| SPECIAL RECOMMENDATIONS |
|---|
| 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. |
