Our newly developed insulating boards are used in metal smelting electrolytic systems, providing insulation and barrier functions for copper rods and bars. They feature high processing precision, with bending deformation ≤1mm in the 5-meter length direction. Moreover, due to the use of high-performance vinyl resin and glass fiber materials, the products also boast high strength and corrosion resistance, meeting industry standards. Customized processing according to customer requirements is available.
