LOW DENSITY NON-WOVEN MATERIAL USEFUL WITH ACOUSTIC CEILING TILE PRODUCTS |
摘要 |
A non-woven material, that can be formed into an acoustic ceiling tile, is provided. The material includes a substantially planar and self-supporting core of an inorganic base fiber and a synthetic thermal bonding fiber. The synthetic thermal bonding fiber preferably has an increased bonding surface area that improves adhesion and porosity to provide a base mat or core with a low density to provide sound absorption required by an acoustic ceiling tile. |
