3M TMW Tubing

3M TMW Tubing is a semi-rigid translucent heat-shrinkable polyolefin tubing that is co-extruded and selectively cross-linked with an integral, meltable inner wall. When heated in excess of 135°C the adhesive inner wall of the tubing is softened and forced by the shrinking action of the outer wall into contact with all underlying surfaces and small voids. The adhesive forms a flexible bond with a wide variety of rubber, plastics and metals. Upon cooling, 3M TMW tubing provides a tough, protective and insulating barrier, highly resistant to penetration by moisture, chemicals and solvents. #M TMW tubing is rated for continuous operation at temperatures fro -55°C to 110°C and will withstand higher operating temperatures for brief periods. Adhesive reflow will occur at temperatures above 80°C.Information provided by 3M
