| Product Description Ceramic wool blanket is a high-strength needle-punched insulation blanket made of high-quality kaolin, high-purity alumina and silica, by spinning or blowing combined with needle punching process, to produce a tough, elastic and high-strength blanket, which is not easy to tear before or after heating. It does not contain asbestos and does not add any chemical adhesives. All made by inorganic materials that provides a variety of temperature grades, densities and sizes. It can be folded, compressed and packaged to make modules. |
