PU (polyurethane) coated fiberglass cloth is a common fireproof and thermal insulation material. PU (polyurethane) coated fiberglass fabric is based on high-strength glass fiber cloth, and then coated with a specially formulated polyurethane solution on both sides or one side of the base cloth. The glass fiber cloth without any treatment will produce an itchy sensation on human skin, and the surface hairiness will be uneven. So apply PU (polyurethane) solution on the surface of the glass fiber cloth, and then dry it on a professional coated glass fiber cloth dryer to form a PU (polyurethane) coated fabric. The PU coated glass fiber cloth improves the shortcomings of the glass fiber cloth that it irritates the human skin, and makes the surface of the glass fiber cloth smooth. PU coated fiberglass cloth has many advantages, such as abrasion resistance, waterproof, fireproof, softness, oil resistance, high strength, light weight, easy to carry, easy to cut and sew. The fiberglass cloth can withstand a high temperature of 550 degrees, and the PU coating can withstand a high temperature of 180 degrees. In general, the highest temperature of the PU coated glass cloth is 550 degrees. PU coated fiberglass cloth is often used for fire protection and heat insulation, such as fire curtains, smoke curtains, fire blankets, welding blankets, fabric air distribution ducts, flexible duct connector, detachable insulation sleeves, exhaust pipe insulation sleeves, rubber-plastic insulation board facing.
Generally speaking, the price of PU-coated cloth is cheaper than that of silicone cloth, so if your project does not require so high fire performance, you can choose this economical PU coated fire-resistant cloth. PU coated fiberglass cloth and silicone cloth are almost difficult to distinguish in appearance, but if we observe carefully, we will find that the surface of the silicone cloth is rich in glue and light, while the surface of PU-coated fiberglass cloth is not rich in glue. In addition, the elasticity of silicone cloth is better than that of PU coated fiberglass fabric, so from these two points, we can easily distinguish the two kinds of cloth. Suntex manufacturer can provide single-sided/double-sided polyurethane coated fabric in a variety of colors and widths, and can also be customized.
