. Apply one layer, shrink it, then apply a second, slightly wider layer over the top. This significantly increases the mechanical strength and prevents the wire from snapping due to fatigue.

Package Includes

  • 1 x 1 Meter 2mm Polyolefin Heat Shrink Tube (Black)

Disclaimer: Do not apply excessive heat to the same spot for too long, as this can melt the underlying wire insulation or cause the tube to char. Always perform shrinking in a well-ventilated area. Not intended for use as primary insulation on high-tension (HT) power lines.
