Recently, environmental concerns have raised recycling awareness and are now considered a design prerequisite for automobiles. However, soft surfaces for interior components have conventionally consisted of polypropylene foam (PPF) laminated polyvinyl chloride (PVC) skin, which was then bonded to a plastic foundation. This layering of disparate materials led to difficulties in recycling these components. Numerous efforts have been made to resolve these issues, including (1) the use of solvent-free adhesives, (2) the development of all olefin instrument panel (l/P) pads and, (3) the recycling to the foundation materials of the olefin skin. This paper presents an outline of a process in which the bottom layer of the bi-laminate is pre-coated with an adhesive for bonding, thereby reducing the pretreatment required for skin and foundation and leading to significant reductions in the number of procedures in the vacuum forming process. Mono-materials are utilized in soft pads for automotive intehor components to ease recycling efforts. Olefin is an example of a mono-material, and olefin instrument panels (i/P) are produced using a vacuum forming method. To simplify the production process for these parts, adhesive spray coating on the surface of the plastic foundation has been replaced by pre-coating on the reverse surface of the laminated skin, enabling the reduction of both adhesive spraying and drying procedures in the forming process. Development of an adhesive with excellent high temperature adhesion performance on olefin has eliminated the necessity for pretreatment of the olefin foundation and the skin (primer treatment and flame treatment). This has enabled a significant reduction in the forming procedures and has rationalized the process.
