Abstract: A lubricant blend for use on a wire exposed to an HFC refrigerant. The lubricant blend includes an organic phase and an aqueous phase. The organic phase includes a lubricant which has a defined solubility in the HFC refrigerant and a lubricity suitable for application to the wire. The organic phase also includes a solvent in which the lubricant is soluble and, optionally, a hydrophobic surfactant. The aqueous phase includes a surfactant which forms an emulsion between the organic phase and the aqueous phase, which has a defined solubility in a non-CFC containing refrigerant. A magnetic wire lubricant, method of making the lubricant blend, and compressor using the lubricant blend are also described.

Abstract: Broadly, the present invention comprises a solventless process wherein blends of thermoset polyphenylene oxide and triallylcyanurates can be processed into fiber reinforced laminates, and especially laminates prepared by the Wiggins Teape process. One aspect of the present inventive process comprises blending the polyphenylene powder with a liquid epoxy material, optionally with flame retardants and catalysts, preferably in a high shear mixer at elevated temperature, e.g. in the range of about 100.degree.-130.degree. C. The resultant upstaged or partially-cured blend is sufficiently solidified to be granulated into a powder for Wiggins Teape processing or, optionally, conventional press processing into a fiber reinforced laminates. Resin systems thus-prepared exhibit both improved solderability resistance and improved resistance to organic solvents when compared to thermoplastic systems.

Abstract: The present invention teaches polyetherimide blends which are comprised of at least one polyetherimide resin and at least one polyester resin derived from a cyclohexanedimethanol and a carbocylic acid. These blends can be utilized in applications requiring improved impact strengths compared to unmodified polyetherimide compositions.

Abstract: Broadly, the present invention is directed to a method for making a mold capable of transferring three-dimensional relief from a textured substrate to thermoplastic composite material. This method comprises the steps of preparing a molding core by loading a press with outer layers of textured substrate and an inner layer comprising a combination of an epoxy non-woven glass mat and a woven glass cloth prepreg. The press is actuated at low pressure while applying heat to pregel said epoxy and then the pressure is increased to form the molding core. Molds are prepared by loading a press with outer layers of said molding core and an inner layer comprising a combination of an epoxy non-woven glass mat and a woven glass cloth prepreg. Finally, the press is actuated at low pressure while applying heat to pregel said epoxy and the increasing the pressure to form said molds. As another aspect of the present invention, a three-dimensional relief is imprinted from a textured substrate to a thermoplastic composite.
