Article and manufacturing process for article having individual material properties

A process for biaxially and triaxially blow molding an integrated article by forming different portions of the resultant article from different materials having individual material properties such as thermal and chemical resistance, magnetic properties, electrical resistance/conductance, mechanical abrasion resistance, catalytically active surface and other material properties, the process comprising:

• forming a continuous parison including at least two polymeric resinous materials with a filler material in at least one of the polymeric resinous materials incorporated therein, directing at least one extrusion nozzle carrying a first material to a die head, and directing at least one more extrusion nozzle carrying a second material to the same die head, said parison having a length and a circumference to be blow molded into resultant articles;
• extruding the at least two materials from the die head said at least two materials being selected from the group consisting of polyesters, polypropylene, polyethylene, polyester terphthalate, butadiene-styrene co-polymers, polyamides, ethylene-vinyl-alcohol copolymer, polyethylene napthaphthalate, thermoplastic and thermosetting resins, polybutylene terephthalate, polyoxymethylenes, polycarb-onates, polyphenylene, polyphenylene sulfides, polyphenylene oxides, polymethylmethacrylate, polyethylene-terephthalate, polyvinylidenechloride, polymethylpentene-1, nylon 6, nylon 66, and mixtures thereof;
• mixing filler materials into at least one of the two polymeric resinous materials being extruded such that various materials having individual material properties become incorporated into the resultant article at various locations along the length and circumference of the parison so that those various properties are formed into the article where the properties are needed, the filler materials being selected from the group consisting of all naturally occurring and all manufactured ceramics selected from the group consisting of silicon nitride, silicon carbide, alumina, boron, carbide, tungsten carbide, carbides, nitrides and oxides of various metals to be chosen for their various properties, kaolin, cordierite, mullite, metal flakes, iron filings, steel chips, magnetic filings, magnetic particles, surface enhancing metal particulates, pulverized road construction particulates, stone chips, crushed slag, crushed concrete, cracked and crushed heavy road tars, crumbed rubber tires, densified foam chips, recycled materials to be used as filler and property enhancers, fibers from cardboard/paper products, crumbed soda pop bottles and glass fiber strength imparting filler materials for reinforcement,
• whereby a fully integrated article of manufacture is formed having individual material properties in desired places within the resultant blow molded article.
