Laser Cutting:Polyester superinsulation blankets are cut to shape using our numeri-cally controlled (NC) cutting machines. Polyester superinsulation is laser cut whereas aluminium/glass insulation is cold cut. The laser cutting process assembles the multi-layered package around its cut-ting edges. The edges are held together by bridges of molten polyes-ter.

However, laser cut edges are open for edge pumping (see picture).No significant difference in thermal performance was found in com-parative calorimeter testing between multi-layer insulation with cold cut and laser cut edges: Laser cutting does not increase edge effects!

We can NC laser cut to a maximum width of 2.7 m. The length of the cutting area is 3.0 m, which does not limit the length of individual superinsulation blankets, as the superinsulation is fed into the cutting machine on a conveyor, forwarding the band when needed.

This method of producing polyester superinsulation has proven to be very efficient, because no additional assembly of the layers (pins, staples, welding points or similar) are required to attain a robust blan-ket with very good handling properties. The thermal performance is optimized by minimizing thermal shortcuts through assembly ele-ments.

When compared to cold cut blankets, where cracks could start from the edge of each single reflector foil, laser cut/welded blankets com-bine the strength of several thin layers and thus offer a much higher tear strength. No crack stopper holes are needed at the end of laser cuts or inside corners (<180°).

During the evacuation of the vacuum space, the air and outgassing products enclosed within the multi-layer package of the insulation can be pumped at the open edges (edge pumping) and through per-foration holes of the reflector foils (broadside pumping). Most of our Coolcat superinsulation is made of perforated foils to allow broad-side pumping. Thus the insulation gap can be evacuated more quick-ly and the residual vacuum pressures are lower than for edge pump-ing only.

We supply standard sheets and rolls of polyester superinsulation such as Coolcat 1, Coolcat 2 and Coolcat 2 NW. These standard superinsu-lation products are held together by a grid of ultrasonic spot welding points. The standard pitch of these welds is 0.3 x 0.3 m. These welds assemble the multi-layer package and ensure that the multi-layered package will not fall apart when our customers cut their own shapes using scissors, scalpels or similar.

Cryogenic Insulation (Coolcat Line)

Microscope picture of a laser cut multi-layer superinsulation blanket edge

Our product family Coolcat comprises standard insulation and tailor made insulation. Our insulation is composed of aluminized polyester foils interleaved with polyester spacer materials or is made of aluminium foils interleaved with glass spacer materials. In addition, we supply welding protection materials, tapes, sensors…


Coolcat BR-50 tape is recommended for closing superinsulation blan-ket joints. Depending on the configuration of the cryostat it may be possible to completely enclose the cold parts to be insulated with a shell of insulation blankets. In this case the taping of superinsulation joints may be sufficient to hold the insulation in place. In other cases it may be necessary to use additional fixation elements such as plastic pins.

Superinsulation types such as Coolcat 2 NF, Coolcat 2 LOX and Cool-cat H, which are not made of polyester but contain other materials such as aluminium foil or glass-fibre fleece are cold cut on our NC cutting machines using oscillating knives. This process does not as-semble the multi-layer package and so we use tag pins to hold the blanket together. We offer NC cold cutting up to a blanket size of 3.0 x 0.95 m. We cold cut larger blankets by hand if required.

The superior performance of Coolcat insulation is based on: – High quality polyester film, 6 or 12 µm thick, double side alumin-ized at minimum 40 nm (400 Angstrom).

– Reflector foils are separated with pure polyester spacer material. – 10 layers of foil and 10 layers of spacer are combined as a semi finished insulation lay-up, ready for cutting.

– The insulation is perforated for perfect evacuation of the vacuum chamber.

– RUAG Space thermal insulation is designed based on CAD models and is cut accurately on the numerically controlled laser cutting machine.

– The insulation is easy to handle due to the laser cut edges. – The insulation performance is long term stable, no degradation of insulation due to the spacer material, no flattening, limited gravi-tational compression, no severe compression effect over edges.

– The reproducability of performance in a serial production is very high, only very small deviation is measured.



Coolcat 1 is a crinkled superinsulation composed of 10 layers of poly-ester foil, single-side aluminized and crinkled.

Coolcat 1 offers a high thermal performance, especially between liq-uid nitrogen and liquid helium temperature levels. The crinkled poly-ester foil which is used in Coolcat 1 has been used in high perfor-mance cryogenic insulation for more than 50 years.

The crinkling ensures only minimum contact areas between the re-flector foils, which minimizes heat conduction. Crinkled superinsula-tion must be applied with extra care to avoid compression and ther-mal shortcuts between the foils, especially at corners.

For the supercrinkled version of Coolcat 1 the reflector foil is pro-cessed to provide a more intense crinkling.

Standard sheets are assembled by ultrasonic spotwelding points at a grid of 200 x 200 mm.

For a good thermal performance compression of the superinsulation must be absolutely avoided. It is recommended to allow a minimum insulation gap thickness of 3 mm per 10 layers and to install the insu-lation in a loose way.

All polyester reflector foils are aluminized to provide a specific sur-face resistance of 1.5 – 3.0 ohms per square (coating thickness > 25 nm). The low coating thickness minimizes edge effects caused by heat conduction within the coating, which is most important at liq-uid helium temperature level.

Coolcat 1 is not perforated.

Maximum baking temperature: 423 K.

Caution Notes: Polyester superinsulation is flammable and suitable welding protection is required (we recommend the use of Coolcat H). Coolcat 2 LOX is the only type of superinsulation in this catalogue which is liquid oxygen compatible. All other insulation types fail in test 4.4.2 of EN 1797 (Flash in drop test under liquid oxygen). For all applications a separate risk assessment is required to confirm the use of polyester superinsulation


Coolcat 2

Coolcat 2 is a spacered superinsulation composed of 10 layers of polyester foil, double-side aluminized, perforated and interleaved with 10 layers of knit-woven polyester spacer material.

Coolcat 2 offers a high thermal performance. For many years Coolcat 2 has been widely used by the research community for the insulation of cryogenic equipment at a laboratory scale.

Spacered superinsulation offers more robust thermal performance than crinkled superinsulation (for example at corners and under com-pression).

Knit-woven spacers are more light-weight and slightly thinner than the non-woven spacers, which are used in Coolcat 2 NW. Knit-wo-ven spacers are dimensionally less stable than non-woven spacers. In comparison with Coolcat 2 NW, handling and installation of Coolcat 2 insulation is more difficult.

Coolcat 2 has a nominal compressed thickness of 1.0 mm per 10 lay-ers. For a good thermal performance compression of the superinsu-lation should be avoided. It is recommended to allow a minimum in-sulation gap thickness of 3 mm per 10 layers and to install the insulation in a loose way.

All polyester reflector foils are aluminized to provide a specific sur-face resistance of < 0.8 ohms per square (coating thickness > 40 nm).

For low outgassing Coolcat 2 contains 100% polyester spacer, which has been washed and thermo-fixed at high temperature to minimize outgassing. For short pumping times all double aluminized polyester foils are perforated at an open area of 0.05 to 0.1 per cent.

*) Heat flux values measured under laboratory conditions at good vacuum (< 1 E-3 Pa); For the sizing of superinsulation for real applications it is recommended to multiply these heat flux values with a factor of 1.3 – 1.5. This is assuming good design, installation and vacuum conditions.



Coolcat 2 NW

Coolcat 2 NW is a spacered superinsulation composed of 10 layers of polyester foil, double-side aluminized, perforated and interleaved with 10 layers of non-woven polyester spacer material.

Due to its high thermal performance and good handling properties it is used in serial production of MRI and NMR cryostats at an industrial scale.

Spacered superinsulation offers more robust thermal performance than crinkled superinsulation (for example at corners and under com-pression).

Non-woven spacers are dimensionally stable and therefore Coolcat 2 NW offers easier handling and more efficient installation than Cool-cat 2 (knit-woven spacer).

Coolcat 2 NW has a nominal compressed thickness of 1.4 mm per 10 layers. For a good thermal performance compression of the superin-sulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 3 mm per 10 layers and to install the insu-lation in a loose way.

All polyester reflector foils are aluminized to provide a specific sur-face resistance of < 0.8 ohms per square (coating thickness > 40 nm).

For low outgassing Coolcat 2 NW contains 100 % polyester spacer without binder. For short pumping times all double aluminized poly-ester foils are perforated at an open area of 0.05 to 0.1 per cent.

Coolcat 2 NF

Coolcat 2 NF is a spacered superinsulation composed of 11 layers of glass fibre fleece spacer interleaved with 10 layers of pure aluminium foil.

Coolcat 2 NF is high temperature tolerant and non flammable. It has been tested to be self-extinguishing in 100 per cent gaseous oxygen environment. It has been used for the thermal insulation of automo-tive cryogenic hydrogen storage tanks. The glass fibre spacer has a binder content of 8 per cent and therefore the insulation is not liquid oxygen compatible in accordance with ASTM D2512-95.

Glass fibre diameter: 16 µm (non respirable).

Coolcat 2 NF sheets are held together by nylon tag pins along their short ends at a pitch of 0.2 m.

Coolcat 2 NF has a nominal compressed thickness of 5.0 mm per 10 layers. For a good thermal performance compression of the superin-sulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 7 mm per 10 layers and to install the insu-lation in a loose way.




300 to 77 20 foils + 20 spacers > 1.25

*) Heat flux values measured under laboratory conditions at good vacuum (< 1 E-3 Pa); For the sizing of superinsulation for real applications it is recommended to multiply these heat flux values with a factor of 1.5 - 2. This is assuming good design, installation and vacuum conditions. The thermal conductance of aluminium foils is much higher than the one of aluminized polyester foils and therefore thermal edge effects are more severe.

Coolcat 2 NF is available in standard sheets:



PL100298 3 x 1 9 0.540



Coolcat 2 LOX

Coolcat 2 LOX is a spacered superinsulation composed of 5 layers of pure aluminium foil interleaved with 5 layers of glass fibre cloth spac-er.

Coolcat 2 LOX is high temperature tolerant and liquid oxygen com-patible: Coolcat 2 LOX insulation is oxygen compatible in accordance with ASTM D2512-95. The glass fibre spacer has been desized and heat cleaned. The insulation is free of organic constituents.

Glass fibre diameter: 5 µm (non respirable).

Coolcat 2 LOX sheets are provisionally held together by nylon tag pins along one short end at a pitch of 0.2 m.

Coolcat 2 LOX has a nominal compressed thickness of only 0.4 mm per 10 layers. For a good thermal performance compression of the superinsulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 1 mm per 10 layers and to in-stall the insulation in a loose way.




300 to 77 10 foils + 10 spacers > 4.41


*) Heat flux values measured under laboratory conditions at good vacuum (< 1 E-3 Pa);For the sizing of superinsulation for real applications it is recommended to multiply these heat flux values with a factor of 1.2 - 1.5. This is assuming good design, installation and vacuum conditions. The thermal conductance of aluminium foils is much higher than the one of aluminized polyester foils and therefore thermal edge effects are more severe.

Coolcat 2 LOX is available in standard sheets:



PL100252 3 x 1 9 0.247



Coolcat 2 NI

Coolcat 2 NI is a spacered superinsulation composed of 10 layers of polyester foil, single-side aluminized in squares of 10 mm x 10 mm / double-side aluminized in squares of 20 mm x 20 mm, interleaved with 10 layers of non-woven polyester spacer material.

Coolcat 2 NI minimizes eddy currents and still offers a high thermal performance. It has been developed for applications where the insulation is exposed to varying magnetic fields: – SQUID sensors: Reduction of magnetic thermal noise – Superconducting machines (Fault current limiters, motors, genera-tors,…): Reduction of heat dissipated in the superinsulation coat-ings.

Coolcat 2 NI has a nominal compressed thickness of 1.4 mm per 10 layers. For a good thermal performance compression of the superin-sulation should be avoided. It is recommended to allow a minimum insulation gap thickness of 3 mm per 10 layers and to install the insu-lation in a loose way.

For low outgassing Coolcat 2 NI contains 100 % polyester spacer without binder. Coolcat 2 NI is not perforated.

Coolcat 4K

Coolcat 4K is a low absorptance helium can laminate.

It is a laminate of a 6 µm pure aluminium foil and a 12 µm polyester foil, double-side aluminized.

Coolcat 4K laminate combines the very low absorptance of a pure aluminium foil with the good handling properties of a polyester foil.

As a superconducting magnet thermal insulation the small alumini-um foil thickness offers lower heat dissipation at 4 K (incurred by Eddy currents) and lower Lorentz forces at quench.

Coolcat 4K does not crinkle and tear the way aluminium foils do. It has the higher tear resistance of a laminate. This makes the installa-tion of the insulation easier and saves labour cost.

Coolcat 4K is available at a maximum width of 1.830 m. We offer customized Coolcat 4K sheets to a maximum width of 1.750 m. These sheets are cut to customer specification using our cost effi-cient automated NC laser-cutting machine.

Installation: The mat side of the foil is the aluminium foil side and shall be used for thermal insulation. The shiny side is the aluminized polyester side and shall face the cold surface. An adhesive transfer film can be applied to the aluminium coating of the shiny side of the laminate for its attachment to the cold helium vessel surface.

Coolcat H

Coolcat H is a welding protection made of aluminium foil and fiber-glass cloth.

It is recommended for the protection of polyester superinsulation against welding heat. This welding protection is needed because polyester superinsulation is flammable and melts at 250 degree Cel-sius (523 K).

Coolcat H insulates by reflecting the welding heat at its aluminium surface and by featuring the low conductivity of fiber-glass cloth in air under ambient pressure.

The maximum service temperature of the E-Glass cloth is at 500 de-gree Celsius (773 K). The adhesive of the laminate fails above 150 degree Celsius (423 K). Welding trials are recommended to confirm if one layer of Coolcat H is sufficient for the customer application.

The glass fibres have a diameter of larger than 6 µm and are not re-spirable.

Coolcat H is available in rolls of 150 mm wide and 50 m long.

We offer customized Coolcat H sheets to a maximum width of 1 m. These sheets are cut to customer specification using our cost effi-cient automated NC cutting machine.

Coolcat B-R50

Coolcat B-R50 is a low emissivity adhesive tape optimized for use under cryogenic environment. It is composed of a 25 µm polyester foil carrier, double-side aluminized and a high purity pressure sensi-tive acrylic adhesive.

Coolcat B-R50 cryogenic adhesive tape has been developed specifi-cally for thermal insulation in cryogenic applications, to provide low-est infrared emittance on its outer surface. This tape has been devel-oped to replace tapes, which have a shiny appearance, but are second surface mirrors only.

It is most recommended for the closing of superinsulation joints.

Bonding strength at room temperature: – Peel strength: min. 16 N / 25 mm width (AFERA 5001) – Shear strength: min. 60 N / 625 mm² (AFERA 5012)

The specified bonding strength is achieved within 10 minutes after application and will increase by 30 per cent after 24 hours; zero peel strength at 230 K.

The tape meets the standard outgassing requirements for satellites of the European Space Agency.

The adhesive of the tape is protected by a release liner. We offer tape dispensers, which automatically wind up the release liner.

The tape is available 25 mm (1 inch) or 50 mm (2 inches) wide. It is delivered on cardboard core. The minimum order quantity is one roll, but it is more economic to order complete packing units:
