KOSOO K-2(GYS)
Yellow & green striped, flexible, flame-retardant polyolefin tubing
n Application
KOSOO K-2 (GYS) is yellow & green striped, flexible, flame-retardant, irradiated crosslinking heat-shrinkable modified polyolefin tubing. It is designed for use in earth sleeving. 3:1 shrink ratio is for more suitable for application to irregular, awkward shapes.
n Features/Benefits
¡¤Shrink ratio: 2:1, 3:1.
¡¤Flexible, flame-retardant.
¡¤Excellent physical, chemical and electrical properties and high reliability.
¡¤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.
