Heat Shrinkable Tubing CB-HFT (3X) / (4X)

Material: Radiation cross-linked modified polyolefin material

Contraction ratio: 2:1 3:1 4:1

Features:

  • halogen-free environment, low smoke, the product complies “RoHS”, “REACH”, “SONY” environmental standards.
  • soft, flexible
  • Products meet UL224 VW-1 flammability rating and F-mark certified flammability rating.
  • products through the UL125 ℃ (E180908) certified.
  • Excellent insulation, heat resistance and voltage performance.

CB-HFT(3X) and CB-HFT(4X) has the same property as CB-HFT type, they are used for protection and marking of special shaped objects, such as wire terminations and electrical connections, cables and electronics components.
