Cork and Asbestos Pipe Insulation — Keene Corporation (Mundet Cork)

Keene Corporation manufactured and distributed cork and asbestos pipe insulation through its acquisition of Mundet Cork Corporation, exposing industrial workers across multiple sectors to hazardous asbestos fibers. Workers who handled, installed, or worked near these products may be eligible to file claims with the Keene Corporation Asbestos Settlement Trust.

Product Description

Keene Corporation was a diversified industrial manufacturer whose product portfolio expanded significantly when it acquired Mundet Cork Corporation. Through this acquisition, Keene became a producer and distributor of cork-based thermal insulation products, including pipe covering and related insulation systems designed for high-temperature industrial applications.

Cork and asbestos pipe insulation was widely used in industrial facilities, power generation plants, chemical processing operations, shipyards, and similar heavy-industry environments. The material was valued for its combined thermal insulation and fire-resistance properties, making it a common specification in mechanical systems where pipes carried steam, hot water, or other high-temperature fluids. These products appeared in industrial settings throughout much of the twentieth century, during a period when asbestos was routinely incorporated into insulation products with little or no warning to the workers who handled them.

Keene Corporation’s involvement in the asbestos insulation market placed its products in the hands of industrial workers, pipefitters, insulators, maintenance personnel, and others who worked in close proximity to thermal insulation systems. The company’s liability for asbestos-related injuries arising from these products has been established through the creation of the Keene Corporation Asbestos Settlement Trust, which was formed to compensate individuals harmed by exposure to Keene asbestos-containing products, including those manufactured or distributed under the Mundet Cork line.

Asbestos Content

Cork and asbestos pipe insulation products associated with Keene Corporation and its Mundet Cork operations contained asbestos as a deliberate constituent material. Asbestos was incorporated into pipe insulation formulations because of its heat resistance, tensile strength, and its ability to bind with other materials such as cork and various binders to create a durable, flexible insulating product.

Asbestos fibers used in pipe insulation products were typically chrysotile (white asbestos) or amphibole varieties, including amosite (brown asbestos), both of which have been classified as known human carcinogens by the International Agency for Research on Cancer (IARC) and are regulated under OSHA’s asbestos standards (29 C.F.R. § 1910.1001 and § 1926.1101). The Asbestos Hazard Emergency Response Act (AHERA) also identifies all asbestos fiber types as hazardous when friable materials release fibers into the air.

In pipe insulation applications, asbestos content could be significant by weight. As the insulation aged, was cut, damaged, or disturbed during installation or removal, it became friable—meaning it could be crumbled by hand pressure—releasing microscopic fibers into breathing zones. Trust fund documentation and litigation records associated with Keene Corporation confirm the asbestos-containing nature of these products as a basis for established compensation programs.

How Workers Were Exposed

Industrial workers represent the primary exposed population for cork and asbestos pipe insulation products tied to Keene Corporation’s Mundet Cork operations. Exposure pathways were numerous and varied depending on a worker’s specific trade and work environment.

Installation and application created significant exposure risks. Workers who cut pipe insulation sections to fit specific dimensions released concentrated clouds of asbestos-laden dust. Fitting insulation around pipe bends, flanges, valves, and fittings required workers to shape, trim, and manipulate the material by hand, generating repeated fiber releases in enclosed or poorly ventilated workspaces.

Maintenance and repair activities were particularly hazardous. Industrial pipework required ongoing maintenance, and existing insulation had to be removed, broken away, or disturbed to access pipe surfaces. Deteriorated or aged cork and asbestos insulation was often in a highly friable condition, releasing fibers readily when disturbed. Workers performing maintenance in boiler rooms, mechanical spaces, and process areas frequently encountered this material without respiratory protection during much of the product’s period of use.

Bystander and general industrial exposure affected workers who were not directly handling the insulation but who worked in the same areas where installation or removal was occurring. In industrial facilities, multiple trades often worked simultaneously in confined spaces, meaning that fiber releases from one trade’s work could expose nearby workers at elevated concentrations.

Demolition and renovation of older industrial facilities has continued to expose workers into more recent decades. Buildings and industrial systems constructed during the period when Keene and Mundet Cork products were in use still contain asbestos pipe insulation, creating ongoing exposure risks for demolition contractors, renovation workers, and remediation specialists.

Medical conditions documented in connection with asbestos exposure from products like cork and asbestos pipe insulation include mesothelioma, asbestos-related lung cancer, asbestosis, and other pulmonary diseases. These conditions typically have latency periods of ten to fifty years between initial exposure and diagnosis, meaning workers exposed decades ago may only now be receiving diagnoses.
