125-degree silane cross-linked insulating material TGWJ2200-25 for wire distribution, 125-degree sin
This product is mainly applied to fabric wires with the requirement of single vertical burning. 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.
