The structure of the cam lock panel (eccentric hook type) is a polyurethane sandwich panel made with traditional molds. The eccentric hook is embedded in the mould around the sandwich panel during production, allowing for convenient assembly. It is generally applicable to small or medium-sized cold storage.
The core material of the PUR insulation panel is produced by reacting polyisocyanate with polyether or polyester polyols in specific proportions. These panels feature superior heat conductivity, water absorption resistance, and excellent compressive strength, ensuring they remain resistant to deformation.
