Rogers Corporation — Asbestos-Containing Phenolic Molding Compound: Legal Rights for Missouri Workers

For Former Workers at Missouri Facilities That Processed Rogers Phenolic Compound

If you or someone you love worked at a Missouri or Midwest manufacturing facility that processed phenolic molding compound during the 1940s through the late 1970s, Rogers Corporation products may be among the principal sources of asbestos exposure responsible for your diagnosis. Missouri’s five-year filing deadline under Mo. Rev. Stat. § 516.120 runs from the date of diagnosis — not the date of exposure. Contact a mesothelioma lawyer Missouri before that window closes.

Urgent Filing Deadline: In Missouri, asbestos-related claims must be filed within five years of diagnosis under Mo. Rev. Stat. § 516.120. That clock is running. Contact an asbestos cancer lawyer St. Louis now — not next month.

Rogers Corporation: A Compound Manufacturer, Not a Molding Shop

Rogers Corporation was one of the major commercial manufacturers of thermosetting phenolic molding compounds in the United States through the peak asbestos era. Rogers did not operate as a jobsite fabricator of plastic parts — it was a raw material supplier whose asbestos-containing compounds were shipped in bags and drums to downstream fabricating shops throughout the Midwest and nationally, where workers processed them into finished molded parts every day.

The significance for asbestos litigation: Rogers is a defendant based on what was in its compound, not on where it operated. Every worker who loaded Rogers phenolic compound into a press hopper, trimmed flash from molded parts, tumbled finished components, or machined or ground a part made from Rogers material potentially inhaled the asbestos fibers Rogers blended into that compound.

Rogers Asbestos Compound Products: RX462 and RX466

Rogers Corporation’s asbestos phenolic compound product line included:

RX462 — Automotive-Grade Asbestos Phenolic Compound

Rogers RX462 was an asbestos-filled phenolic molding compound used primarily in automotive component production, including carburetor caps and related fuel system parts. RX462 was processed at Koller Craft LLC in Fenton, Missouri — one of the Midwest’s oldest custom thermoset molding operations — for carburetor cap production during the relevant exposure era.

Rogers Corporation’s own Material Safety Data Sheet (MSDS), Section II for RX462 expressly states that grinding and machining of RX462 releases asbestos fibers. This admission appears in the compound manufacturer’s own product documentation — making it one of the clearer forms of product-level asbestos disclosure available in phenolic compound litigation.

RX462 was also processed at Carter Carburetor / ACF Industries facilities in the Chicago area, where occupational sampling documented asbestos fiber concentrations from handling and machining RX462. The compound traveled from Rogers through the automotive supply chain into production operations where workers had no meaningful warning of the asbestos content.

RX466 — Industrial and Electrical Applications

Rogers RX466 was another asbestos-containing phenolic compound in the Rogers product line, used for electrical insulation components and general industrial applications. Like RX462, RX466 was shipped to downstream fabricating shops where the compound itself was the asbestos source — not building insulation or secondary materials.

Documented Exposure Concentrations

Occupational sampling studies cited in publicly filed asbestos litigation have documented asbestos fiber concentrations at Rogers Corporation facilities and at facilities processing Rogers compound measured at up to 140 times the then-current OSHA Permissible Exposure Limit (PEL) during compound production, handling, and machining operations. These measurements establish that the work environment created by Rogers phenolic compound processing was not marginally over regulatory limits — it was orders of magnitude more contaminated than what the law permitted.

Crocidolite: The Most Dangerous Fiber in Rogers Compound

Not all asbestos fibers carry equal risk. Amphibole fibers — particularly crocidolite (blue asbestos) — are the fiber type most potently associated with pleural mesothelioma, carrying a substantially higher per-fiber carcinogenic potential than chrysotile (white asbestos).

Rogers Corporation purchased crocidolite fibers from North American Asbestos Corporation (NAAC) for use in certain compound formulations during the relevant period. Durez Plastics and Chemicals — another major phenolic compound supplier — also purchased crocidolite from NAAC during the same era. The presence of crocidolite in Rogers and Durez compounds substantially elevates both the medical and legal significance of exposure at any facility where these compounds were processed.

Workers who processed Rogers RX462 or RX466 at Missouri facilities during the period when crocidolite was incorporated into those formulations may have inhaled the fiber type most strongly linked to pleural mesothelioma — without any warning, protection, or knowledge that the compound they loaded into the press contained blue asbestos from North American Asbestos Corporation.

Sale of the Rogers Compound Business to Fiberite

In approximately 1968–1969, Rogers Corporation sold its specialty phenolic molding compound business — including its customer lists — to Fiberite Corporation, headquartered in Winona, Minnesota. This transaction is significant for asbestos litigation on two levels:

Customer list evidence: The customer lists Rogers transferred to Fiberite document which fabricating shops received Rogers compound — establishing supply chain connections between Rogers and downstream processors like Koller Craft LLC. In documented asbestos litigation, subpoenas served on Fiberite’s successors have sought these records to trace Rogers compound to specific Missouri and Midwest facilities.

Successor liability: Fiberite was subsequently acquired by Cytec Industries. Cytec’s exposure to asbestos liability through the Fiberite acquisition — including liability flowing from the Rogers compound operations Fiberite purchased — has been a subject of documented asbestos litigation involving facilities that received Rogers compound before and after the 1968–1969 sale.

Missouri Facilities Where Rogers Compound Was Processed

Rogers phenolic compounds were processed at multiple facilities within Missouri and the broader Midwest manufacturing corridor:

Koller Craft LLC — Fenton, St. Louis County, Missouri

Rogers RX462 was processed at Koller Craft LLC’s facility at 1400 S Old Highway 141 in Fenton, Missouri for carburetor cap production during the relevant exposure era. Workers who loaded RX462 from bags and drums into compression press hoppers, trimmed flash from finished caps with hand and power tools, placed caps into tumbling machines, and blew compound dust from parts and equipment with compressed air may have been exposed to asbestos fiber allegedly released from the Rogers compound throughout every production run.

The Koller Craft facility operated from 1941 as one of the Midwest’s oldest custom thermoset molding operations. The shift away from phenolic thermoset toward thermoplastic injection molding occurred gradually beginning in the 1960s — meaning the RX462 exposure period spans multiple decades of production.

Square D — Columbia, Missouri

Rogers phenolic compound was used at the Square D Corporation plant in Columbia, Missouri in manufacturing circuit breaker components. Rogers compound was specified for higher-strength products including QO 270 and Q1-2100 breaker configurations at that facility. At Square D’s Cedar Rapids operation, the standard QO breaker used Plenco compound, while higher-strength products used Rogers — a product-line division that maps cleanly onto which workers processed which compound.

Workers at the Square D Columbia plant who operated presses using Rogers compound, performed secondary operations on Rogers-derived molded parts, or maintained equipment contaminated with Rogers compound dust were exposed to the asbestos content of that compound.

Litigation: Rogers as a Named Defendant

Rogers Corporation has been named as a defendant in publicly filed asbestos litigation arising from mesothelioma and asbestos-related disease claims by workers who processed Rogers phenolic compound. The litigation theory is direct product liability — Rogers manufactured and sold an asbestos-containing product, failed to adequately warn downstream processors of the asbestos content and the specific hazards of machining and grinding operations on cured phenolic parts, and those workers subsequently developed asbestos-related disease decades after exposure.

The 140× PEL exposure concentration documented at Rogers facilities, combined with MSDS admissions that machining releases asbestos, and the documented sale of crocidolite-containing compound to Midwest fabricators, creates a substantial evidentiary record in these claims.

Rogers Corporation’s asbestos compound operations predate comprehensive asbestos regulation. OSHA’s first asbestos permissible exposure limit was not established until 1971 — by which time workers had been processing asbestos-laden Rogers compound for decades with no regulatory protection and no meaningful product warning.

Bankruptcy Trusts Available to Missouri Workers

More than 60 manufacturers of asbestos-containing products have established bankruptcy compensation trusts holding billions of dollars for injured workers. Missouri workers who processed Rogers compound and who have been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may have claims against multiple trusts simultaneously, in addition to any civil litigation:

UCC (Union Carbide) Asbestos Trust — Union Carbide supplied asbestos-containing Bakelite compound to many of the same Midwest fabricators that processed Rogers product
Owens Corning / Fibreboard Trust — asbestos-containing materials present in facility infrastructure
Johns-Manville Personal Injury Settlement Trust — pipe insulation and building-system asbestos at manufacturing facilities
W.R. Grace Trust — spray-applied fireproofing present in many industrial manufacturing buildings
Garlock Sealing Technologies Trust — asbestos-containing gaskets on process equipment throughout manufacturing facilities

Trust claims can be filed simultaneously with civil litigation — a dual-track strategy that routinely increases total compensation for Missouri mesothelioma victims.

Missouri’s Five-Year Filing Deadline

Missouri Revised Statutes § 516.120 gives workers diagnosed with mesothelioma or other asbestos-related disease five years from the date of medical diagnosis to file a personal injury claim. This is not the date of first asbestos exposure. It is not the date symptoms appeared. It is the date a physician confirms the diagnosis.

Mesothelioma latency of 20 to 50 years means workers exposed to Rogers compound in the 1950s and 1960s are receiving diagnoses today — and the five-year clock begins running on the diagnosis date.

Contact a Missouri asbestos attorney to evaluate your exposure history, identify all potential defendants including Rogers Corporation and the manufacturers of other compounds processed at your facility, and file every available trust claim before the window closes.

Litigation Landscape

Rogers Corporation has been identified in documented asbestos litigation as a manufacturer of asbestos-containing phenolic molding compounds processed at facilities throughout the Midwest. The compound-specific exposure pathway — where asbestos was blended directly into the raw material rather than applied as building insulation — is well-established in phenolic molding compound litigation and has produced documented recoveries for workers with mesothelioma arising from these exposures.

Other defendants in phenolic molding compound litigation typically include fellow compound manufacturers (Union Carbide/Bakelite, Durez, Monsanto Resinox, Plenco), the downstream facility operators, and manufacturers of asbestos-containing building and process materials present at the fabricating shops. Asbestos bankruptcy trusts established by Johns-Manville, Owens-Illinois, W.R. Grace, Garlock, and others remain accessible to workers with documented exposure at these facilities.

Workers who processed Rogers phenolic compound at Missouri facilities — particularly at Koller Craft LLC in Fenton or at Square D in Columbia — and who have been diagnosed with mesothelioma, lung cancer, or asbestosis should contact O’Brien Law Firm to evaluate their exposure history and available claims.
