The 328Pcs 8-Size Heat Shrink Tubing Kit (1mm-10mm) provides electrical insulation through thermal contraction. Under heat, the 2:1 shrink ratio creates a mechanical seal over soldered connections or frayed wires. Polyolefin construction withstands operating temperatures from -55°C to 125°C without material degradation.
Key Features
- 2:1 Shrink Ratio: Thermal contraction to 50% diameter at 70-110°C. Fits tightly over irregular solder joints.
- Flame-Retardant Polyolefin: Chemical-resistant material prevents fire spread in circuits. Protects copper from road dust and humidity.
- 8-Size Assortment: 328 pieces ranging from 1mm to 10mm diameters. Handles diverse wire gauges in one kit.
- 600V Voltage Rating: Electrical insulation for circuits up to 600 volts. Stops short circuits in domestic power lines.
- 20 kV/mm Dielectric Strength: Resistance against current leakage through the polyolefin material. Keeps signals clean in high-density wiring.
Frequently Asked Questions
How to use heat shrink tubing for wires?
Apply heat between 70°C and 110°C using a heat gun or lighter. The material contracts to 50% of its original size for a tight fit.
What is the maximum voltage for these tubes?
These tubes support up to 600V for safe electrical insulation. A dielectric strength of 20 kV/mm prevents current leakage between adjacent wires.
