TGWJ3800 B1 grade silane cross-linked insulating material for wire distribution, specifically design
This product is mainly applied to the insulation of fabric wires with high flame retardant requirements of GB31247 B1 grade. 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.
