3M™ Heat Shrink Tubing FP-301

Flexible, Polyolefin

Data Sheet

July 2010

Description

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).

Agency Approvals &

Self Certifications

Meets requirements of:

• SAE-AMS-DTL-23053/5, Class 1, Class 2 (Clear)*

• AMS-3636, AMS-3637

• UL Recognized, File E-39100, at 600 volts maximum @ 125°C

• CSA Certified, CSA LR38227, at 600 volts maximum @ 125°C

• ABS

*Formerly MIL-I-23053/5 and MIL-DTL-23053/5

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.
