    摘要: A thermoplastic composition includes a poly(arylene ether), a hydrogenated block copolymer, a pre-blend of a thermoplastic vulcanizate and a hydrogenated block copolymer, an ethylene/alpha-olefin copolymer, and a hydrocarbon resin. Pre-blending the thermoplastic vulcanizate with a portion of the hydrogenated block copolymer was found to markedly improve the flame resistance and physical properties of the composition compared to those of compositions in which the thermoplastic vulcanizate and hydrogenated block copolymer are separately added to the final compounding process. Addition of hydrocarbon resin further improves the balance of flame retardancy and physical properties.

    摘要: Articles made from poly(arylene ether) compositions wherein injection molded test specimens having a thickness of 2.5 mm of the compositions exhibit an energy to maximum load of at least 50 kg-cm under ISO 6603 after being subjected to autoclave sterilization with steam heat at 121° C. for 83.2 hours and exhibit an average percent change in energy to maximum load of less than or equal to an absolute value of 10% after 83.2 hours under the same autoclave sterilization conditions. The test specimens are independently prepared using one of injection molding, compression molding, blow molding, sheet extrusion, or thermoformed techniques. Articles include various trays, cages, housings, medical instruments, and other articles that are subjected to steam autoclave sterilization.
