The invention involves recycling scrap material having a thermoplastic. The invention includes a method of forming a thermoplastic pre-preg sheet for use in a subsequent molding operation. The method includes shredding a first scrap material having a thermoplastic to form fluff. The fluff has at least about 20 percent weight of thermoplastic. The method further includes sufficiently compacting the fluff into a thermoplastic state sufficient for forming the thermoplastic pre-preg sheet.

Method of recycling scrap material containing a thermoplastic

Method of making a shell mold for casting molten metals or alloys involves forming a thermally collapsible, low density reaction injection molded (RIM) thermosetting polyurethane foam pattern having a shape corresponding to the casting to be made. The pattern is formulated to have an aggregate density (pattern outer skin and pattern cellular core) in the range of about 10 to 15 lbs/ft and a smooth continuous as-molded surface devoid of surface connected open cells, dimensional stability over a range of temperatures, and ready, ashless burnout from the shell mold formed thereon without cracking the shell mold. The pattern is free of organometallic catalysts that should not be present in the casting of aerospace superalloys, such as nickel and cobalt base superalloys and titanium. The pattern then is invested without the need for any surface polymer or other film or layer in a shell mold.

Investment casting patterns and method

An article of manufacture for load bearing medical use such as a joint implant suitable for total joint replacement. The article comprises a polyurethane-containing component and is monolithic with respect to polyurethane-containing component(s). The joint for long term load applications is structurally an articulated joint and the polyurethane component provides a surface for articulation with the polyurethane.

Polyurethane and so forth containing joints

A method for recycling materials including a significant portion of polyurethane foam includes forming the foam into a fluff of particle sized 0.25-1.0, and most preferably 0.25-0.50 inch. The material is moved to a mold and molded at an elevated temperature and pressure. Preferably, the glass transition temperature of the foam is exceeded. Other filler materials may be mixed with the fluff material. The invention recycles scrap which includes polyurethane foam, but greatly reduces the complexity of re-utilizing the scrap.

Method of recycling polyurethane foam components

A compressed solid produced from a feed mixture of bottom ash and a binder. The feed mixture includes about 80% to 95% by weight bottom ash, or at least about 50% by weight bottom ash in combination with other waste materials, in combination with a polyisocyanate-based binder.

Solids produced from ash and process for producing the same

Thermoplastic polyurethanes are formed from a hydrogenated polydiene diol having from 1.6 to 2 terminal hydroxyl groups per molecule and a number average molecular weight between 500 and 20,000, an isocyanate having two isocyanate groups per molecule, and optionally a chain extender having two hydroxyl groups per molecule. The thermoplastic polyurethanes have excellent resistance to moisture as evidenced by retention of more than 70%, preferably at least 85%, of original tensile strength after aging in water for 7 days at a temperature of at least 70.degree. C. Preparation by a prepolymer method with subsequent addition of the chain extender is preferred.

Polyurethanes having improved moisture resistance

The invention relates to a method for the recycling of trim components of vehicles. The method comprises the steps of shredding manufacturing scrap and post-consumer scrap from vehicle headliners into small particles to produce fluff. This fluff is then combined with water and a binder reagent composed of either polyisocyanates, or polyisocyanates combined with various polyols. The solution of fluff, binder reagent and water are mixed, and then placed in a mold where the mixture is formed into a pre-preg sheet. Subsequently, the pre-preg sheet is subjected to compression molding at elevated temperatures to produce a finished composite trim panel. As part of the final compression molding step, a decorative coverstock can be included to produce a finished trim panel having a decorative cover.
