CB-DWT is adhesive-exible, halogen-free and flame-retardant polyolefin heat-shrinkable dual-wall tubing which is RoHS compliant and meets Sonyâs environment-related substance requirements. This tubing has good mechanical strength and provides protection from fluids, moisture and corrosion. CB-DWT is used in a wide variety of electrical applications, including back end connector sealing, breakouts, and connector-to-cable transitions. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.Â
