The Transformation of Recycled Painted Fascias for use in Automotive Acoustical Applications 1999-01-1678
Substantial activity in the field of recycling has made industry increasingly aware of the need to find novel ways of reusing post industrial and post consumer waste to produce useful products for our markets. The traditional approaches have been to use the scrap material as is into the original markets targeted for virgin materials, and finding areas that can accept the resultant downgraded properties. This approach has created difficulties in the recycling of automotive painted thermoplastic polyolefin (TPO) fascia and trim products. The presence of the paint contaminant has substantially degraded the physical properties of the plastic.
This paper reviews the use of painted TPO scrap as a raw material for automotive sound barrier applications whereby the inherent material characteristics of TPO are capitalized on. The material modifications and functional characteristics as they relate to this application are described. The development approach, target applications, testing results and development opportunities are discussed.
