3M Heat Shrink Tubing EPS-300
Adhesive-Lined, 3:1, Flexible, Polyolefin
Data Sheet

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).

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.
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).
