摘要： A polyurethane system for use as a binder in producing foundry molds and cores in metal casting, especially in a “cold box” process, has a polyol component with one or more polyols having at least two OH groups per molecule, with at least one phenol resin, and an isocyanate component. Particularly, the isocyanate component includes a reaction product of at least one cyclic amine with at least one polyisocyanate having at least two NCO groups per molecule. Each cyclic amine is characterized as an amine having at least one NH— group and from four to six carbon atoms. Examples of the cyclic amine include ε-caprolactam and/or 3,5-dimethylpyrazole. Observed advantages include better humidity resistance and improved mold release properties.

摘要： Multi-layered golf ball core sub-assemblies and the resulting golf balls are provided. The core structure includes an inner core (center) comprising a foam composition, preferably foamed polyurethane. The intermediate and outer core layers are preferably formed from foamed and non-foamed thermoset compositions. For example, the intermediate core can be formed from a thermoset rubber so there are adjoining foam core layers (inner and intermediate) and the outer core layer can be formed from a non-foamed thermoset rubber. The core layers have different hardness and specific gravity levels. The core assembly preferably has a positive hardness gradient extending across the entire assembly. The core structure and resulting ball have relatively good resiliency.

摘要： An expandable polyurethane composition contains (A) a polyisocyanate, (B) an active hydrogen containing compound containing (B1) a polyol and (B2) water, and (C) a cross-linking agent composition. The cross-linking agent composition (C) contains a cross-linking agent (C1) and a carboxylic acid (C2). The cross-linking agent (C1) can be selected from an alkanolamine (a) represented by an expression: HxR1yN((R2O)nH)3-x-y, and an aminosilane (b) represented by an expression: (R3O)qR43-qSi—R5—(NHCH2CH2)pNR6R7. A content of the cross-linking agent composition (C) is 0.1 parts by mass to 20 parts by mass relative to 100 parts by mass of the active hydrogen containing compound (B), and the containing number of moles of the cross-linking agent (C1) is larger than that of the carboxylic acid (C2). It is possible to delay a reaction without deteriorating a final reactivity, to suppress viscosity increasing just after an injection into a mold, to improve hardness and to attain lowering of a pressure to be applied to a cell communication.
