(1) For various shapes of substrates, whether they are flat, vertical, or top surfaces, whether they are circular, spherical, or other irregularly shaped complex objects, spray foaming processing can be directly implemented without expensive mold manufacturing costs;

(2) The shape of the foam thermal insulation layer formed by spraying foaming is consistent with the shape of the substrate object; No seams, good insulation effect; There is a dense protective layer outside the foam layer, which can better protect the internal core material, and it is also easy to paint and further repair the external surface;

(3) High production efficiency, especially suitable for insulation treatment of large and irregular objects, with fast molding speed and high production efficiency.

(4) Adhesive strength: Strong adhesive ability, able to firmly bond on surfaces such as concrete, bricks, wood, steel, asphalt, rubber, etc;

(5) Thermal conductivity: can reach 0.017-0.022W/m.k, lower than building insulation materials such as rock wool, glass wool, polystyrene board, extruded polystyrene board, etc;

(6) Hydrophobic performance: Hydrophobic rate of over 95%;

(7) Sealing performance: No cavities or seams, completely enveloping the building envelope structure, effectively preventing wind and moisture from flowing in and out of the building through gaps, achieving complete sealing;

(8) Dimensional stability: Dimensional stability is less than 1%, with a certain degree of elastic deformation ability, and elongation greater than 5%;

(9) Constant performance: Polyurethane is an inert material that does not react with acids or bases, and is not a food source for insects or rodents. It can maintain constant material properties and insulation performance;

(10) Wind resistance performance: compressive strength>300Kpa, tensile strength>400Kpa, strong wind resistance, and its foam can penetrate into wall gaps, increasing its shear resistance
