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
