The main focus of this paper is to introduce novel developments in adhering thermoplastic elastomers onto rigid thermoplastics such as polycarbonate, ABS and their alloys, polyacetal and polyamide. In addition, various rigid thermoplastics can have reinforcements and/or additives, such as fillers and fibers or color masterbatches, which not only can alter the resultant properties of the substrate, but also the surface chemistry.
