>> Product Introduction
Double-wall heat shrink tubing is made of soft polyolefin and hot melt adhesive co-extruded and is used for insulation protection of wires and cables, wiring and connectors that need to be sealed, waterproof and moisture-proof. It can be well applied in many industries such as electronics, automobiles and communications.
>> Product Advantage
Shrink ratio 3:1 or 4:1
Excellent hot melt adhesive and high shrink ratio provide excellent sealing
For sealing and insulation protection of electronic connection parts
Damaged insulation can be easily repaired without removing the connector
Continuous use temperature range: -55℃ ~ 125℃
Initial shrinkage temperature: 80°C
Minimum complete shrinkage temperature: 110℃
