Price and sale of polyurethane spray materials
Polyurethane spray foam, which is a type of hard foam, is used to insulate roofs, walls, buildings, pipes, tanks, and chicken farms. Hard polyurethane foams are used as thermal insulation in Various forms such as polyurethane sandwich panels, types of polyurethane coating, thermal insulation of the middle of doors, polyurethane sealant of various types of connections, thermal insulation of cold storage floors and polyurethane spray foam are used. In pre-built buildings, the surface Sections in complex shapes and with non-geometric dimensions, and sometimes polyurethane spray foam is used for lining insulation of interior and exterior decoration of buildings.
Polyurethane spray foam, which is called polyurethane spray foam (SPF) in industrial terms, like other hard polyurethane foams, consists of two components, polyol and isocyanate. One of the components of polyol in this type One of the raw materials of polyurethane is the foaming agent, which is one of the types of chlorofluorocarbon (CFC) gases such as 141B gas. This gas, by evaporating due to the heat resulting from the reaction of polyol and isocyanate, creates closed cell bubbles inside the polyurethane. It creates a spray which is the basis of the properties of this type of foam as thermal insulation.
The reaction speed between polyol and isocyanate in polyurethane spray foams is very high, so that after spraying the mixture of polyol and isocyanate on the target surface (even vertical surfaces and surfaces installed against the direction of gravity and) the polyurethane foam formation reaction started at a high speed (less than 2 seconds after spraying, the foaming reaction starts and in less than 20 seconds, the sprayed polyurethane foam is formed and the foam structure is formed) and high-speed polyurethane spray foam And it is formed without the material falling down and with high adhesion to the surface.
The thickness and density of polyurethane spray foam depends on the type of expected application. The useful life of polyurethane spray foam is at least 10 to 15 years according to environmental factors, and insects and bacteria cannot live and grow in it due to its closed cell nature. Other features of this polyurethane spray foam are its weight. Its bottom is for use on surfaces with low resistance. Also, in order to prevent the fire of this type of foams, according to international standards, self-extinguishing (slow-burning) types of polyurethane spray foam are used.
Some of the applications of polyurethane spray foam are as follows:
