Disclosed are methods for making foam laminates having a concave surface. The methods include: (a) placing the foam sheet-containing sandwich structure in a mold; and (b) shaping the laminate in the mold to form the foam laminate having a concave surface. In the methods, the foam sheet is a slice from a foam bun in which a foaming reaction occurs such that the foam rises in a direction away from a base, such that one major surface of the sheet is a foam rise direction facing surface and the opposed major surface of the sheet is a base facing surface, and prior to placing the foam laminate in the mold, the foam sheet is oriented so that the shaping forms the foam laminate having the concave surface wherein the foam rise direction facing surface of the foam sheet faces the concave surface of the foam laminate. Also disclosed are automotive headliners and hoodliners made thereby.

Disclosed are methods and systems for preparing open-celled polyurethane foams by a discontinuous box foam process in which (a) a polyurethane foam-forming composition is deposited into a container having a gas-permeable base and (b) the polyurethane-foam forming composition is allowed to form an open-celled polyurethane foam in the container. In these methods and systems, the gas-permeable base is heated before, during, and/or after step (a) and heating is continued during at least a portion of step (b).

The present invention is directed to a process for the manufacture of three-dimensional acoustically sound automotive insulation parts. In particular, the process includes mixing a two component polyurethane resin, applying the resin to a substrate, molding the substrate and then trimming and demolding the resin applied substrate.

Process to manufacture three dimensionally shaped substrate for sound abatement

A process for incorporating sulfonic acid groups in the structure of an aliphatic, non-polar, water insoluble compound is disclosed. In the process the compound is first dissolved in an appropriate solvent and is then reacted in the presence of a catalyst and oxygen with an aqueous sulfite solution. The sulfonation renders the compound polar and water absorbent and, therefore, suitable in a variety of applications.

Sulfonated aliphatic compounds

This invention relates to a reaction injection molding process for preparing a molded product comprising reacting, at an isocyanate index of about 70 to about 130,

Injection molded parts having improved surface gloss

A thermoplastic molding composition is disclosed comprising (i) a thermoplastic polyurethane resin and (ii) an ionomer. The ionomer is a salt of a copolymer, having a weight average molecular weight of 1,000 to 200,000, of 70 to 99 percent olefin and about 1 to 30 percent of alpha, beta-ethylenically unsaturated carboxylic acid. At least some of said carboxylic acid is neutralized by a monovalent counter-ion. The composition is characterized by its improved processability.

Polyolefin ionomer as processing aid for thermoplastic polyurethane

A thermoplastic, resinous mixture, useful in the preparation of compatible blends of polyurethane with polyolefins, is disclosed. The mixture contains

Process for the preparation of filled urethane-based reinforced moldings

A soft, flexible foam characterized in having (i) a hardness, IFD 25% value, of at most 29 lbs/50 in.sup.2, as determined in accordance with Test B.sub.1 of ASTM D 3574 and (ii) a density of about 0.9 to 3.0. pounds per cubic foot is disclosed. Accordingly, the foam is prepared by reacting an organic polyisocyanate with a polyol in the presence of a catalyst and water and a compound conforming to ##STR1## where A is selected from among H, COOH, NH.sub.2, and OH, M is a counter ion, and
