Polyvinyl chloride volumes from Mexichem Resinas Colombia are likely to remain limited and a force majeure could remain in place until mid-October when operations should return to normal. Mexichem could not immediately be reached for comment. The Cartagena plant in Colombia can produce 400 kta of PVC. Mexichem declared force majeure September 1 shortly after Hurricane Harvey hit the US Gulf Coast, affecting plants that supply feedstock to the Cartagena plant.
