Polyurethane cold storage thermal insulation board is available in various thicknesses, typically 50MM, 75MM, 100MM, 120MM, 150MM, 200MM, 250MM, and 300MM, among others. However, the length and width of the insulation boards can be customized according to the customer's specific requirements. Generally, polyurethane black and white materials are mixed in a certain proportion on-site and then foamed into pre-molded molds using high-pressure equipment.
