DW125 Soft And High Times Double Wall Heat Shrinkable Sleeve
Application
Dual-wall adhesive-lined heat shrinkable tubing is made by co-extrusion of 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 insulation and sealing of electrical and electronic components, automotive and communication industry.
Characteristics
Good hot-melt adhesive and high expansion ratio to provide good sealing protection.
Environmental sealing and protection of electrical applications.
Conveniently repair most damaged cable jackets without removing connectors.
EVA hot melt adhesive or PA adhesive are available.
High Shrink ratio 3:1 and 4:1 allows for insulation and sealing of irregular shapes.
Flexible, flame retardant
ROHS and REACH compliant
Color
Standard color: Black
