It consists of a double layer of cross-linked polyolefin and polyamide PA. Widely used in automotive wiring harness, electronic equipment wire connection and other sealed occasions.
Technical Data
It consists of a double layer of cross-linked polyolefin and polyamide PA. Widely used in automotive wiring harness, electronic equipment wire connection and other sealed occasions.
Features
- 4:1 shrink ratio to cover varying splice configurations and substrate profiles
- Flame-retardant and mechanically tough, providing strain relief and abrasion protection for wire splices, terminals, and other components
- Thick adhesive liner forms an effective barrier against fluids and moisture penetration
- Minimum shrink temperature: 110°C [230°F]
- Continuous operating temperature: -40°C to 130°C [-40°F to 266°F]
- Fully shrink temperature: 135℃ [275°F]
- Can be applied for multiple strands wire sealing
