Cam-lock PU panel: 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 mold around the sandwich panel during production, allowing for convenient assembly. It is generally applicable to small or medium-sized cold storage.
PU cold storage room panel is a type of board used for enclosing structures, offering excellent heat insulation and high intensity. It reduces heat transmission caused by internal and external temperature differences, maximizing the efficiency of freezing and refrigeration systems. Designed scientifically and easy to use, it is a cost-effective heat insulation material available in multiple varieties and specifications.
Fast-fit PUR panel: The core material of PUR insulation panel is a product of polyisocyanate and polyether or polyester type polyol. Features include good heat conductivity, great water absorption, excellent temperature preservation, and high compressive strength. It is widely used in cold storage structures due to its resistance to deformation.
