This invention relates to biodurable, reticulated elastomeric matrices that are resiliently-compressible, their manufacture and uses including uses for implantable devices into or for topical treatment of patients, such as humans and other animals, for therapeutic, nutritional, or other useful purposes.

Reticulated elastomeric matrices, their manufacture and use in implantable devices

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

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

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.

A transparent adhesive coating or film based on polyurethane. A polyurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one bifunctional chain-lengthening agent containing an aromatic nucleus.

Polyurethane-based adhesive coating or film, and use of same in

A transparent adhesive coating or film based on polyurethane. The coating or film comprises a polurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one chain-lengthening agent which is a product of the reduction of dimeric acid to a diol. The adhesive coating or film is employed in laminated panes of glass and/or plastic material.

Replacement of one-third to two-thirds of the short chain diols in a polyisocyanate/polymeric polyol/short chain diol molding composition with a hydroxyalkyl-melamine provides shaped articles of increased high temperature stiffness and reduced heat sag. The hydroxyalkylmelamine is strongly catalytic for the isocyanatepolyol reaction.

Reaction injection molding compositions and process

Synthetic resins having a topologically interpenetrating polymeric network comprise macrocyclic structures of chemically different, crosslinking polymers which are permanently entangled with each other. The several macrocyclic structures that are present are characterized by the absence of chemical bonds between the individual networks.
