DWG  Army Standard Double Wall Heat Shrinkable 
Application 
    DWG Dual-wall adhesive-lined heat shrinkable tubing is made by co-extrusion of excellent polyolefin compounds and hot-melt adhesive with good physical , chemical and electrical properties. Environmentally seals and protects a wide variety of electrical applications, including back end connector sealing, breakout, and connector-to-cable transitions. High shrink ratio makes it possible to protect cable jackets and connectors. DWTM meets the requirements of military standard AMS-DTL-23053 class 3. It is typically used in the insulation and sealing of aerospace, military, electrical and electrical and electronic components, automotive and communication industry.
Characteristics
Shrink ratio:  3:1, 4:1
Good hot-melt adhesive and high expansion ratio to provide good sealing protection.
Conveniently repair most damaged cable jackets without removing connectors. 
The adhesive bonds to a wide variety of plastics, rubbers, and metals.
EVA hot melt adhesive or PA adhesive are available. 
ROHS and REACH compliant
Color
Standard color: Black
Other colors are available upon request.
