 FEP
Heat Shrink
Tubing
Zeus
fluoropolymer
heat shrink provides the ideal method for the application of a tight, protective jacketing to items that ultimately will be subjected to extremes of heat, corrosion, shock, moisture, or other critical environmental conditions.
The application
of heat shrink
tubing extends
the life of such
items
indefinitely,
and assures
their reliable
performance.
Zeus heat shrink
tubing is used
successfully in areas such as the aerospace, electrical, chemical, optical, medical, nuclear, and automotive fields.
Zeus offers a unique combination of properties in
fluoropolymer
heat shrink tubing, including high strength, outstanding electrical characteristics, excellent chemical and solvent resistance, purity, uniformity, lubricity, shock and abrasion resistance, and reliable operational performance up to and exceeding 500°F.
Our products conform to both military and commercial standards and in most cases exceed the intent of these standards.
FEP heat shrink
tubing in
particular is
chosen for its
lower shrink
temperature than
PTFE, greater
flexibility,
optical clarity,
and high
lubricity in
comparison to
PFA.
Zeus heat shrink
tubing
products are provided in the expanded state. With the brief application of heat, they mold themselves snugly around the most intricate and irregular shapes to form a completely sealed covering
(see our
heat shrink
recovery
information). Sources of heat and methods of heating are optional.
Please contact
your Zeus
Technical
Account Manager
for guidance on
the optimal heat
shrinking
process.

Shrink
Ratios
Zeus FEP heat shrink tubing is available with shrink ratios of 1.3:1 and 1.6:1 or greater incorporating all the same high standards and characteristics
of FEP. Micro-miniature dimensions are also available.

and tolerances
quoted upon
request.
Heat
Shrinking
Guidelines for
FEP Heat Shrink
Tubing
- Always assure good ventilation in the immediate work area prior to beginning the heat shrink process. Caution: Fumes may cause nausea and dizziness.
- Heat
shrink FEP
tubing requires
approximately
420°F
+/-
50°F
(215°C
+/-
10°C).
This is
a
liberal
and safe
range.
Please
keep in
mind
that
these
temperatures
are
approximate.
Actual
shrink
temperatures
will
vary
based on
the
dimensions
and wall
thickness
of the
tubing,
application
techniques,
and
other
factors.
Zeus is
happy to
provide
samples
to test
in your
application
to
determine
the best
material
to use.
- The mandrel (part) to be covered by
heat shrink FEP must be able to withstand this range of temperature.
- Zeus recommends preheating larger diameter mandrels.
- Heat
shrink FEP needs only a small degree of recovery. You may experience
some
slight
longitudinal change
depending on the amount of recovery.
Contact
Zeus if
longitudinal
change
is a
concern.
- Even heating of all sides and even cooling of all sides provides the best results. Uneven heating or cooling tends to split the side still in the "gel" state while the other side is in the hard or crystalline state - especially upon recovery.
NOTE: Shrink starts when the FEP is brought up to the "gel" state but completes its recovery during the cooling cycle.
In its gel state the tubing becomes crystal clear and glassy in appearance.
-
Ovens
are the
most
reliable
way to
recover
heat
shrink
products
due to
their
ability
to
ensure
even
heating
and
reduce
the risk
of over
heating
the
material
(which
can lead
to
brittleness
and
cracking).
If a
heat gun
will be
used,
please
contact
Zeus for
tips on
proper
application
of heat
to
achieve
the most
uniform
recovery.
