Abstract: The present invention is drawn to a composition and thermoformable sheets and articles made therefrom. In the present invention, ranges of chain-transfer agents, thixotropic agents, and mineral filler content are balanced to minimize migration or maldistribution of coloring matter and mineral filler during curing of methyl methacrylate in a syrup and also during subsequent heating and deformation in thermoforming, to achieve constancy of impact resistance and improve stability of patterns even in deformed portions of formed sheets.
Abstract: The present invention relates to mold inserts suitable for use with thermoformable sheets made of poly(methyl) methacrylate and other thermoplastic sheet material. The inserts become an integrated part of the thermoformed product, and are characterized by having at least one removable portion or plug. The plug(s) are removed during the thermoforming process, and allow the thermoformed sheet material to shrink without creating undesirable levels of stress in the sheet material. This prevents cracking or other failure of the sheet material.
Abstract: The present invention includes new compositions for making polyurethane and polyurethane foam compositions. These compositions comprise the reaction product of an isocyanate A-Side and a B-Side comprising: (i) a polyol having a molecular weight of about 1000 g/mol or more, and having an average functionality of 2.0 or greater; (ii) a polyol having a Tg of about −80° C. or less, and having a molecular weight of about 1000 g/mol or more, and having an average functionality of 2.0 or greater; and(iii) a polyhydric alcohol having a molecular weight of about 90 g/mol or more, and having an average functionality of 3.0 or more. In the case of polyurethane foam compositions, the system also comprises water. The invention also includes processes for making the polyurethane and polyurethane foam compositions, as well as methods of adhering the same to cosmetic layers comprising thermoplastic, acrylic, and gel coat materials. The invention also includes articles made from these reinforced cosmetic layers.

Abstract: A method of making acrylic products having a relatively even distribution of visible accent particles dispersed therein. The acrylic products are made from a composition comprising an acrylic matrix comprising a monomer rich syrup and having pre-formed particles added thereto. The pre-formed particles are evenly dispersed in the matrix by virtue of their geometry, similarity in composition or specific gravity to that of the matrix. When added with the accent particles, the pre-formed particles serve the function of restricting the movement of, and thereby suspending the accent particles in an even dispersion within the matrix. The results is an even distribution of the accent particles in the finished product.
