The NB08192001 is a semiflexible, dual-wall heat-shrinkable tubing from the HTAT series, designed for environmental sealing of various substrates at elevated temperatures. Manufactured from radiation-crosslinked polyolefins, its inner adhesive wall melts and flows during heating while the outer wall shrinks, creating a tough, protective moisture barrier. This tubing features a high 4:1 shrink ratio, operates over a temperature range of -55°C to 125°C, and has a flame-retardant jacket. It is well-suited for applications like connector sealing and protecting irregular shapes with large diameter differences.
