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 adhesi ve.

The heat-shrinkable oute r wall is selectively cross-linked, while maintaining the high

flow and excellent adhesio n 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 &

Self Certifications

• UL Recognized (all colors except clear), UL File E-157227 at 600 Volts and

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 harne ss 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 -55º C (-67ºF) to 110ºC (230ºF), with a

shrinking temperatu re minimum of 121ºC (250ºF).
