Promalight 320
Promalight 320 and 320HD are a nanoporous insulation material for the most demanding thermal insulation applications where the largest temperature drop is required through the thinnest possible cross section with lowest possible mass.
- Thermal conductivity starting at 0.023W/mK
- Best performing product in its class
- Available in a range of finishes (Plain, PE shrink wrapped, foil-faced, mica-faced)
- Machinable (HD grade for improved machining definition)
Advantages and properties
- Improved thermal performance reduces cross sectional thickness
- Lightweight thin panels
- Low thermal capacity reducing heat soak
- Easily machinable
- Chemically inert
- Thermally resistant to 950°C
