Major markets and market segments served by INEOS Joliet LLC chemical intermediates include:


Packaging: PIA

Purified Isophthalic Acid is an intermediate in the production of PolyEthylene Terephthalate (PET) copolymer resins for plastic bottles and food packaging. PIA provides clear bottles in a range of shapes and sizes by disrupting resin crystallinity, broadens the processing window for bottle fabrication that reduces cycle time and lowers energy requirements, improves taste in bottled water, and helps reduce permeability to carbon dioxide and oxygen to keep beverages carbonated and flavorful longer.


Industrial Coatings: PIA

Purified Isophthalic Acid is a key ingredient in polyester and alkyd coating resins used in high solids, water-reducible, and powder coating applications. PIA provides water resistance, hardness, flexibility, weatherability, and fast cure when used on diverse products like home appliances, automobiles, wood finishes, kitchen cabinets, and outdoor and metal furniture.


Electrical Components and Wire & Cable: TMA

Trimellitic Anhydride used to make vinyl plasticizers having low volatility making them ideal for PVC applications requiring long-term flexibility like electrical wire & cable insulation, automobile interiors (retention of softness and elimination of window fogging), appliance gaskets on dishwashers, refrigerators, freezers, and flat-roof membranes.


Medical: TMA

Plasticizers based on TMA are highly permanent for PVC medical products, combining very low volatility with good extraction resistance and are used in applications like haemodialysis tubing, neonatal care and blood platelet storage bags.


Automotive: MAN

Maleic Anhydride is a key component in making lubricating oil additives, dispersants and corrosion inhibitors used in gasoline and diesel engines.

Boat 2

Composites: MAN

Maleic Anhydride is an essential component in making unsaturated polyester resins used to fabricate boats and personal watercraft, showers, tubs, and bathroom sinks, kitchen countertops, and automobile body panels and facia.
