3M Heat Shrink Tubing FP-301VW
Flexible, Polyolefin
Data Sheet July 2010
Description 3M Heat Shrink Tubing FP-301VW has the same outstanding balance of
electrical, physical and chemical properties as FP-301 tubing, and is specially
engineered for excellent flame resistance.
FP-301VW 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-301VW tubing is 100C
(212F).
Agency Approvals & Meets requirements of:
Self Certifications
MIL-DTL-23053/5, Class 3
UL Recognized, File E-39100, vw-1 and E-69751 at 600 volts maximum @
125C
CSA Certified, CSA LR38227, OFT at 600 volts maximum @ 125C
FP-301VW tubing is ideal for fire-resistant coverings of components and flammable
Applications
wire assemblies.
Shrink Ratio FP-301VW 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. High expansion ratios available subject to
factory quotation.
