3M Heat Shrink Tubing MFP Modified Polyvinylidene Fluoride Data Sheet September 2013 TM Description 3M Heat Shrink Tubing MFP is a cross-linked, thin-walled, heat-shrinkable tubing offering a high degree of mechanical strength and high-temperature resistance. Fabricated from polyvinylidene fluoride, the tubing has outstanding abrasion resistance and cut-through properties in combination with high dielectric strength. It is inherently flame retardant, semi-rigid and highly resistant to most industrial fuels, chemicals and solvents. When heated in excess of 347F (175C), MFP tubing rapidly shrinks to a skintight fit. Agency Approvals & Meets requirements of: Self Certifications SAE-AMS-DTL-23053/8 and functional requirements of 23053/18, Class 1* AMS-3632 UL Listed, UL File E-39100, VW-1 CSA LR38227, OFT *Formerly: MIL-I-23053/8 and MIL-DTL-23053/8 MIL-I-23053/18 and MIL-DTL-23053/18 Applications MFP tubing is typically used for shrink-fit protection and strain relief of wires, solder joints, terminals and connections. Suggested applications include automotive wiring, jackets, fuse coverings and military wire markers. Because the tubing is transparent, it allows see-through inspection and identification, and is ideal for use as a jacketing for components such as resistors and capacitors. The tubing is readily marked by hot-stamp and print-wheel equipment. Shrink Ratio MFP 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. The operating temperature range is from -55C (-67F) to 175C (347F ), with a shrinking temperature minimum of 175C (347F) 1 of 3 3 3M Heat Shrink Tubing MFP Standard Sizes and Dimensions Ordering Expanded I.D.
