Detail

In the 1960s, DuPont constructed the Pontchartrain Works facility in LaPlace, LA, to manufacture adiponitrile, used in the manufacturing of nylon.  Over time, the facility began manufacturing both neoprene and Kevlar® at the site.  The neoprene unit eventually became one of the largest manufacturing sites of neoprene in North America and, in 2015, was purchased by Denka and Mitsui.  The neoprene unit is now owned by Denka Performance Elastomer (DPE) and is referred to as the DPE Pontchartrain Facility.  

As landowners of the entire Pontchartrain Works property, including the property on which DPE is located, DuPont continues to manufacture Kevlar® in its separate Kevlar® unit via its subsidiary DuPont Protection Technologies. Overall, the Pontchartrain facility employs an average of 300-500 workers.
