Polyurethane coated fibreglass composite fabric, is a non-woven glass fiber yarn for the reinforcement of materials, polyurethane resin being a substrate fabric, through the pultrusion procedure molding. Since fibreglass is a kind of inorganic non-metallic fiber, it provides very good flame retardancy as well as heat opposition, as well as the conventional melting level is far more than 1000 ℃.

Polyurethane material is a thermosetting material, after the fire will form a layer of carbonization layer on the surface, to prevent the flame deep, do not melt, do not produce droplets. Therefore, fiberglass reinforced polyurethane composites are difficult to burn when caught in fire, and the high temperature of the fire surface is difficult to transmit to the other side. High fire resistance makes the function of fiberglass reinforced polyurethane composite profile in protecting the safety of users' life and property greatly improved.

In developed countries in Europe and the United States, construction with polyurethane coated fiberglass total consumption of about 70%, is refrigerators, freezers and other hard foam dosage more than once. In China, the application of hard bubbles in the construction industry is not as common as in the developed countries of the West, so the potential for development is very great.
