This product is mainly applied to the insulation and sheath layers of high-voltage wires in vehicles as per the QC/T1037 standard. The product has a good scratch resistance effect and is suitable for high-voltage wires in vehicles of 10 square meters or less. 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.
