2:1 Irradiated Polyolefin Heat Shrinkable Tubing

2:1 Irradiated Polyolefin Heat Shrinkable Tubing for Commercial Applications

Polyolefin shrink tubing is a highly flame resistant and extremely flexible tubing suitable for use with wire and cable assemblies or as component coverage. They are used in applications where substrates are sensitive to heat, and costs can be saved due to reduced shrink time. They are also suitable for applications that require wires and cables that are flame retardant. They can be used in applications such as cables, connectors, and automated cutting machines. At Flex Wires, we provide heat shrinkable tubing to meet the growing demanding of polyolefin tubing.
