Silane cross-linked low-smoke halogen-free flame-retardant polyolefin cable material is convenient to use, not only can be quickly cross-linked under warm water cooking conditions but also can be naturally placed at room temperature for cross-linking without additional irradiation processing, which makes Silane cross-linked low-smoke halogen-free flame-retardant polyolefin cable material more widely used.
Through the radiation cross-linking process, the wire and cable can achieve the effect of flame retardant UV irradiate LSZH, which is suitable for large-scale and high-efficiency mass production of thin-walled insulation layers of wire and cables.
The Flame retardant grade pass IEC60332 Single vertical cable combustion test and Bunched cables combustion test.
