We can offer a broad range of standard insulation packages with polyester foils and different spacers as well as crinkled insulation lay-ups.
Multi-Layer Insulation for cryogenic applications is covered by the Coolcat Line of Multi-Layer Insulation products:
Coolcat 1 – Sheets
10 Layers spot welded lay-up from SINGLE side aluminized, CRINKLED 6 μm polyester film (perforated), 3.00 m x 1.34 m
Coolcat 2 – Sheets and Roll Material
10 Layers (spot welded) lay-up from DOUBLE side aluminized, 6 μm polyester film (perforated), interleaved with 10 layers polyester knit-woven spacer, 3.00 m x 1.50 m or rolls of 1.5 m x 50 m
Coolcat 2 NW
10 Layers (spot welded) lay-up from DOUBLE side aluminized, 6 μm polyester film (perforated), interleaved with 10 layers polyester non-woven spacer, 3.00 m x 1.50 m or rolls of 1.5 m x 50 m
10 Layers lay-up from DOUBLE side aluminized, 12 μm polyester film (perforated), interleaved with 10 layers polyester non-woven spacer, 1.9 m x 50 m
Coolcat B-R50 – Cryogenic Adhesive Tape
Low emissivity tape optimized for use under cryogenic environment with low outgassing.
Coolcat 4K – Helium Can AI-PET Laminate
Coolcat 4K – Helium Can Al-PET laminate is a 12 μm PET foil with aluminium coating on both sides and a 6 μm aluminium foil laminated at one side. Coolcat 4K laminate combines the low absorptance of a 50 μm aluminium foil with the good handling properties of a polyester foil.
Coolcat 4K does not crinkle the way aluminium foils do and has the higher tear resistance of a laminate.
Coolcat 4K general properties:
- Very low absorptance at 4 K
- Pre-cut using cost efficient LASER cutting
- Easy to assemble
- Saves labour costs at customer side
- Maximum width: 1.47 m
For superconducting magnets:
- Minimum aluminium foil thickness
- Lower heat dissipation at 4 K incurred by Eddy currents
- Lower Lorentz forces at quench
Coolcat H – Welding Protection
Coolcat H – Welding Protection is a laminate of aluminium foil and fiber-glass cloth. Coolcat H protects polyester super-insulation against welding heat. Welding protection is needed because polyester super-insulation is flammable and melts at 250°C. Coolcat H insulates by reflecting the welding heat at its aluminium surface and by featuring the low conductivity of fiber-glass cloth.
Coolcat H properties:
- Temperature resistance:
- E-Glass cloth: 500°C
- Adhesive: 150°C
- Maximum width: 1.0 m
- Weight: 680 g/m²
- Thickness: 0.9 mm
- Fiber-glass diameter larger than 0.006 mm (non respirable)
- Pre-cut using cost efficient automated cutting
- Also available in rolls of 150 mm wide and 50 m long
Coolcat Cryogenic Piping
10 Layers spotwelded lay-up from DOUBLE side aluminized, 6 μm polyester film (perforated), interleaved with 10 layers polyester spacer, 3.00 m x 1.50 m, including tapes for mounting and glass fibre reinforced spacers for supporting the cryogenic pipe in its vacuum jacket according to customer specification.
