    Actually, you can use both flammable and inflammable in English which makes it twice as confusing...

    It's the same here. "Flammable" is a later word invented by people who worried that inflammable would be misunderstood.

    No, I suspect 'dimensional stability' is what is being discussed here,
    not "life expectancy".

    Speaking of Flammable comments...

    When I was still a free thinker, I learned that there was an actual difference in meaning between those words.
    Curious, I visited Mr. Wikipedia to see what he could remember, since he was a free thinker once too.
    There, I found this amusing but quite offensive quote:

    " The common word meaning "combustible" is inflammable.
    Unless you are... concerned with the safety of children and illiterates, use inflammable. "


    --------------------------------------------------------------







    The full quote sounds like it could have been written by Ambrose Bierce:
    The Elements of Style (by Strunk and White) says:

    Flammable. An oddity, chiefly useful in saving lives. The common word meaning "combustible" is inflammable. But some people are thrown off by the in- and think inflammable means "not combustible." For this reason, trucks carrying gasoline or explosives are now marked FLAMMABLE. Unless you are operating such a truck and hence are concerned with the safety of children and illiterates, use inflammable.

    Just use "combustible". And that way, incombustible does mean the opposite.

    PET, up to the reports published so far, has both, greater dimensional stability as well as greater long term (archival) stability.

    So far there were cases reported of TAC based films that had lesser longevity than NC based films.

    "Inflammable means flammable? What a country!" ~Dr. Nick Riviera

    I have had some problems with light piping in 35mm b&w film on a PET base...it did not have a nice remjet backing like Kodachrome.

    Hi all,

    I just stumbled upon this link, I think you will find it interesting. Also in the light of the "How film is made" thread:

    Marco,
    That's a really excellent summary. Good stumbling! Thanks for passing it along.
