Thermal conductivity common use in the construction and textile industries. The construction industry makes use of units such as the R-value (resistance) and the U-value (transmittance). Although related to the thermal conductivity of a material used in an insulation product, R- and U-values are dependent on the thickness of the product. Likewise the textile industry has several units including the tog and the clo which express thermal resistance of a material in a way analogous to the R-values used in the construction industry. There are a number of ways to measure thermal conductivity. Each of these is suitable for a limited range
Advanced materials industry in China Advanced materials industry in China As an important part of the national sustainable development strategy, the development of advanced materials is advancing the competitive nature and state of the art for Chinese industry. The State has put advanced materials high on its development agenda for the next decade and listed it among the key high-tech industry sectors that would be given priority for development by the State Council. At present, the pace of building China's advanced materials industry is accelerating. Advanced materials have been key fields in China's national R&D system (National High Technology Research and Development Program (863 Program)
