TUV photovoltaic silane cross-linked low smoke zero halogen insulating material TGWJ5000 TUV insulat

This product is mainly applied to the insulation layer of TUV1169 standard photovoltaic cables. The product can meet the requirements of high-speed extrusion production. The product adopts the silane cross-linking process, featuring excellent extrusion fluidity and resistance to pre-cross-linking. Cross-linking can be achieved through natural placement for 3 to 5 days, or it can be quickly cross-linked by steam or water boiling, significantly reducing the time for subsequent processes after the line is formed.
