Abstract: A molded article such as a floor tile is made from recycled carpet waste which includes a polyvinyl chloride component in the backing material and fiber component having a melting point above the melting point of polyvinyl chloride. A mixture of the recycled carpet material is shredded and additional polyvinyl chloride is fed to an extruder where the polyvinyl chloride is melted without melting the carpet fibers. The resulting mixture is discharged and molded, such as by injection molding, to form a molded product. The molded product includes a continuous matrix of polyvinyl chloride having recycled carpet fibers uniformly dispersed therein. The molded article contains about 45% to about 85% of polyvinyl chloride, about 5% to about 20% of recycled carpet fibers, up to about 5% of a plasticizer and up to about 5% of an ethylene copolymer by weight based on the total weight of the product.

Abstract: A method of recycling spent filter media is disclosed. The method can include providing a cloth, the cloth being spent polymer-base filter media, removing foreign solid particles from the cloth, washing the cloth, drying the cloth and processing the dried cloth to produce polymer-base particles that can be used to produce a component. The processing of the dried cloth can include densifying and/or granulating the dried cloth. In addition, the spent cloth can have been used as metal working filtration media and the foreign solid particles removed from the cloth using a brush. In some instances, the cloth is washed using a dry cleaning process and the granulating or densifying of the cloth produces particles that can be used in an injection molding machine.

Abstract: A front cover, a rear cover and a base portion are crushed into a crushed material, and further pelletized into a recycled plastic pellet. The recycled plastic pellet is used as a part of a molding material to produce mold plastic parts for a photosensitive material. When the molding material is melt in heat, a thermoplastic resin is deteriorated by heat or modified. Therefore, properties and qualities of recycled plastic mold parts are less than those of new ones. Further, when the thermoplastic resin is deteriorated by heat, the photosensitive material reacts with the thermoplastic resin to decomposed products having an bad influence on photographic characteristics. In order to prevent the deterioration by heat, oxidation inhibiting materials are added, and in order to absorb the decomposed products, carbon blacks are added.

Abstract: Synthetic roofing products such as simulated slate and clay tile shingles, and other products, such as flower pots, floor coverings, plastic pallets and the like are compression molded from a mixture of ultra low density polyethylene binder and a filler which may comprise recycled rubber products such as E.D.P.M (ethylene propylene diene monomer) and S.B.R. (styrene butadiene rubber). Colorants may be added to the mixture prior to final molding. Many of the products, especially synthetic shingles, are less expensive, easier to handle, and more durable than the slate or clay tile shingle product simulated.

Abstract: This invention relates to articles made of polyester, preferably polyethylene terephthalate (PET), having coated directly to at least one of the surfaces thereof one or more layers of thermoplastic material with good gas-barrier characteristics, and novel methods of making such articles. Preferably the barrier-coated articles take the form of preforms coated by at least one layer of barrier material and the containers blow-molded therefrom.

The materials and methods provide that the barrier layers have good adherence to PET, even during and after the blow molding process to form containers from preforms. Preferred barrier coating materials include poly(hydroxyamino ethers).
