3 M. CP-221 Tubing, rated at 125°C
(257°F), is mechanically tough and
provides an economical combination of
electrical insulation, flame retardance and
chemical properties. In comparison with
vinyl tubings, CP-221 Tubing off e r s
higher continuous operating temperature,
reduced longitudinal shrinkage, extended
shelf-life and superior conformity
c h a r a c t e r i s t i c s .

CP-221 Tubing is rated for
continuous operation from –55°C
(–67°F) to 135°C (257°F) and withstands
higher temperatures for short periods. It
is available in standard sizes from 3/64inch
to 2-inch expanded diameter and is
readily markable. Minimum shrink
temperature for CP-221 Tubing is 121°C
( 2 5 0 ° F ) .

Standard Sizes and Dimensions

Typical Applications

CP-221 Tubing is recommended as a
general purpose heat-shrinkable tubing
for new commercial applications as well
as for upgrading existing applications
where other types of tubings are now
used.

Shrink Ratio

CP-221 Tubing has a 2:1 shrink ratio.
When freely recovered, the tubing will
shrink to 50% of its as-supplied internal
d i a m e t e r. The recovered wall thickness of
the tubing is proportional to the degree of
r e c o v e r y. High expansion-ratio CP-221
Tubing is available subject to factory
