Cornerstone Chemical

What Cornerstone Chemical does

Cornerstone Chemical Company, LLC is a privately held intermediate chemicals manufacturer operating a single integrated production campus, the 800-acre Cornerstone Energy Park in Waggaman, Louisiana (with corporate offices in Metairie). The company traces its operations to a 1952 American Cyanamid groundbreaking and has produced acrylonitrile, melamine, sulfuric acid, and urea at the site continuously for over 70 years, with melamine added in 1971 and the original acetylene-based acrylonitrile process replaced by a Sohio-licensed propylene route in 1966. The site is co-located with strategic tenants including CF Industries (ammonia, acquired on-site in 2023), Röhm (methacrylic acid, on-site since 1977), and UBE C1 Chemicals America (lithium-ion battery chemicals under construction), with shared utilities, feedstock pipelines, and rail/river logistics.

Cornerstone's product technology centers on a single-site propylene-based acrylonitrile process (historically supported by proprietary filtration enabling uniquely high purity and a global number-two producer position), an integrated melamine line (~70% of global melamine demand is tied to laminates and wood adhesives), a sulfuric acid regeneration plant (divested to Ecovyst in March 2025 for $35M), and urea production backed by on-site ammonia supply. End markets span aerospace and defense (acrylonitrile for carbon fiber in F-35, F-16, CH-53K, UH-60 platforms and commercial aircraft including Airbus A350), automotive (acrylonitrile for synthetic tire rubber enabling 60,000+ mile tire life), construction (melamine for plywood, MDF, particleboard, and laminates), agriculture and emissions control (urea for fertilizer, NOx abatement, DEF), and electronics.

The business model is direct-to-customer B2B sales of intermediate chemicals on multi-year contracts, priced by unit (e.g., $/lb or $/MT) with periodic melamine price-increase notices, distributed via pipeline, truck, rail (five Class I railroads), and a Mississippi River deep-water dock. The company runs dedicated customer service teams by product line with US toll-free and European (Newcastle/Amsterdam) coverage. In February-March 2025 Cornerstone announced the mothballing of its acrylonitrile unit (effective June 30, 2025) and the sale of sulfuric acid operations, retaining melamine and urea as the core franchises while pivoting the park toward new energy-related tenants such as UBE.

Revenue model

1. Acrylonitrile Sales: Sale of acrylonitrile, a versatile organic compound used in hard plastics, acrylic and carbon fibers, synthetic rubbers, wind turbine blades, solar battery panels, pharmaceuticals, and medical treatments. Cornerstone is the second-largest global acrylonitrile producer.
2. Melamine Sales: Sale of melamine used in insulation, laminates, adhesives, flame retardants, plastics, foam cleaners, wood adhesives, and construction materials. Approximately 70% of global melamine demand comes from laminates and wood adhesives.
3. Sulfuric Acid Sales: Sale of sulfuric acid as a drying agent in industrial gas production, car batteries, gasoline refining, and methyl methacrylate (MMA) manufacturing. (Note: Sulfuric acid operations were sold to Ecovyst in March 2025)
4. Urea Sales: Sale of high-quality urea solutions for agriculture (fertilizer), stationary NOx abatement, and diesel exhaust fluids.

Product overview

Cornerstone Chemical Company is an intermediate chemical producer operating as a single-location manufacturing facility at Cornerstone Energy Park in Waggaman, Louisiana. The company produces four primary chemical products: Acrylonitrile (a reactive building block monomer for plastics and carbon fibers), Melamine (used in laminates, resins, and flame retardants), Sulfuric Acid (industrial drying agent and battery acid), and Urea (fertilizer and diesel exhaust fluid). These products serve diverse end markets including aerospace, automotive, electronics, construction, and agriculture. In 2025, the company sold its Sulfuric Acid operations to Ecovyst and announced mothballing of its Acrylonitrile unit.

Products and services

• Acrylonitrile A reactive building block monomer (C3H3N) produced via catalytic ammoxidation of propylene, used in acrylamide, acrylic fibers, nitrile rubber, elastomers, ABS plastics, surface coatings, carbon fibers for aerospace, and synthetic rubbers for automotive tires.
• Melamine An odorless white powder compound used as a major raw material in coatings, resins, laminates, flame retardants, molding compounds, wood adhesives, plywood, medium-density fiberboard, countertops, and thermal spray foam insulation.
• Sulfuric Acid Industrial sulfuric acid used as a drying agent in production of industrial gases, in car batteries, and for gasoline refining. Cornerstone had invested $36 million in a regeneration plant to convert spent acid back to high-quality product.
• Urea High-quality urea solutions for use in agriculture (fertilizer), stationary nitrogen oxide (NOx) abatement, and diesel exhaust fluids.
