International is specialized in the sulfur based derivatives
chemistry historically used as fungicide in the agricultural field
and since the beginning of the 20th century, for applications in
the rubber vulcanization.
Our Lesgor plant uses particularly
carbon disulfide which reaction
with various amines leads to carbazides (used in the agricultural
field), to thiurams or thiocarbamates (rubber) and thioureas (rubber
and metal surface treatment).
Our Rion plant includes
different kind of chemistries depending on the raw material used:
- chlorine and cyanide sodium combined with amines
generate guanidines (vulcanization accelerators) ;
- sulfur monochloride reaction with morpholine gives
a powerful sulfur donor involved in the vulcanization process
- phenol is used to produce an additive for rubber
to bonding agents used in the antivibratory parts (automobile), to mention but a few applications.
These products are marketed under the trademark EKALAND™.
Usually manufactured in fine powder
form, MLPC International has developed a new polymer-bound form
of the EKALAND™ products in order to improve their handling
and dispersion in the rubber blends. These dust free polymer-bound
masterbatches, in pellet or slab form, are marketed under the name
of MIXLAND+ ® range.
