usage: inflammable and
flammable both mean “combustible.”
inflammable is the older by about 200 years.
flammable now has certain technical uses, particularly as a warning on vehicles carrying combustible materials, because of a belief that some might interpret the intensive prefix
in- of
inflammable as a negative prefix and thus think the word means “noncombustible.”
inflammable is the word more usu. used in nontechnical and figurative contexts:
inflammable clothing; an inflammable temper. Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Random House, Inc. All rights reserved.

Inflammable is not the opposite of flammable. The opposite is non-flammable.
