KOSOO K-2(3X)
Flexible, flame-retardant, high-shrink-ratio polyolefin tubing
n Application
KOSOO K-2 (3X) is flexible, flame-retardant, high-shrink-ratio irradiated crosslinking heat-shrinkable modified polyolefin tubing. K-2(3X) has 3:1 shrink ratio which is needed to cover larger size differences like harnesses with installed connectors. It is used for insulation protection, bundling or capsule of wire terminals and components with larger size differences.
n Features/Benefits
¡¤Shrink ratio: 3:1.
¡¤Flexible, highly flame-retardant.
¡¤Excellent physical, chemical and electrical properties and high reliability.
¡¤Abrasion and fluids resistance.
¡¤Free of PCBs, PCPs, polybrominated biphenyls (PBBs), polybrominated biphenyl oxides and ethers (PBBOs, PBBEs and PBDEs) and toxic heavy metal compounds, which are classified as environmentally hazardous substances. Conform to European RoHS environmental directive.
