Beskrivelse
General Information
The environmentally friendly double-wall (dual wall) tube is composed of two layers
Outer Layer: Soft flame-retardant and insulated polyolefin
Inner Layer: Hot-melt adhesive
Function: Forsegling, waterproof, anti-corrosion, air leakage and insulation protection. The high-magnification shrinkage characteristic can meet the protection of more variable diameter components.
Characteristic
– 3:1 shrink ratio
– Low longitudinal shrinkage
– Flame retardant (out jacket only)
– Super sealing against water, moisture or other contaminates
– Continuous operating temperature : -45ºC-125ºC
– Shrink Temperature:125ºC
– Meet RoHs
