1,Description of polyurethane foam board
Polyurethane foam board is a composite board produced by chemical reaction with polyurethane hard foam and cyanate ester as the main raw materials and under the action of catalyst, foaming agent and surfactant. The product has light bulk weight, high strength, antifreeze, heat insulation, flame retardant, anti-corrosion and non water absorption. It has become an indispensable insulation material in the construction industry, refrigeration field, petrochemical industry, electric power and other industries.
Polyurethane foam board is a composite board made of polyurethane hard foam as the core material, covered with non-woven fabric or other finishing layers on both sides or one side. It has high closed cell rate and excellent thermal and cold insulation performance. The 5cm thick product is equivalent to the 1m thick concrete thermal insulation effect. The product is a new material with thermal insulation and waterproof functions, and its thermal conductivity is very low, which is the general of polystyrene foam board. The product can be used in the environment of - 196 ℃ -+150 ℃, and can reach the service life of 30 years.
