NONFLAMMABLE PAPER This nonflammable paper from Scheufelen paper company was used during Apollo flights. For Space Shuttle and ISS there was no need for a nonflammable paper, since they did not use pure oxygen atmosphere any more.
A cellulosic material, developed by the Scheufelen Paper Company of Germany and processed primarily as a paper, carbonizes in the presence of a flame but does not propagate the flame. This nonflammable characteristic is evident in both air and oxygen-enriched atmospheres. This paper lends
itself well to printing and, with some minor exceptions, has physical properties that are comparable to conventional paper.
This paper can be processed into a continuous roll of 0.5—inch—thick foam, similar to papier—mache. When placed on a ceiling, for example, the foam has both the appearance and function of conventional acoustic tile and offers the additional advantage of nonflammability.
In addition to the paper, a process called Laminite which treats -cellulose-base fiberboard with ammonium aluminum sulfate has been evolved.
The resultant material is minimally flammable in oxygen and nonflammable in air. It can be formed wet, coated, cemented, and Joined like a composite; yet it is lightweight and inexpensive.
