Unifrax Introduces New Microporous Insulation
Unifrax Corporation (Niagra Falls, NY, USA) has introduced Excelfrax
Microporous Insulation. The Excelfrax family of products is based on the
microporous insulation principle and is said to exhibit extremely efficient
insulating characteristics in the North American market.The Excelfrax product is composed of inorganic oxides, primarily fumed
silica. Silicates and opacifiers are added to improve the material
performance. Microporous insulation products are said to actually have
thermal conductivity values lower than still air. This, explains Unifrax,
is due to the ability of microporous insulation to block the three modes of
heat transfer (conduction, convection and radiation). The company says that
the Excelfrax range offers a number of advantages, including extremely low
thermal conductivity, thermal stability, consistent operating temperatures
and easy fabrication. The extremely low thermal conductivity allows users
to save space, reduce weight and increase operational efficiency.The products are available in several forms to solve a range of thermal
insulation problems, including Excelfrax 800 Flexliner for back-up
insulation in molten metal ladles and Excelfrax 200 VIP (Vacuum Insulation
Panel) for lower temperature insulation in appliances, packaging and other
cold storage applications.Unifrax employs more than 1,000 people world-wide in manufacturing
facilities in eight countries as well as at various regional sales offices
throughout the USA and Canada, France, UK, Germany, Belgium, Spain, Italy,
China, India, Brazil, Venezuela, Argentina and Australia. Excelfrax is
manufactured exclusively for Unifrax by Wacker Chemie GmbH and is a
registered trademark of Unifrax Corporation.
