A-level flame retardant/thermal insulation/hydrophobic and moisture-proof
▶  Excellent insulation performance: The thermal conductivity is between 0.019-0.022w/m · k (25 ℃), which is the lowest among the insulation materials currently used in practical applications. Adopting high-pressure continuous foaming technology, the foam is evenly and densely foamed, with a closed cell structure and small cell size. The cell density can reach 200000 cells/cm ³, and the closed cell rate is over 97%. The water absorption rate is extremely low, which can effectively hinder the penetration of water vapor and thus exert its excellent thermal insulation performance.
▶  Excellent fire resistance: Polyurethane rigid foam has excellent fire resistance, and a coking protective layer will be formed during combustion, which will not melt or drip like EPS and XPS. Composite with metal surface material can further improve its flame retardant performance. The combustion performance meets the national standard 8624-2012 B1 level.
▶  Pentane technology is leading: it uses fluorine free raw materials for one-time high-pressure foaming, does not produce fluorocarbons, has zero greenhouse effect, does not pollute the environment, complies with international conventions on the ozone layer, and meets European environmental standards.
▶  Exclusive airtight technology: Using proprietary board type airtight structure technology, adjacent board seam insulation layers are more organically combined into one, seamlessly integrated, eliminating "cold steam bridges" and greatly improving airtight performance, making it more suitable for controlled atmosphere storage.
▶  Energy saving, consumption reducing and environmental protection: The selection and processing of polyurethane boards strictly follow national and industry environmental standards. During use, the board is not prone to bacterial and parasitic growth, making it suitable for various complex situations and strict environmental requirements in the cold chain industry. The cold storage insulation system with proprietary board type airtight structure technology organically connects the cold storage body, achieving absolute airtightness, saving energy consumption by 30%, and greatly reducing operating costs.
▶  Easy and fast installation: The sheet metal is prefabricated in the factory, and the installation system design is mature, meeting the requirements of all-weather construction, shortening the installation cycle, and reducing labor costs and material losses.
