Multi size widely used kosoo ultra thin-wall flame-retardant polyolefin tubing heat shrink tube
KOSOO K-2(CB)
2:1 Ultra Thin Wall Heat Shrink Tubing
KOSOO K-2 (CB) is environment friendly, ultra thin-wall, flexible, flame-retardant, irradiated crosslinking heat-shrinkable modified polyolefin tubing. It is designed for applications that require an ultra thin wall for rapid shrinking and space saving. Low shrink temperature further reduces installation time and the risk of damage to temperature-sensitive components.
Features/Benefits
·Shrink ratio: 2:1
·Low shrink temperature.
·Ultra thin-wall, rapid shrinking.
