Allied Chemical — Plaskon Division
Company History
Allied Chemical Corporation was one of the largest industrial chemical manufacturers in the United States during the twentieth century, with operations spanning synthetic fibers, agricultural chemicals, industrial gases, and specialty polymer compounds. Among its subsidiaries and operating divisions, the Plaskon Division produced thermosetting plastic molding compounds primarily intended for industrial and commercial manufacturing applications.
The Plaskon Division operated during a period when phenolic and urea-formaldehyde molding compounds were in high demand across American industry. These materials were used extensively in the production of electrical components, appliance housings, automotive parts, and consumer goods requiring durable, heat-resistant plastic components. Asbestos fibers were a commonly incorporated additive in thermosetting molding compounds of this era, valued by formulators for their heat resistance, dimensional stability, and reinforcing properties within the cured resin matrix.
Allied Chemical’s broader corporate history includes multiple reorganizations and name changes. The parent company eventually became AlliedSignal Inc. following a 1985 merger with Signal Companies, and AlliedSignal subsequently merged with Honeywell Inc. in 1999. The Plaskon Division’s specific operational timeline within these corporate transitions is not fully documented in public records; however, the division’s asbestos-containing molding compounds were produced and marketed during a period that appears to have extended through approximately the early 1980s, when regulatory pressure and changing industry practices led most manufacturers to reformulate or discontinue asbestos-containing compound grades.
Asbestos-Containing Products
According to asbestos litigation records, the Plaskon Division of Allied Chemical manufactured and sold phenolic molding compounds that plaintiffs alleged contained asbestos as a functional filler or reinforcing agent. Product documentation — including internal compound specification lists — identifies at least five distinct grades of Plaskon molding compound as potentially asbestos-containing formulations.
The documented products include:
Allied Chemical Plaskon Molding Compound (multiple grades) — Court filings document that Plaskon-branded phenolic molding compounds were sold in various formulations to industrial customers throughout the mid-twentieth century. Plaintiffs alleged that at least four separate grades of the standard Plaskon molding compound line incorporated asbestos fibers as part of their filler or reinforcement systems.
Allied Chemical Flastikon B200-106 Molding Compound — According to asbestos litigation records, this specific grade designation appears among documented Plaskon Division products. Plaintiffs alleged that the Flastikon B200-106 formulation, like other grades in the line, was produced with asbestos-containing materials during at least part of its production history.
Phenolic molding compounds of this type were typically supplied as granular or powder-form materials to manufacturers who then processed them through compression molding, transfer molding, or injection molding equipment. The asbestos content in such compounds — where present — was integrated throughout the resin matrix rather than applied as a surface coating, meaning that the fibers were bound within the finished molded part under normal use conditions. However, court filings document that asbestos fiber release occurred during the compounding process itself, during the handling of raw molding powder prior to processing, during machining or finishing of molded parts, and during any grinding, trimming, or deflashing operations performed on cured components.
The specific asbestos mineral types and concentration levels associated with individual Plaskon grade formulations have not been independently verified through public regulatory filings available to this site. Plaintiffs in asbestos litigation have alleged, however, that the fiber content in thermosetting molding compounds of this period was sufficient to create occupational exposure hazards during manufacturing and downstream processing operations.
Occupational Exposure
Workers in several industrial settings faced potential exposure to asbestos fibers associated with Plaskon Division molding compounds during the decades these products were in active use.
Compounding and Raw Material Handling Workers employed at facilities that received bulk Plaskon molding compound in powder or granular form were among those with the most direct exposure potential. According to asbestos litigation records, plaintiffs alleged that the handling, weighing, blending, and transfer of asbestos-containing phenolic molding powders generated visible and airborne dust that included respirable asbestos fibers. This work was often performed in enclosed processing areas without adequate respiratory protection during the 1950s, 1960s, and 1970s.
Molding and Press Operations Press operators who loaded molding compounds into compression or transfer molds, cleaned press equipment, and removed flash or excess material from finished parts were described in court filings as having repeated, sustained contact with Plaskon-type materials. Cleaning of mold cavities and press platens frequently involved scraping, brushing, or blowing out residual compound material — activities that plaintiffs alleged released asbestos-containing dust into the breathing zone.
Machining and Finishing Downstream fabricators who machined, drilled, ground, or otherwise mechanically finished molded phenolic parts faced secondary exposure risks. Court filings document that such operations generated fine dust from the cured resin-asbestos matrix. Workers performing these tasks in the automotive parts, electrical components, and appliance manufacturing industries were identified in litigation as a class of potentially exposed individuals.
Maintenance and Custodial Workers Plaintiffs alleged that maintenance personnel who serviced molding equipment, cleaned production floors, or maintained ventilation systems in facilities using Plaskon compounds were exposed to accumulated asbestos-containing dust as part of their routine work activities.
Industries and Job Sites The range of industries that used phenolic molding compounds in this period was broad. Court filings and product documentation associate Plaskon Division materials with applications in:
- Electrical component manufacturing (switches, connectors, housings)
- Automotive parts production (under-hood components, brake and clutch related hardware)
- Consumer appliance manufacturing
- Industrial equipment component production
Workers in any of these settings who handled, processed, or worked in proximity to Plaskon molding compounds during the period of asbestos-containing formulation — which plaintiffs allege extended through approximately the early 1980s — may have been exposed to asbestos fibers through the mechanisms described above.
The latency period for asbestos-related diseases, including mesothelioma, asbestos-related lung cancer, and asbestosis, typically ranges from 20 to 50 years following initial exposure. This means that workers exposed to Plaskon Division products during the 1950s through early 1980s may only now be receiving diagnoses of asbestos-related illness.
Trust Fund / Legal Status
Allied Chemical’s Plaskon Division falls under Tier 2 of asbestos litigation classification for the purposes of this reference site. There is no publicly documented, dedicated asbestos bankruptcy trust fund established specifically to resolve Plaskon Division claims. Litigation involving Allied Chemical Plaskon products has proceeded, and continues to proceed, through the civil court system rather than through a structured trust fund claims process.
According to asbestos litigation records, claims involving Plaskon Division molding compounds have been brought against entities in the Allied Chemical corporate lineage, and potentially against successor corporations that assumed liability through merger or acquisition. The corporate chain from Allied Chemical through AlliedSignal to Honeywell is a matter of public record, and the allocation of legacy asbestos liabilities within that chain has been a subject of litigation. Individuals and their attorneys should independently investigate the current legal standing of any entity that may bear responsibility for Plaskon Division products.
If You Were Exposed to Plaskon Molding Compounds
If you or a family member worked at a facility that used Allied Chemical Plaskon or Flastikon B200-106 molding compounds and have since received a diagnosis of mesothelioma, asbestos-related lung cancer, asbestosis, or another asbestos-related condition, the following information may be relevant:
- No dedicated trust fund exists for Plaskon Division claims at this time, based on publicly available information. Compensation would likely be sought through direct civil litigation rather than a trust fund claim process.
- An attorney experienced in asbestos litigation can evaluate your exposure history, identify all potentially responsible parties across the supply and manufacturing chain, and advise on the appropriate legal venue and strategy.
- Documentation of your work history — including employer records, coworker testimony, union records, or any surviving product documentation identifying Plaskon compounds at your jobsite — is important to preserving and substantiating a claim.
- Statutes of limitations apply to asbestos personal injury and wrongful death claims and vary by state. Consulting an attorney promptly following an asbestos-related diagnosis is strongly advised.
Because Allied Chemical Plaskon products were distributed across multiple industries and geographic regions, exposure may have occurred at a wide range of facilities throughout the United States. Workers in the electrical, automotive, and appliance manufacturing sectors who can document contact with phenolic molding compounds during the relevant decades should discuss their specific exposure history with qualified legal counsel to determine what remedies may be available.
