摘要

The system of comipu00f3sito in layer, the process for securing one or more layers of a foam of open cell, based on a amiinoplasto to a substrate or produce a system of composite layer, and uses of the system of composito in layer, and the use of one or more layers of foam cell. Open on the basis of a aminoplasto.A system of composite layer which comprises one or more layers) of a foam of open cell, based on a aminoplasto and one or more layers (b) of non fibrous tissue or fibrous tissue, in which the said layer (b) comprises fiber of melanin, their production and use as a sponge Cleaning or subcamada protective.
