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 135C 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 -55C (-67F) to 135C (275F), and is designed to withstand elevated temperatures to 300C (572F) for short periods. Minimum shrink temperature for all FP-301 tubing is 100C (212F). Agency Approvals & Meets requirements of: Self Certifications SAE-AMS-DTL-23053/5, Class 1, Class 2 (Clear)* AMS-3636, AMS-3637 UL Recognized, File E-39100, at 600 volts maximum 125C CSA Certified, CSA LR38227, at 600 volts maximum 125C 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.
