Econo-White 65: Asbestos Pipe Insulation by W. R. Grace

Econo-White 65 was a pre-formed pipe insulation product manufactured by W. R. Grace and Company between approximately 1956 and 1970. Designed for industrial applications, the product was marketed as an economical solution for thermal insulation on piping systems in factories, plants, and other industrial facilities. Like many insulation products of its era, Econo-White 65 contained chrysotile asbestos as a primary component of its composition — a mineral then widely prized for its heat resistance and binding properties but now firmly established as a cause of serious and fatal respiratory disease.

Product Description

Econo-White 65 was part of W. R. Grace’s broader line of industrial insulation materials produced during the postwar industrial expansion period. W. R. Grace was one of the most significant asbestos product manufacturers in the United States during the mid-twentieth century, operating across multiple product categories including spray-applied fireproofing, pipe covering, and block insulation. Econo-White 65 fell within the company’s pipe insulation segment, intended to control heat loss and protect personnel and equipment from high-temperature pipe surfaces in industrial environments.

The product was distributed primarily for use in industrial settings, where large networks of steam, hot water, and process piping required durable thermal insulation capable of withstanding sustained heat exposure. The “65” designation in the product name likely referenced a temperature or density specification relevant to its industrial application, consistent with naming conventions common among manufacturers of that period.

Production of Econo-White 65 spanned the years 1956 through 1970, placing it squarely within the period when asbestos use in American industry was at or near its peak. During this time, regulatory oversight of occupational asbestos exposure was minimal, and the hazards of chrysotile asbestos were not disclosed to workers who handled the material on a routine basis.

Asbestos Content

Econo-White 65 contained chrysotile asbestos, the most commonly used variety of asbestos in commercial and industrial products throughout the twentieth century. Chrysotile, sometimes called “white asbestos,” belongs to the serpentine mineral group and was incorporated into pipe insulation formulations for several practical reasons: it provided exceptional thermal stability, reinforced the structural integrity of formed insulation sections, and was available in large commercial quantities at low cost.

Despite its widespread use, chrysotile asbestos is classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is regulated as a hazardous substance under OSHA’s asbestos standards (29 C.F.R. § 1910.1001 for general industry and 29 C.F.R. § 1926.1101 for construction). Inhalation of chrysotile fibers is documented as a cause of mesothelioma, asbestosis, lung cancer, and other serious pulmonary conditions. These diseases typically carry long latency periods — often 20 to 50 years — meaning that workers exposed to Econo-White 65 during its production years may not have developed related illnesses until decades later.

Pre-formed pipe insulation of the type represented by Econo-White 65 was manufactured by combining asbestos fibers with binders and other materials, then molding the mixture into curved half-sections designed to wrap around piping of specific diameters. This construction method meant that asbestos fibers were integrated throughout the finished product.

How Workers Were Exposed

Industrial workers who installed, maintained, repaired, or removed Econo-White 65 pipe insulation faced direct occupational exposure to chrysotile asbestos fibers. Litigation records document that the handling of asbestos-containing pipe insulation products during this era routinely generated airborne fiber concentrations that exceeded levels now understood to present serious health risks.

Several work activities associated with Econo-White 65 were particularly hazardous. Cutting pre-formed insulation sections to fit specific pipe configurations released asbestos fibers into the surrounding air. Fitting and adjusting sections around valves, elbows, and other pipe fittings required breaking, sawing, or filing the material — each action capable of disturbing and releasing bound asbestos fibers. Workers also faced exposure when removing old or damaged insulation during maintenance or renovation work, as deteriorating pipe covering could shed fibers with minimal mechanical disturbance.

Beyond the primary insulation tradesmen, other industrial workers present in the same spaces were also at risk. Factory maintenance personnel, pipefitters, boilermakers, and general laborers who worked in proximity to pipe insulation activities could inhale fibers that remained suspended in poorly ventilated industrial environments. Plaintiffs in litigation involving W. R. Grace insulation products have alleged that bystander exposure of this kind was common in industrial facilities throughout the product’s years of use.

Critically, litigation records document that during the period Econo-White 65 was manufactured and sold, the hazards of asbestos exposure were not adequately communicated to the workers who handled it. Plaintiffs have alleged that W. R. Grace and other asbestos product manufacturers possessed or had access to medical and scientific information about the dangers of asbestos fiber inhalation but failed to warn workers or provide instructions for safe handling. No effective respiratory protective equipment was routinely supplied or required during the years this product was in use.

W. R. Grace and Company filed for Chapter 11 bankruptcy protection in 2001, in significant part due to the volume of asbestos-related personal injury claims brought against the company. Unlike some major asbestos manufacturers, W. R. Grace’s reorganization process — which concluded with a confirmed plan of reorganization — did not result in the establishment of a traditional Section 524(g) asbestos trust fund of the kind created by companies such as Johns Manville or Armstrong World Industries. As a result, Econo-White 65 is classified as a Tier 2 litigated product for which no dedicated trust fund claim process is currently available.

Individuals who were exposed to Econo-White 65 and have been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease should consult an attorney experienced in asbestos litigation to evaluate the specific legal options available in their circumstances. Litigation records document that claims related to W. R. Grace asbestos products have been pursued through the civil court system, with plaintiffs alleging failure to warn, negligence, and related theories of liability.

Because of the long latency periods associated with asbestos-related diseases, workers exposed to Econo-White 65 during its production years of 1956 through 1970 may only now be receiving relevant diagnoses. Statutes of limitations for asbestos claims vary by state and typically begin running from the date of diagnosis rather than the date of exposure, but timely consultation with legal counsel is essential. Industrial workers with documented exposure histories and confirmed diagnoses are generally encouraged to preserve employment records, medical records, and any product identification information that may support a legal claim.
