3:1 Very Flexible Polyolefin 
Data Sheet

Product Description

3 M. S F T W-203 is a 3:1 shrink ratio 
tubing that offers an outstanding balance 
of electrical, physical and chemical 
properties for a wide variety of industrial 
and military applications. SFTW-203 is 
made of very flexible, heat-shrinkable 
polyolefin which is mechanically tough, 
chemically resistant, and can be easily 
surface printed.

S F T W-203 tubing has been 
engineered to offer a low shrink 
temperature of 100°C (212°F). T h i s 
allows the tubing to shrink rapidly, and 
minimizes heat exposure and possible 
damage to temperature sensitive 
s u b s t r a t e s .

S F T W-203 tubing meets the 
performance requirements of MIL-DTL23053/
5 Class 1, and is ULR e c o g n i z e d 
(File No. E48398) for flame retardance. 
It is rated for continuous operation from 
-55°C (-67°F) to 135°C (275°F), and 
withstands elevated temperatures of 
300°C (572°F) for brief periods.

Standard Sizes and Dimensions

Typical Applications

The extra flexibility and low shrink 
temperature of SFTW-203 tubing make it 
ideal for shrink-fit jacketing and 
insulation of flexible wire bundles and 
temperature sensitive components. T h e

3:1 shrink ratio makes SFTW-203 the 
insulation of choice for end terminations 
where the connector body is larger than 
the cable and for repair applications 
where the tubing must be slid over a 
c o n n e c t o r. SFTW-203 can also be used 
to insulate an oversized component in 
line to the wiring. 
Shrink Ratio

S F T W-203 has a 3:1 shrink ratio. W h e n 
freely recovered, the tubing will shrink to 
33% of its as-supplied internal diameter. 
The recovered wall thickness of the 
tubing is proportional to the degree of 
r e c o v e r y.

Ordering Information

Order SFTW-203 by product name, size 
equivalent to expanded inner diameter, 
c o l o r, and package type. Always order 
the largest size that will shrink-fit snugly 
over the item to be covered.
