FMC® Polysulfide
Time Tested FMC Polysulfide
Used by artists and industry for over 60 years,
FMC® Polysulfide rubbers are soft and very
strong…perfect for making molds of
originals with deep undercuts. They can
be applied to wet models or sulfur based
clays without inhibition. Molds last for
years in your mold library.
From polysulfide molds, gypsum segments
are assembled to make steel molds used to
make production tires.
FMC® rubber was used to mold an 8 ft. (2.4 m) clay model of a horse based on
Leonardo DaVinci drawings and chronicled in National Geographic Magazine.
