2 Product Features
Excellent insulation performance
The thermal conductivity is between 0.019-0.022w/m·k, which is the lowest thermal conductivity in the current practical application of thermal insulation materials. Using high pressure continuous foaming technology, the foam is uniform and dense, the cell density is up to 200,000 /cm³, the closed cell rate is up to 97%, and the water absorption is very low, which can effectively prevent the infiltration of water vapor, so as to play its excellent thermal insulation performance.
Good fire resistance
Polyurethane foam has excellent fire resistance, forming a coking protective layer during combustion, which will not melt and drip like EPS and XPS. The flame retardant property can be further improved by combining with metal surface material. Combustion performance reached the national standard 8624-2012 B1 level.
Leading pentane technology
Using non-fluorinated raw materials for one-time high-pressure foaming, no chlorofluorocarbons, room temperature effect is 0, no pollution to the environment, Conform to the international convention on the ozone layer and European environmental standards.
Proprietary airtight technology
Using proprietary airtight structure technology makes the adjacent plate joint insulation layer more organically integrated into one, natural, eliminate "cold steam bridge", greatly improve the airtight performance, more suitable for air conditioning warehouse.
Energy saving, consumption reduction and environmental protection
The selection and processing of polyurethane board strictly follow the national and industry environmental standards, and the board is not easy to breed bacteria and parasites during use, which ADAPTS to various complex situations and stringent environmental requirements in the cold chain industry. The cold storage insulation system of the proprietary plate airtight structure technology connects the cold storage body organically, realizes absolute airtight, saves energy consumption by 30%, and greatly reduces operating costs.
Easy and quick installation
Plate factory prefabricated, installation system design mature, meet the all-weather construction needs, shorten the installation cycle, reduce labor costs and material loss.

The data shown in the left table are only available for the panel which subject to the internal-external pressure difference and contraction pressure, without wind load. If the specified length/height is exceeded or wind load occurs, panel supporters are required.
The above data are calculated according to the heat flow of 8~10W/m2.
