NanoPore™ Thermal Insulation


NanoPore™
thermal insulation is a porous solid that is prepared by one of several processes which yield both low density and small pores. Its chemical composition is silica, titania and/or carbon in a 3-D, highly branched network of primary particles (2-20 nm) which aggregate into larger (nm to mm) particles The material has pore sizes ranging from 10-100 nm. It is this nano-scale porosity that gives NanoPore™ its excellent thermal performance

Because of its unique pore structure, NanoPore™ Thermal Insulation can provide thermal performance unequalled by conventional insulation materials. In the form of a vacuum insulation panel (VIP), NanoPore™ Thermal Insulation can have thermal resistance values as high as R40/inch - 7-8x greater than conventional foam insulation materials. A comparison of the thermal performance of NanoPore™ Thermal Insulation versus conventional insulation materials is shown below.

Due to unique structure, its conductivity can actually be lower than air at the same pressure. Its superior insulation characteristics are due to the unique shape and small size of its large number of pores. Gas molecules within the matrix experience what is known as the Knudsen effect, which virtually eliminates exchange of energy in the gas, effectively eliminating convection and lowering overall thermal conductivity. Solid phase conduction is low due to the materials low density and high surface area, and NanoPore™’s proprietary blend of infra-red opacifiers greatly reduce radiant heat transfer. NanoPore™ Insulation may be used over a wide temperature range from below cryogenic (<-196 C) to high temperatures (>800 C).

NanoPore™ Thermal Insulation - Grades

Our standard thermal insulation product is NanoPore™ HP-150. This is the material uses in most of our VIPs and inserts. NanoPore™ HP-150 can be used at temperatures up to 300C, but for higher temperature use NanoPore produces a special high temperature insulation, NanoPore™ HT-170 which can be used up to 800C and above in some cases. For applications with highly specific performance requirements, custom grades of NanoPore™ Thermal Insulation can provided to meet a project's special needs. /font>

NanoPore™ thermal insulation begins as a proprietary blend of nanoporous powders which are pressed into semi-rigid boards. These are cut to size and shrink-wrapped for ease of handling. For some applications these boards are used directly, but in most cases they are processed into vacuum insulation panels, either by NanoPore or by the end user. End users may purchase these boards as VIP inserts.

To make a VIP, the inserts are encased in a metalized plastic barrier film and then sealed under vacuum. Various barrier materials may be employed to provide the desired performance depending upon the temperature, size, and desired lifetime. The completed product is a vacuum insulation panel (VIP).

A standard VIP can operate in a temperature range from below 330F (<-200C) to 250F (120C), the maximum continuous working temperature of the barrier film. For higher temperature applications, custom vacuum enclosures, made from metal or another impermeable skin, may be used to house the core material.

For applications where a VIP cannot be used (such as high temperature applications) NanoPore has experience working with customers to design, and if needed, build custom containment for the insulation.
