Features
- 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
- 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 recovery
- Inert fungus resistance
- Non-corrosive chemical effect
- No dripping, flowing or cracking (4 hr at 250 °C) of heat shock
- Self-extinguishing
- Low Temperature Flexibility: -55 °C
- Temperature Rating: -55 to 135 °C
Applications
- Ideal for Shrink-Fit Jacketing and Insulation of Flexible Wire Bundles and Temperature Sensitive Components
- Can also be Used to Insulate An Oversized Component in Line to the Wiring
