A composite moulded plastic product (21) which includes a relatively rigid injection moulded core member (22) having a pair of oppositely facing core shoulders (26, 27), and a plastic sleeve member (23) with sleeve shoulders (36, 37) inter-engaged with the core shoulders (26, 27) respectively. The sleeve member (23) is rotationally cast or moulded from a plastisol dispersion having emulsion grade polyvinylchloride and suspension grade polyvinylchloride in the ratio of at least 3 to 1, and preferably 5 to 1, to provide sufficient elasticity for mounting on the core member (22) and to enable high-relief design feature (46) to be formed. The dispersion includes plasticizer (e.g. diisononylphthalate, epoxidized soyabean oil), stabiliser (e.g. a calcium/zinc), catalyst and mould release agent. The product 21 is a cup for coffee, chocolate, tea etc or may be high-relief moulded flexible handles for eating and serving utensils. <IMAGE> |
