        K-2 flame-retardant polyolefin tubing

        K-2 flame-retardant polyolefin tubing

        KOSOO K-2 is environment friendly, flexible, flame-retardant, irradiated crosslinking heat-shrinkable modified polyolefin tubing. Unlike other typical flame-retarant tubings, K-2 is 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. This high-reliability product is widely used for insulation or jacketing of wire harness, strain relief of wire terminations and connections, bundling of wire harness, protection of soldered points, insulation and capsule of electronic components, anti-corrosive protection, identification and color coding, etc
         

        • Features/Benefits

        ·Shrink ratio: 2:1.

        ·Very flexible, highly flame-retardant.

        ·Low shrink temperature.

        ·Good thermal stability.

        ·Excellent physical, chemical and electrical properties.

        ·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.

        ·Wide range of sizes and colors.
