Dual Wall Heat Shrink Tubing, SBRS-(4X)GRF

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℃
