Dual Wall Heat Shrink Tubing
Model: SBRS-(4X)GRF
Highly flame retardant, semi-rigid, cross-linked polyolefin heat shrinkable tubing
SBRS-(4X)GRF dual wall heat shrink tubing is highly flame retardant heat shrinkable tubing manufactured with semi-rigid polyolefin construction with an internal layer of adhesive, offering fuse link and splice protection against fluids, moisture and abrasion.
Features
- 3:1 & 4:1 shrink ratio to cover varying splice configurations and substrate profiles
- Jacket and adhesive are exceptionally flame retardant
- Economical way for environmental sealing and protection of automotive fuse-links, electrical splices and terminals
- High resistance to common automotive fluids and solvents
- Semi-rigid and mechanically tough outer jacket provides added strain relief and excellent abrasion protection
- Thick adhesive liner forms an effective barrier against fluids and moisture penetration
- Continuous operating temperature: -45℃～125℃
- Fully shrink temperature: ≥125℃
