Product description
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. Fabricated from
polyvinylidene uoride, the tubing has
outstanding abrasion resistance and cut-
through properties in combination with
high dielectric strength. It is inherently
ame retardant, semi-rigid and highly
resistant to most industrial fuels,
chemicals and solvents. When heated in
excess of 175°C (347°F), MFP tubing
rapidly shrinks to a skintight t. This
tubing is rated for continuous operation
from –55°C (–67°F) to 175°C (347°F).
Typical applications
MFP tubing is designed for shrink-t
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 identication 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.
Standard color
Clear. Colors available subject to
factory quotation.
Standard packaging
Four-foot lengths.
Ordering information
Order MFP tubing by product name,
size equivalent to the expanded inside
diameter, package type and color. Always
order the largest size that will shrink
snugly over the item to be covered.
Example: MFP tubing, 3/8", 4 ft., clear.
