Abstract
A high-relief, resiliently flexible composite molded plastic product (21). The product (21) includes a relatively rigid injection molded core member (22) having a pair of oppositely facing core shoulders (26,27), and a plastic sleeve member (23) with sleeve shoulders (36,37) interengaged with the core shoulders (26,27). The sleeve member (23) is rotationally cast or molded from a plastisol dispersion having emulsion grade polyvinylchloride and suspension grade polyvinylchloride in a ratio of at least 3:1, and preferably 5:1, to produce substantial flexibility and to enable high-relief design features (46) to be molded into the sleeve member (23).
