3M™ Heat Shrink Tubing EPS-400 Adhesive-Lined, 4:1, Semi-Rigid, Polyolefin Data Sheet Description November 2018 3M Heat Shrink Tubing EPS-400 is a medium-wall, semi-rigid 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 the adhesive maintains high flow and excellent adhesion characteristics. When heated in excess of 121ºC (250ºF), EPS-400 tubing rapidly shrinks to a skintight fit, forcing the melted adhesive to flow and cover the substrate. 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 & Self Certifications Meets requirements of: • UL Recognized, UL File E-157227 at 600 Volts and 125 ºC maximum • CSA Recognized, CSA File LR38227 • For RoHS and REACH information, please visit www.3M.com/regs Applications 3M EPS-400 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. Shrink Ratio 3M EPS-400 tubing has a 4:1 shrink ratio. When fully recovered, the tubing will shrink 25% 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 110 ºC (230ºF), with a shrink temperature minimum of 121ºC (250 ºF).
