3M™ EPS-300 Series — 3M™ Thin-Wall Flexible Polyolefin Adhesive-Lined Tubing:

3M Heat Shrink Tubing EPS-300 is a thin-wall tubing offering the advantages of integral, adhesivelined construction. The tubing is made from flame-retardant, flexible polyolefin with an internal layer of special thermoplastic adhesive. The heat-shrinkable outer wall is selectively cross-linked, while the adhesive maintains high flow and excellent adhesion characteristics. When heated in excess of 121°C (250°F), 3M EPS-300 tubing rapidly shrinks to a skintight fit, forcing the melted adhesive 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 durable, non-drying, flexible and water resistant barrier. 3M EPS-300 tubing is rated for operation at –55°C (–67°F) to 110°C (230°F). Adhesive reflow will occur at temperatures above 80°C (176°F).

3M EPS-300 tubing has a 3:1 shrink ratio. When freely recovered, the tubing will shrink to 33% of its original diameter. The recovered wall thickness of the tubing is proportional to the degree of recovery. 3M EPS-300 tubing offers excellent environmental protection for electronic components, wire splices, wire bundles and harness breakouts. Automotive, truck and marine wire splices and harness breakouts are also quickly and easily protected from a variety of harsh environments.
