Thermal radiation can easily penetrate the vast majority of insulation materials, even those designed for high temperatures. That’s why our engineers have developed brand new multilayer insulation packages to reduce high temperature radiation heat transfer. Our high density MLI packages include up to 18 layers per inch and are effective in environments up to 1000°C.
What is MLI?
You have probably seen images of spacecraft and satellites soaring through outer space while wrapped in silver or gold foil. This super shiny, highly reflective material is called multi layer insulation (MLI).
Multi layer insulation is composed of multiple layers of thin, reflective material, and is used to reduce radiation heat transfer. While very effective at insulating against radiation, these layers often include materials with high thermal conductivity. Due to the presence of conductive materials, MLI is most effective in high vacuum environments. It is an ideal insulator in outer space, where radiation is abundant and convection and conduction are virtually nonexistent.
What makes our MLI different?
High temperature capabilities
Traditionally, high vacuum multilayer insulation has been limited to cryogenic applications. MLI performs better in high vacuum environments, and many vacuum systems encounter problems with contamination when taken to higher temperatures. Our MLI packages are different because our MLI is contained within the vacuum annulus of Insulon® components. Insulon® vacuum spaces are able to perform in high temperature environments without contamination issues. Insulon® components have a maximum operating temperature of 1000°C.
Ultra thin profile
Without our MLI, Insulon® components can be as thin as 0.25 mm. We increase the width of the vacuum space to accommodate your desired amount of MLI. Increasing the number of layers results in increased insulation performance against radiation.
High layer density
Our high density MLI can pack up to 18 layers per inch.
What is Insulon®?
Insulon® is an advanced form of thermal insulation that uses specialized vacuum barriers to reduce convective heat transfer. Insulon® can be built into the walls of cylindrical stainless steel parts including tubes, pipes, cans, containers, and flasks. The wall of Insulon® components can be straight, bent, or flexible. Our high temperature, high density MLI can be built inside the vacuum annulus of any Insulon® part.
