Spauldite Asbestos-Phenolic Laminate

Product Description

Spauldite was Spaulding Fibre Company’s brand for industrial laminates including asbestos-reinforced phenolic grades. Spauldite laminates were produced as sheet, rod, and tube stock at Spaulding’s Tonawanda, New York facility and shipped to customer fabricators throughout the United States.

Asbestos-bearing Spauldite grades were used in electrical insulation, terminal blocks, structural components, gears, and bushings. Downstream machining operations at customer shops — sawing, drilling, milling, turning — released asbestos fiber from the cured phenolic matrix.

Asbestos Content

Litigation records document that Spauldite Asbestos-Phenolic Laminate was alleged to have contained asbestos fiber as a functional filler or reinforcing agent. Asbestos fibers were incorporated into industrial materials of this category to enhance heat resistance, mechanical strength, dimensional stability under thermal cycling, and electrical-insulation properties.

Plaintiffs alleged that asbestos fibers in Spauldite Asbestos-Phenolic Laminate were typically chrysotile, amosite, or a combination thereof — consistent with industry practice for the asbestos era. When the cured material was subjected to mechanical operations (drilling, grinding, sanding, machining, cutting) or when raw material was handled and processed, those fibers could become airborne.

How Workers Were Exposed

Litigation records document multiple exposure pathways for workers who handled Spauldite Asbestos-Phenolic Laminate:

Raw material handling: Workers who received, weighed, blended, or transferred the material in production environments could disturb settled asbestos fibers and generate airborne dust.

Manufacturing operations: Workers operating the production equipment — molding presses, lamination presses, compounding mixers, cutting saws — were exposed during normal operation, equipment cleaning, and routine maintenance.

Machining and finishing of finished material: Secondary operations including drilling, reaming, turning, grinding, sanding, sawing, and routing of Spauldite Asbestos-Phenolic Laminate generated fine dust containing asbestos fibers. These operations were performed by machinists, toolmakers, electricians, and assembly workers who may not have been informed that the material contained asbestos.

Maintenance and tooling work: Maintenance workers responsible for cleaning equipment, servicing presses and mixers, and disposing of accumulated dust in facilities that produced or processed Spauldite Asbestos-Phenolic Laminate could encounter substantial exposure during cleaning and repair operations.

The occupational exposures associated with asbestos-containing industrial laminates and molding compounds are consistent with patterns recognized by OSHA and NIOSH. The latency period for asbestos-related diseases is typically 20-50 years between initial exposure and diagnosis, meaning workers exposed to products like Spauldite Asbestos-Phenolic Laminate during the mid-twentieth century may be receiving diagnoses today.
