Specifications comply with ASTM C534-88.

* Figures show the average values obtained by the world well-known testing institutes.

** Tested according to DIN, JIS, ASTM and others.

*** Average density of insulation thickness over 20 mm.

**** At temp. under -57 °C AEROFLEX becomes hard, but it does not affect thermal conductivity nor water vapor permeability. In the heating applications AEROFLEX can stand +125 °C continuously, and the adhesive up to +100 °C.

***** Water vapor permeability tests were done under test method ASTM E96 dehydrate test method at 37.8 °C.
