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
Good hot-melt adhesive and high expansion ratio to provide good sealing protection.
Environmental sealing and protection of electrical applications.
High Shrink ratio 3:1 and 4:1 allows for insulation and sealing of irregular shapes.
Flame retardant
ROHS and REACH compliant
Color
Standard color: Black
Other colors are available upon request.
