CB-DWT is adhesive –lined, flexible, halogen free and flame-retardant polyolefin heat-shrinkable dual wall tubing which is RoHS complaint and meets Sony’s environment-related substance requirements. This tubing has good mechanical strength and provide protection from fluids, moisture and sorrosion. 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.
