3M Heat Shrink Tubing FP-301
Flexible, Polyolefin
Data Sheet July 2010
Description
3M™ Heat Shrink Tubing FP-301 offe rs an outstanding balance of electrical,
physical and chemical properties for a wide variety of industrial and military
applications. Rated for 135°C continuous ope ration, all FP-301 tubing is split
resistant, mechanically tough, easily marke d and resists cold flow.
FP-301 tubing is rated for contin uous operation at -55°C (-67°F ) to 135° C (275°F),
and is designed to withsta nd elevated temperatures to 300°C (57 2°F) for short
periods. Minimum shrin k tempe rature for all FP-3 01 tubing is 100°C (212°F ).

Applications
FP-301 tubing is typically used as a shrink-fit electri cal insulation over cable splices
and terminations. It is also used fo r lightweight wire harness covering, wire
marking, wire bundling, compone nt 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 re covered wall thickness is
proportional to the degree of recovery.
