Super-insulation was introduced in the late 1950’s as a means of reducing radiant heat transfer in Dewar type vacuum vessels. The basic principle involves inserting multiple layers of aluminium or metallised films between the inner and outer walls of the vessel. Since these highly reflective materials are also thermally conductive, they are normally interleaved with cryogenic tissue. TFP manufactures a range of cryogenic tissues for use in super insulation. Products in the Supacool range include binder free microfine glass tissues available in a range of basis weights and chopped strand glass products with low binder contents. |

Cryogenic Insulation Tissues |
Supacool M | Supacool T | ||
| TFP’s Supacool range of lightweight tissues is designed for use in the super-insulation of cryogenic vessels. Each type of tissue in the range is available in precision-cut coils from 50mm to 1280mm wide. Tissues manufactured from 100% inorganic fibres can be used in critical applications. Easily processed, high strength tissues are also available. | Supacool M is a binder free microfine glass product with no organic constituents. It is non-flammable. The product is available at a basis weight of 15gm-2 . During manufacture, Supacool M is dried at 300°C to ensure minimum moisture content in the finished product. The product also has excellent thermal stability (melting point 600°C) so that elevated temperatures can be used to facilitate evacuation. | Supacool T is a 10g/m2 nonwoven tissue based on chopped strand textile glass fibres. This gives the product an exceptionally high void content which facilitates evacuation. Supacool T contains 5% binder which gives the product a high tensile strength. This minimises lost time while wrapping vessels. The product is manufactured with low moisture content. Elevated temperatures can be used to assist evacuation provided the binder melting point (190°C) is not exceeded. | ||
