| Description | Usages | Operating Temp | Shrink Temp | Packaging |
|---|---|---|---|---|
| Semi-Rigid, dual wall polyolefin heat-shrinkable tubing. When heated the inner liner melts and flows too encapsulate (not adhesive lined) components or splices contained within. | Recommended in applications for connections and wire harnesses where filling voids and intersectices is of importance. Provides good strain relief because it does not adhere to the substrate material. It can be removed for repair of components. | -55 C to +110 C | 130 C | Bag |
