Compression-moulded, multilayer composite product and procedure for producing the same

摘要

A multilayer composite product and a procedure for producing the same. The product has an intermediate layer of organic fibers and has been compression moulded under pressure and at high temperature. It comprises a combination of at least two mineral wool layers (10, 12) and an intermediate layer (14), which is made of an unbleached, unglazed, matted and specially composed paper of long-fibered sulfate pulp. Due to the configuration of the specially composed paper, strong chemical bonds form between the different layers.
