TEMCo Industrial adhesive lined shrink tubing is a 3:1 flexible tubing offering the advantages of integral, adhesive-lined construction. The tubing is made from flexible polyethylene with an internal layer of special thermoplastic adhesive. The heat-shrinkable outer wall is selectively cross-linked, while maintaining the high flow and excellent adhesion of the inner sealant liner. When heated in excess of 121 deg C (250 deg F), the tubing rapidly shrinks to a skintight fit, forcing the melted adhesive lining to flow and cover the substrate. The adhesive forms a flexible bond with a wide variety of rubbers, plastics and metals. Upon cooling, the adhesive solidifies, forming a permanent, non-drying, flexible and water resistant barrier. Adhesive reflow will occur at temperatures above 80 deg C (176 deg F).
