Additional Information

Nelco Products offers adhesive, semi-​rigid, polyolefin heat shrink tubing in a variety of sizes. This 1/8" adhesive shrink tubing will shrink down to 40% of its size when heated to a minimum temperature of 135°C (275°F). The standard operating temperature of the semi-​rigid polyolefin tubing is from -55°C (-67°F) to 110°C (230°F). The tubing however, can withstand higher temperatures for a short period of time, but adhesive will reflow will occur at temperatures above 80°C (176°F). This semi-​rigid heat shrink tubing shrink tubing solution meets all SAE-​AMS-​DTL-​23053/4D and UL specifications. The adhesive-​lined shrink tubing is currently available in Class 1 only and in the color black.
