Layered sheet and manufacturing process

摘要

The layered sheets obtained as proposed by the invention are formed by two or more substrates, consisting of mixtures of different polyolefins, in their middle (2) or lower (5) layer, and polyolefins with elastomeric composites in the upper or external layers (1) and (4); the performance of the procedure for obtaining the sheets consists of a process of co-extrusion in which mixing is made of the different components giving a product that produces the end pieces by vacuum moulding, pieces that will be applied as interior upholstery for vehicles, providing them with the required acoustic and thermal insulation and a high level of comfort, at the same time as they provide a high level of impermeability that allows for washing.
