Document Type and Number:
WIPO Patent Application WO/2021/049274
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a mat material wherefrom scattering of inorganic fibers can be prevented, and wherein the surface pressure during use does not drop readily. A mat agent according to the present invention is a mat material comprising inorganic fibers, characterized in that the mat material includes a fiber scattering prevention agent containing a water-soluble polymer, wherein the proportion in weight of the water-soluble polymer over the mat material (water-soluble polymer weight/mat material weight) is 3.0% by weight or less, and the water-soluble polymer is solid at room temperature and does not melt at 300°C.
