Plicast LWI 24G

Manufacturer: Plibrico Company Categories: Pipe Insulation, Refractory Materials Legal Tier: Tier 2 — Litigated Product

Product Description

Plicast LWI 24G was a castable refractory product manufactured by the Plibrico Company, a Chicago-based firm that specialized in monolithic refractory systems for industrial applications. The product belonged to Plibrico’s line of lightweight insulating castables, with the “LWI” designation indicating its classification as a lightweight insulating formulation and “24G” referencing its specific grade and composition within that product family.

Castable refractories of this type were designed to be mixed with water on-site and applied in a fluid or plastic state before curing into a rigid, heat-resistant lining. Plicast LWI 24G was intended for use in applications requiring both thermal insulation and refractory performance — environments where equipment needed to resist sustained high temperatures while minimizing heat transfer and energy loss. These properties made it attractive across a range of industrial sectors, including steel production, petrochemical processing, power generation, and other heavy industries that operated high-temperature furnaces, kilns, boilers, and process piping systems.

Plibrico marketed its castable refractory lines directly to industrial facilities and through contractors who specialized in refractory installation and maintenance. The company built its reputation on monolithic refractory systems — products applied without the use of traditional firebrick — and Plicast LWI 24G was part of that broader product strategy. Because refractory materials required periodic repair and replacement due to the severe conditions they endured, industrial facilities using Plicast LWI 24G would have ordered and installed the product repeatedly over many years of operation.

Asbestos Content

Litigation records document that Plicast LWI 24G contained asbestos as a component of its formulation. Plaintiffs alleged that asbestos fibers were incorporated into the castable mixture to enhance thermal performance, structural integrity at elevated temperatures, and resistance to cracking or spalling during thermal cycling. Asbestos was a widely used additive in refractory and insulating castable products during much of the twentieth century precisely because its fiber structure reinforced the cured material and contributed to its heat-resistant properties.

The specific fiber type or percentage of asbestos content in Plicast LWI 24G has not been independently confirmed in publicly available regulatory records for purposes of this article. However, litigation records document that plaintiffs alleged the product released respirable asbestos fibers during normal handling, mixing, application, and removal — all activities that disturbed the material in ways consistent with fiber release.

Castable refractory products in general were subject to scrutiny under the Environmental Protection Agency’s Asbestos Hazard Emergency Response Act (AHERA) framework and related regulatory actions targeting asbestos-containing building and industrial materials. OSHA’s asbestos standards, codified at 29 C.F.R. § 1910.1001 (general industry) and 29 C.F.R. § 1926.1101 (construction), govern permissible exposure limits and required protective measures for workers encountering materials of this type.

How Workers Were Exposed

Litigation records document that industrial workers encountered Plicast LWI 24G across multiple stages of its use in industrial facilities. Exposure pathways were not limited to a single trade or task; rather, the product’s lifecycle created repeated opportunities for fiber release in shared work environments.

Mixing and Application: Refractory installers and general industrial workers who mixed Plicast LWI 24G from dry bagged material were potentially exposed during the mixing process. Opening bags of dry castable material and combining it with water generated airborne dust that plaintiffs alleged contained respirable asbestos fibers. Workers applying the mixed castable by hand, trowel, or pneumatic gunning equipment were also alleged to have encountered fiber-laden dust and aerosolized material during application.

Curing and Dryout Operations: After placement, castable refractories required controlled heat application to drive out moisture and cure the lining. Plaintiffs alleged that heating operations during this phase could disturb the material and release additional fibers, particularly if the curing process involved direct flame application or rapid temperature increases that caused surface cracking.

Maintenance, Repair, and Removal: Industrial facilities routinely required refractory repair and relining due to wear, thermal shock, and process-related degradation. Workers removing damaged or spent Plicast LWI 24G — by chipping, jackhammering, or other mechanical means — were alleged to have generated heavy concentrations of airborne dust. Litigation records document that maintenance workers, boilermakers, pipefitters, and general industrial laborers who performed or worked adjacent to these tear-out operations faced significant potential exposure.

Bystander Exposure: Workers in nearby trades who were not directly handling the product — including pipefitters, electricians, and other maintenance personnel working in the same confined spaces or equipment interiors — were also identified in litigation records as having been exposed through the settled and re-entrained dust generated by refractory work.

The industrial settings in which Plicast LWI 24G was used — enclosed furnace interiors, boiler rooms, process piping systems, and equipment maintenance areas — frequently lacked adequate ventilation, which plaintiffs alleged compounded fiber concentrations and prolonged worker exposure.

Plicast LWI 24G is a Tier 2 litigated product. No dedicated asbestos bankruptcy trust has been identified in publicly available trust fund records as specifically covering Plibrico Company liability for this product. Individuals who believe they were exposed to Plicast LWI 24G and have subsequently been diagnosed with an asbestos-related disease should consult with a qualified asbestos litigation attorney to evaluate available legal options.

Civil Litigation: Litigation records document that plaintiffs diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, and other asbestos-caused diseases have pursued civil claims in connection with exposure to Plibrico refractory products. Claims have been brought on theories including product liability, failure to warn, and negligent design or manufacture. Plaintiffs alleged that Plibrico knew or should have known of the hazards associated with asbestos-containing castable products and failed to adequately warn workers of those risks.

Potential Trust Fund Claims: Even where a direct manufacturer trust may not be available, workers exposed to Plicast LWI 24G at industrial facilities may have been simultaneously exposed to other asbestos-containing products from manufacturers that have since established asbestos bankruptcy trusts. An experienced asbestos attorney can evaluate the full exposure history to identify all potentially compensable claims across both trust fund and litigation channels.

Relevant Diagnoses: Conditions that may support legal claims arising from asbestos exposure include malignant mesothelioma, lung cancer with documented asbestos exposure history, asbestosis, pleural plaques with functional impairment, and other asbestos-related pulmonary diseases.
