Producer
Lubrizol Corporation
Lubrizol Corporation (Wickliffe, Ohio; wholly owned Berkshire Hathaway subsidiary since 2011 acquisition for $9.7B by Warren Buffett) is the world's dominant CPVC compound producer and technology licensor, holding a near-monopoly in the US CPVC pipe compound market (~75-80% US share) through its FlowGuard Gold (residential/commercial hot water plumbing) and BlazeMaster (residential and light commercial fire sprinkler systems) branded compound products. Lubrizol owns the critical post-chlorination technology patents and trade secrets for producing CPVC from PVC resin — any CPVC pipe manufacturer globally either sources Lubrizol compound or operates under a Lubrizol technology license. Lubrizol's CPVC lock-in mechanism is similar to its Carbopol brand (polyacrylic acid polymer used in hand sanitizer and personal care gels): Berkshire Hathaway's Lubrizol subsidiary holds dominant market positions in both residential fire sprinkler pipe polymer AND the gelation agent for hand sanitizers. Lubrizol also makes lubricant additives, fuel additives, and specialty industrial chemicals — a specialty chemicals conglomerate that also controls residential fire safety infrastructure materials.

USOhio · manufacturing
Lubrizol Corporation primary headquarters and specialty chemicals research campus in Wickliffe, Lake County, Ohio. This campus is the nerve center for Lubrizol's CPVC technology program including FlowGuard Gold and BlazeMaster compound development, quality control, and technical licensing. Lubrizol's Wickliffe campus is where CPVC chlorination chemistry, compound formulation, and pipe system certification testing are conducted. CPVC compound is manufactured at multiple Lubrizol sites and compounded by Avient (Avon Lake). Source: https://www.lubrizol.com/cpvc
Lubrizol France SAS — Rouen (Normandy) Industrial Complex →
FRNormandy · manufacturing
Lubrizol France SAS industrial chemicals manufacturing complex in Rouen, Seine-Maritime, Normandy. The Rouen facility is a major European Lubrizol production site for lubricant additives and specialty chemicals (primarily engine oil additives, not CPVC). The Rouen facility gained worldwide attention on September 26, 2019 when a massive industrial fire broke out, generating a large toxic black smoke plume that covered Rouen and surrounding Normandy countryside for days. The fire destroyed warehouses containing approximately 5,000 tonnes of chemicals, caused evacuation orders, agricultural product destruction across Seine-Maritime, and a public health crisis. French authorities investigated criminal negligence. The incident demonstrated that Berkshire Hathaway's Lubrizol — which supplies both CPVC fire sprinkler polymer and lubricant additives — is itself a major industrial fire risk in its European operations.

Did you know2023
Berkshire Hathaway's Lubrizol Corporation holds dominant market positions in two chemistries with distinct critical infrastructure implications that are rarely discussed together: (1) Carbopol (polyacrylic acid polymer, ~80% global market share) — the gelling agent used in virtually all commercial hand sanitizers and many pharmaceutical topical gels; and (2) CPVC compound (FlowGuard Gold / BlazeMaster, ~75-80% US market share) — the polymer compound used in residential hot water plumbing and residential fire sprinkler pipe systems. During the COVID-19 pandemic, both supply chains became simultaneously critical: hand sanitizer demand surged 600%+ (stressing Carbopol supply) while residential construction and fire sprinkler installation continued. A single Berkshire Hathaway subsidiary in Wickliffe, Ohio simultaneously controls the polymer chemistry behind pandemic hand hygiene response AND residential fire safety infrastructure — two critical public health and safety material supply chains concentrated in one company.
Lubrizol Corporation ↗Concentration2023
Lubrizol Corporation (Berkshire Hathaway subsidiary; Wickliffe Ohio) holds a near-monopoly in the US CPVC pipe compound market (~75-80% share) through a mechanism more durable than typical market concentration: Lubrizol controls the fundamental chlorination chemistry patents for making CPVC from PVC resin, and its FlowGuard Gold and BlazeMaster brands are the only CPVC compounds listed by NFPA (National Fire Protection Association) for use in residential fire sprinkler systems under NFPA 13D. The NFPA listing is not just a market preference — it is a regulatory requirement. Any CPVC pipe manufacturer that wants to sell pipe for certified residential fire sprinkler systems in the US must use Lubrizol BlazeMaster compound; no substitution is permitted without a new NFPA listing process that takes years. This creates a permanent regulatory moat for Lubrizol in fire safety infrastructure materials, independent of competitive dynamics. The same CPVC compound used in ~50 million US residential fire sprinkler installations flows through a single Ohio company owned by Warren Buffett.
Lubrizol Corporation ↗Origin2023
Lubrizol Corporation was founded in 1928 in Wickliffe, Ohio — in the industrial belt east of Cleveland that was home to major rubber, steel, and chemical companies. The founding chemists — including Frank Nuzum and colleagues — developed the first commercial multifunctional engine oil additives, a breakthrough in lubricant technology that reduced engine wear and extended oil change intervals. The gasoline engine was only about 20 years old in 1928, and automotive lubricant technology was primitive; Lubrizol's additive chemistry transformed motor oil from a simple commodity into a complex formulated product. The company grew as the global automobile fleet expanded, eventually serving every major oil company and automotive OEM. Berkshire Hathaway acquired Lubrizol in 2011 for $9.7 billion — an acquisition completed despite the resignation of Berkshire executive David Sokol, who had purchased Lubrizol shares before recommending the acquisition to Warren Buffett in a conflict-of-interest incident that became one of the most discussed ethics cases in modern corporate governance. Buffett called Sokol's actions "inexplicable and inexcusable" but completed the acquisition, which added to Berkshire's specialty chemicals portfolio alongside Lubrizol's dominant CPVC pipe compound position and Carbopol personal care polymer business.
