3MTM Heat Shrink Tubing EPS-300 Adhesive-Lined, 3:1, Flexible, Polyolefin Data Sheet Description November 2018 3MTM 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 flameretardant, 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 121C (250F), 3M 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 80C (176F). Agency Approvals & Self Certifications * UL Recognized (all colors except clear), UL File E-157227 at 600 Volts and 125C maximum * CSA Recognized, CSA File LR38227 * For RoHS and REACH information, please visit www.3M.com/regs Applications 3M 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 3M 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 -55C (-67F) to 110C (230F), with a shrinking temperature minimum of 121C (250F). 1 of 3 3MTM Heat Shrink Tubing EPS-300 Typical Properties Not for specifications.
