™ 3M Heat Shrink Tubing EPS-300 Adhesive-Lined, 3:1, Flexible, Polyolefin Data Sheet August 2011 Description 3M™ Heat Shrink Tubing EPS-300 is a 3:1 thin-wall, flexible tubing offering the advantages of integral, adhesive-lined 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 maintaining the high flow and excellent adhesion of the inner sealant liner. When heated in excess of 121ºC (250ºF), EPS-300 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). Agency Approvals & • UL Recognized (all colors except clear), UL File E-157227 at 600 Volts and Self Certifications 125ºC maximum • CSA Recognized, CSA File LR38227 Applications EPS-300 tubing offers excellent environmental 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. Shrink Ratio EPS-300 tubing has a 3:1 shrink ratio. When freely recovered, the tubing will shrink 33% of its as-supplied diameter. The recovered wall thickness of the tubing is proportional to the degree of recovery. The operating temperature range is from -55ºC (-67ºF) to 110ºC (230ºF), with a shrinking temperature minimum of 121ºC (250ºF). 3 1 of 3
