A development in the area of high temperature polymers, which offers solutions to many existing packaging and reliability challenges of electronics industry, is described. Packaging, protection and reliability of various electronic devices and components that include PCB's, MEM's, optoelectronic devices, fuel cell components and nano-electronic parts are becoming more challenging due to their long-term performance requirements. Parylene HT offers solutions to many existing packaging and reliability issues of electronics industry in part because of its excellent electrical & mechanical properties, chemical inertness and long-term thermal stability at high temperature exposure to over 350°C (short-term at 450 °C). Experimental results and trial runs demonstrate the ability of Parylene HT coating to meet the growing requirements of higher dielectric capabilities, higher temperature integrity and mechanical processing etc. of dynamic electronic industry. In addition, Parylene HT polymer coating truly conforms to the parts due to its molecular level deposition characteristics. Its suitability and biocompatibilty encourage researchers to explore Parylene HT's role in sensors and in active electronic devices for various industries, which include enhancing high temperature application/technologies.

Through characterization of dielectric and other properties at high temperatures, this work describes the development of a high temperature and UV stable nano/micro vapor phase deposited polymer coating for providing electrical insulation and protection of various electronics from chemical corrosion and other harsh environmental effects. Packaging, protection and reliability of various electronic devices and components, including PCBs, MEMS, optoelectronic devices, fuel cell components and nanoelectronic parts, are becoming more challenging due to the long-term performance requirements on devices. A recently commercialized high temperature polymer, Parylene HT®, offers solutions to many existing protective, packaging and reliability issues of electronic and medical applications, in part because of its excellent electrical and mechanical properties, chemical inertness and long-term thermal stability (high temperature exposure to over 350°C, short-term at 450 °C). Experimental results and commercial applications demonstrate the ability of Parylene HT coating to meet the growing requirements for higher dielectric capabilities, higher temperature integrity and mechanical processing, etc. of dynamic electronics applications. In addition, Parylene HT polymer coating truly conforms to parts due to its molecular level deposition characteristics. Its suitability and biocompatibility encourage researchers to explore Parylene HT's role in sensors and in active electronic devices for various industries.

This paper reviews the metallurgy and behavior of centrifugally cast heat-resistant alloys for ammonia, methanol, and hydrogen reformer furnaces. The alloys include HK and HP, as well as proprietary versions of these materials produced by various foundries. Alloying and metallurgical factors that affect resistance to oxidation, carburization, and high temperature creep are discussed. Examples of the effects of environment and temperature on material behavior are provided. Finally, the use of material properties to predict the long-term performance of reformer furnace components is reviewed.

This paper addresses a major challenge facing deepwater production of oil and gas: how to assure continuous flow of product under the pressures and temperatures found on the ocean floor. Syntactic foam promises to overcome the limitations exhibited by conventional insulation materials in the past. New hybrid glass and polymer chemistries with improved “hot, wet” performance survive in conditions that were formerly thought impossible. This paper presents the latest laboratory test data on these new materials, and proposes models for predicting long-term performance.
