Product Description
3M Thin-Wall Heat Shrink Tubing EPS-300 is a 3:1 shrink ratio, dual-wall, flexible tubing with integral, adhesive-lined construction. Made from flame-retardant, flexible polyolefin with an internal layer of special thermoplastic adhesive, its heat-shrinkable outer wall is selectively cross-linked, helping it to maintain the high flow and excellent adhesion of the inner sealant liner. When heated in excess of 121 ºC (250 ºF), this tubing rapidly shrinks to a skintight fit, forcing the melted adhesive lining to flow and cover the substrate, including a wide variety of rubbers, plastics, and metals. Upon cooling, 3M Thin-Wall Heat Shrink Tubing EPS-300's adhesive solidifies, forming a permanent, non-drying, flexible, and water-resistant barrier, with adhesive reflow occurring at temperatures above 80 ºC (176 ºF).
