Such products can be obtained by pouring heated modified polymer into different moulds. To obtain products with specific properties these polymers can be mixed with different fillers beforehand. In particular, to obtain current conducting products mixed with graphite or metal powders; to obtain harder products polymers can be mixed with Granite(Giallo Farfalla) fine powder, asbestos, titanium dioxide or with other fillers. Besides, to obtain new polymer Materials(Tiger Yellow) possessing specific properties polymer mixtures comprising different modified polymers can be used when manufacturing different products: polymethylmethacrylate polystyrene, polymethylmethacrylate polyvinylacetate, polystyrene polyvinyl acetate.
