3:1 Very Flexible Polyolefin
3M SFTW-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.
SFTW-203 tubing has been engineered to offer a low shrink temperature of 100°C 212°F . This allows the tubing to shrink rapidly, and minimizes heat exposure and possible damage to temperature sensitive substrates.
SFTW-203 tubing meets the performance requirements of MIL-DTL23053/5 Class 1, and is UL Recognized 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.
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. The 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 connector. SFTW-203 can also be used to insulate an oversized component in line to the wiring.
SFTW-203 has a 3:1 shrink ratio. When 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.
Boxes of four-foot lengths, or large spools. Cut pieces subject to factory quotation.
Order SFTW-203 by product name, size equivalent to expanded inner diameter, color, and package type. Always order the largest size that will shrink-fit snugly over the item to be covered. Example SFTW-203, 1/2", black, 4 ft lengths.
