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 121ºC (250ºF), 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 80ºC (176ºF).

About 3:1 Ratio Heat Shrink Tubing

What is it good for? 

Industrial adhesive lined shrink tubing offers excellent protection for electronic components, wire splices, wire bundles and harness breakouts. Automotive, truck and marine wiring splices and harness breakouts are quickly and easily protected from harsh environments. 

What is Shrink Ratio?

Industrial adhesive lined shrink tubing has a 3:1 shrink ratio. This means that the starting diameter of the tubing as supplied is 3 times the fully contracted diameter if allowed to completely shrink. The wall thickness of the tubing is proportional to the percentage of shrinkage.
