Features
- 4:1 shrink ratio allows for fewer sizes to cover numerous splice configurations and diameters
- Thick adhesive liner forms an effective barrier against fluids and moisture penetration
- Minimum shrink temperature: 70°C
- Continuous operating temperature: -45°C to 125°C
- Minimum full shrink temperature: 125℃
- Standard color: The jacket is black, clear (other colors can be customized), and the adhesive is black
