Multi Layer Insulation Blanket

Multilayer insulation design considerations.

Multi layer insulation blanket.

Multi layer insulation mli is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics it is one of the main items of the spacecraft thermal design primarily intended to reduce heat loss by thermal radiation in its basic form it does not appreciably insulate against other thermal losses such as heat conduction or convection. Not to mention the high temperatures the onboard. They work by limiting the amount of radiative heat transfer through multiple layers of thin reflectors and spacer materials. Multi layer insulation materials consist of lightweight reflective films assembled in many thin layers.

Multilayer insulation blankets also known as mli insulation are ideal to protect the delicate instrumentation in these extreme conditions. Multilayer insulation mli blankets provide passive thermal control to a variety of spacecraft launch vehicles and instruments in vacuum. Our multi layer insulation employs two highly reflective aluminum surfaces to resist radiant heat transfer a feature not offered by traditional mass insulation. Web industries with increasing numbers of exploratory spacecraft and constellations of small satellites proliferating in the distant skies demand is rising for multi layer.

Multi layer insulation is used on satellites primarily for thermal control and protects the delicate on board instruments from the extreme temperatures of space. All of our superinsulation is made from double aluminized mylar 0005 thick polyethylene terephthalate film aluminized on both sides with nominal 400 angstroms coating. Multi layer insulation blankets consist of multiple layers of thin plastic film coated on one or both sides with an aluminized reflective material. These reflective surfaces are joined by a blanket type of fibrous center core.

These layers are typically made of polyimide and or. In actuality these things work really really well in vacuum. The benefit of multifoil insulation is that it is suitable for a range of applications from roof insulation floor insulation and wall insulation and due to the slim depth you can save valuable space on your installation. They do have their place in new construction but rarely.

They re what you do in space to get extremely slow but continuous thermal transmissions down 90 into a region where you can fix the balance with. Afm provides a wide range of mli to the aerospace community using a combination. Depending on its orbit a satellite can experience temperatures from below 200 f to well above 300 f sometimes at the same time. Obviously different conditions mean different answer but insulation blankets that combine insulation and either foil radiant barrier or plastic sheeeting vapor barrier are in general a bad idea as a retrofit because the foil or plastic acts to trap vapor in the insulation layer.
