3M™ Heat Shrink Tubing FP-301
Flexible, Polyolefin
Data Sheet
Description
July 2010
3M™ Heat Shrink Tubing FP-301 offers an outstanding balance of electrical,
physical and chemical properties for a wide variety of industrial and military
applications. Rated for 135°C continuous operation, all FP-301 tubing is split
resistant, mechanically tough, easily marked and resists cold flow.
FP-301 tubing is rated for continuous operation at -55°C (-67°F) to 135°C (275°F),
and is designed to withstand elevated temperatures to 300°C (572°F) for short
periods. Minimum shrink temperature for all FP-301 tubing is 100°C (212°F).

Applications
FP-301 tubing is typically used as a shrink-fit electrical insulation over cable splices
and terminations. It is also used for lightweight wire harness covering, wire
marking, wire bundling, component packaging and fire-resistant covering.
Shrink Ratio
FP-301 tubing has a 2:1 shrink ratio. When freely recovered, the tubing will shrink
to 50% of its as-supplied internal diameter. The recovered wall thickness is
proportional to the degree of recovery.
