DWF Marine Use, High-shrink-ratio, Adhesive-lined Heat Shrinkable Tubing
Application
Dual-wall adhesive-lined heat shrinkable tubing is made by excellent polyolefin compounds and hot-melt adhesive. It is used for water-proofing and insulation protection of wire and cable and wire harnesses, and connector-to-cable transitions. It is typically used in the marine industry.
Characteristics
v Good hot-melt adhesive and high expansion ratio to provide good sealing protection.
v Environmental sealing and protection of electrical applications.
v High Shrink ratio 3:1 and 4:1 allows for insulation and sealing of irregular shapes.
v Flame retardant
v ROHS and REACH compliant
Color
v Standard color: Black
v Other colors are available upon request.
Operating Temperature Range
v Operating temperature: -55℃～110℃
v Minimum shrink temperature: 80℃
v Minimum fully recovery temperature: 120℃
Approvals
v SAE AMS-DTL-23053/15
v ABS, DNV 船級社標準
