3M MW Heat Shrink Tubing

产品说明

3M Heat Shrink Tubing MW is a semi-rigid, 110°C heat-shrinkable polyolefin tubing that is a co-extruded and selectively cross-linked to provide an integral, meltable inner wall. When heated in excess of 135°C, the inner meltable wall of the tubing is simultaneously softened and forced by the shrink action into intimate contact with all underlying surfaces, interstices and small voids. Upon cooling, the MW tubing provides a tough protective and insulating barrier, highly resistant to penetration by moisture and the introduction of chemicals and solvents. Adhesive reflow will occur at temperatures about 80°C.
