3M™ adhesive-lined tubing gives a choice of shrink ratios. The outer wall provides abrasion resistance and the inner wall forms an environmental seal against moisture penetration. It meets both UL/CSA specifications and military specifications.
3M™ EPS-300 tubing is a 3:1 thin-wall tubing offering the advantages of integral, dual wall construction. The tubing is made from flame-retardant (except clear), flexible polyolefin-lined with an internal layer of special thermoplastic adhesive.
3M™ MW tubing is a 2.5:1 semi-rigid, heat shrinkable polyolefin tubing that is co-extruded and selectively cross-linked to provide an integral, meltable inner wall.
