Grayline's AL4X is a dual-wall, flexible, heat-shrinkable polyolefin tubing designed for applications requiring robust environmental protection. This product features a thick adhesive lining and a 4:1 shrink ratio. When exposed to heat, the outer wall rapidly contracts while the adhesive inner layer melts and flows, creating a permanent, watertight seal. AL4X offers effective insulation and protection for various industrial and commercial applications, particularly in situations where moisture resistance is critical. The high shrink ratio allows for versatile use across different component sizes, providing manufacturers with a reliable solution for wire and cable management in challenging environments.
