Restriction
We have taken care to collect and present technical and performance
data which are based on supplier data, own measurements and tests.
These data are meant to help our customers in their design process
and support the selection of the best insulation type for the application. However, these data are indicative only and have to be proven
by specific measurements in the relevant environment.
Build to print: We can produce superinsulation to customer drawings. We accept the definition of blanket shapes in DXF, IGES or STEP
format.

Cryogenic Insulation (Coolcat Line)
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…
Laser Cutting:
Polyester superinsulation blankets are cut to shape using our numerically 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 cutting edges. The edges are held together by bridges of molten polyester.
However, laser cut edges are open for edge pumping (see picture).
No significant difference in thermal performance was found in comparative 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 blanket with very good handling properties. The thermal performance is
optimized by minimizing thermal shortcuts through assembly elements.
When compared to cold cut blankets, where cracks could start from
the edge of each single reflector foil, laser cut/welded blankets combine 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 perforation holes of the reflector foils (broadside pumping). Most of our
Coolcat superinsulation is made of perforated foils to allow broadside pumping. Thus the insulation gap can be evacuated more quickly and the residual vacuum pressures are lower than for edge pumping only.
We supply standard sheets and rolls of polyester superinsulation such
as Coolcat 1, Coolcat 2 and Coolcat 2 NW. These standard superinsulation 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.

Coolcat BR-50 tape is recommended for closing superinsulation blanket 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 Coolcat 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 assemble 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 aluminized 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 gravitational 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
Coolcat 1 is a crinkled superinsulation composed of 10 layers of polyester foil, single-side aluminized and crinkled.
Coolcat 1 offers a high thermal performance, especially between liquid nitrogen and liquid helium temperature levels. The crinkled polyester foil which is used in Coolcat 1 has been used in high performance cryogenic insulation for more than 50 years.
The crinkling ensures only minimum contact areas between the reflector foils, which minimizes heat conduction. Crinkled superinsulation must be applied with extra care to avoid compression and thermal shortcuts between the foils, especially at corners.
For the supercrinkled version of Coolcat 1 the reflector foil is processed 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 insulation in a loose way.
All polyester reflector foils are aluminized to provide a specific surface 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 liquid helium temperature level.
Coolcat 1 is not perforated.
Maximum baking temperature: 423 K.

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 compression).
Knit-woven spacers are more light-weight and slightly thinner than
the non-woven spacers, which are used in Coolcat 2 NW. Knit-woven 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 layers. For a good thermal performance compression of the superinsulation should be avoided. It is recommended to allow a minimum insulation 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 surface 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.
Maximum baking temperature: 423 K.

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 compression).
Non-woven spacers are dimensionally stable and therefore Coolcat 2
NW offers easier handling and more efficient installation than Coolcat 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 superinsulation should be avoided. It is recommended to allow a minimum
insulation 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 surface 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 polyester foils are perforated at an open area of 0.05 to 0.1 per cent.
Maximum baking temperature: 423 K.

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 automotive 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.
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 superinsulation should be avoided. It is recommended to allow a minimum
insulation gap thickness of 7 mm per 10 layers and to install the insulation in a loose way.
Maximum baking temperature: 523 K.
Glass fibre diameter: 16 µm (non respirable).

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 aluminium foil thickness offers lower heat dissipation at 4 K (incurred by
Eddy currents) and lower Lorentz forces at quench.

Coolcat H
Coolcat H is a welding protection made of aluminium foil and fiberglass 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 Celsius (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 degree 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 respirable.
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 efficient automated NC cutting machine.

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:

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

Space Insulation
RUAG Space offers the full range of thermal insulation materials used
for single layer insulation, multi-layer insulation and radiator surfaces
made up from polymeric or metal foils. We source raw materials for
insulation from the leading suppliers from all over the world.
RUAG Space is very active in research and development to improve
the performance and the characteristics of thermal control materials
and components. At the moment we are developing novel thermal
control films thinner and lighter than ever offered for satellites. The
mass savings target is at 30% of the insulation.
Ultrathin and Ultralight insulation
For this new multi-layer insulation also the production and integration processes have been adapted to cope with such ultrathin and
ultralight materials.
We also have business contact to the suppliers of Optical Surface
Reflectors and all thermal components needed for satellite or cryostat thermal control (e.g. heaters, thermostats, thermistors, doublers, interfillers ...).
We can offer all common outer layers of thermal insulation blankets:
