Morgan Advanced Ceramics Vacupor® NT Porextherm
Categories:	Ceramic
Material Notes:	Vacupor® NT is a microporous insulation material which has an extremely low thermal conductivity coefficient giving it very good insulating properties. Vacupor® NT consists of inorganic oxides. The main constituent is fumed silica, the other components are opacifiers for minimizing infrared radiation, and silicates. Vacupor® NT (core material) is not flammable and meets the requirements of IMO FTPC part 1 and DIN ISO 4102 part 1, A1. Vacupor® NT is heat sealed under vacuum in a multilayer vacuum metalized film. The very low internal pressure and the microporous panel core enable it to reach extremely low thermal conductivity values. Application: Vacupor® NT was specially developed for applications in vacuum insulation technology. The low density and the specially developed IR opacifiers contained in these grades greatly reduce the thermal conductivity of Vacupor® NT Systems. Typical applications: Vacupor® NT is also successfully used as insulation material in the following areas: Domestic appliances (refrigerator and freezer cabinets) Absorption refrigerators Cryogenic freezer Temperature controlled packaging Transport boxes Facade elements Terrace insulation Cold storage floor insulation .
