Heat Shrink vs Cold Shrink Tubing
Side-by-side technical comparison to help engineers and procurement teams make the right specification decision.
| Property | Heat Shrink Tubing | Cold Shrink Tubing |
|---|---|---|
| Installation | Requires heat gun | Pull-out core, no tools |
| Shrink Ratio | 2:1, 3:1, 4:1 | 2:1, 3:1 |
| Material | Polyolefin, PVC, PTFE | EPDM, Silicone |
| Temperature Range | -55C to 135C | -40C to 90C |
| Environmental Seal | Excellent (adhesive-lined) | Excellent (self-fusing) |
| Cost | $ | $$$ |
| Best For | Electrical insulation, general | Hazardous areas, field repair |
When to Choose Heat Shrink Tubing
Electrical insulation, wire bundling, general cable protection, color coding, and any application where a heat gun is available and safe to use.
When to Choose Cold Shrink Tubing
Hazardous/explosive environments where open flame or heat is prohibited, field repairs without power, underground splices, and applications requiring self-fusing silicone seal.
