The largest size which will recover snugly over the component to be covered
should be ordered.
With TFE-R the maximum outside diameter of the device to be encapsulated should be less than
20% of the minimum expanded inside diameter of the tubing. The wall thickness of the tubing will
be less than specified if recovery is restricted during shrinkage.
Other lengths and sizes are available subject to special order.

High temperature, chemically
inert, heat-shrinkable tubing
Raychem TFE and TFE-R are heat-
shrinkable tubings manufactured from a
modified Teflon
(Polytetrafluoro-
ethylene), an excellent high temperature
covering and insulation material with a
milk-white translucence. TFE is the
general purpose tubing for difficult
chemical and thermal environments. TFE-
R has the added advantages of thin wall,
high shrink ratio, greater flexibility and
transparency in application. TFE and TFE-
R are highly flame retarded and exhibit
outstanding chemical and solvent
resistance with electrical characteristics
which remain stable over a wide
temperature range. The operating
temperature ranges from -67
°C to
+250°C, and up to 400°C for short
periods.
The major uses of these materials are for
electrical insulation, protection of
electronic components and the covering
of hydraulic hose and couplings
preventing contamination and corrosion.
The high mechanical strength and
extremely low coefficient of friction make
it ideal for reducing damage to bearing
shafts, etc.
