METHOD FOR MAKING A GLASS MAT AND RESULTING PRODUCT

摘要

A method for making a glass yarn mat, wherein a binder is continuously deposited on a mat of glass yarns spread over a moving conveyor, and the mat is baked and optionally calendered. For this purpose, a liquid binder with a viscosity on deposition of less than around 40 millipascals per second is deposited on the yarn mat, and said binder consists of an aqueous solution of one or more polyvinyl alcohols.
