Complex product in sheet utilizavel for coating surface of molded structures and process for its apply

摘要

The invention concerns a sheet complex useful for surface coating of structures moulded by low pressure injection, said complex consisting of a planar structure designed to constitute the final element skin, combined with an underlayer designed to adhere with the injected substance, the moulded structure/complex combination being produced during the injection phase itself. The invention is characterised in that the underlayer constituting said structure (9) reverse side is made up of a film based on a thermoplastic composition selected among the polyolefin family, resistant to a temperature higher than the injecting temperature, and forming a thermal barrier during the injecting phase and an adhesive coating with the injected substance.
