Abstract: A uniform cross-section and ribbed thermoplastic compressor valve which can be used as a discharge valve for a compressor and has internal rib structure and uniform wall thickness. The valve member can be made of high-performance polymeric resin such as polyimide. The valve member comprises a base member, an annular wall member, a central member protruding from the base member, and a plurality of internal wall members. The internal wall members provide the internal rib structure which strengthens the valve member and allows for light-weight construction. Preferably, there are six internal wall members and the central member has a cavity.

Abstract: Polyimide compositions can be substantially improved by incorporating in the composition an inorganic, low hardness, thermally stable, sheet silicate, such as muscovite mica, talc, and kaolinite, which results in improved wear resistance and reduced coefficient of friction.

Abstract: New polyimide polymeric blends which are environmentally friendly during compounding and give improved coefficient of friction in shaped articles prepared therefrom are provided by blending polyimides which are at least 90% imidized and substantially solvent free and have a mean particle size of about 30 .mu.m or less with at least one melt processible thermoplastic liquid crystalline polymer or polyamide and a lubricant.
