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. - 3M™ heat shrink tubing LMFP is a cross-linked, thin-walled, heat-shrinkable tubing offering a high degree of mechanical strength and high temperature resistance. When heated in excess of 347 °F (175 °C), MFP tubing rapidly shrinks to a skintight fit.
