SPECIAL RECOMMENDATIONS

          Water desorption corresponds to a geometrical shrinkage & a change in hemispherical emittance.

          Available thickness range from 7.6 to 127 mm; max. width: 1320 mm. Thinner film may be available soon.

          Flammability depends on film thickness.

          Etched by oxygen atoms in low earth orbit at a rate of approx. 3 x 10-24 cm3/atom.
