  1) fine and uniformity cells

  2) low thermal conductivity

  3) perfect flame resistance

  4) good low-temperature dimensional stability.

It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.
