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
v Shrink ratio: 3:1, 4:1
v Good hot-melt adhesive and high expansion ratio to provide good sealing protection.
v Conveniently repair most damaged cable jackets without removing connectors.
v The adhesive bonds to a wide variety of plastics, rubbers, and bls.
v EVA hot melt adhesive or PA adhesive are available.
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: 110℃
