Cellon

from Wikipedia, the free encyclopedia

Cellon or Zellon is a flame-retardant mixture of cellulose acetate (also known as acetyl cellulose) and camphor . It is soluble in acetone .

As a film, it can hardly be distinguished from cellophane . Arthur Eichengrün received a patent for it in 1909 and ran the Cellon works in Berlin. In 1911 RWS in Troisdorf acquired a manufacturing license. During the First World War, it was used to cover aircraft such as the Linke-Hofmann R types in order to make them "transparent". The upholstery fabric of aircraft was also coated with cellon ( tension varnish ) to smooth it . Cellon lacquer was also used as an electrical insulating material. Cellon records were also made. Cellon is an important part of security film because it is significantly less inflammable than celluloid film . In 1933, Cellon fire protection was recommended as a preventive measure against aerial bombs.

Cellon is used as an intermediate layer for splinter-resistant laminated glass, but also in the manufacture of gas and breathing masks and for closing drinking and tube caps. During the Second World War, Cellon was used as face protection in heavy snowfalls and freezing rain.
