Chemical Dispersions
& Masterbatches

Seacon manufactures chemical dispersions for the rubber industry and chemical masterbatches for the plastics industry at our state-of-the-art factory in Charlotte, NC. Though in rubber we use the term “dispersions” and in plastics we use “masterbatches,” the concept is the same. We pre-disperse chemicals into a binder system to make slabs, sheets, pellets, and mini-pellets.

These forms are preferred for a variety of reasons: easier to weigh, better housekeeping, no risk of dust cloud explosions, quicker and better dispersion in rubber compounds, cleaner and more precise incorporation on a two roll open mill, consistent and dust-free side port metering during continuous extrusion, compatibility with automated pneumatic material handling systems, etc.
