Ultraflor Imperial Floor Tile

Manufacturer: Congoleum Corporation Product Category: Floor Tile Years Produced: 1978–1980 Asbestos Type: Chrysotile


Product Description

Ultraflor Imperial was a resilient floor tile manufactured by Congoleum Corporation during the late 1970s. Congoleum, headquartered in Mercerville, New Jersey, was one of the United States’ most prominent producers of resilient flooring throughout the twentieth century, supplying commercial, industrial, and institutional markets with a wide range of vinyl and asbestos-containing floor products.

The Ultraflor Imperial tile was part of Congoleum’s heavy-duty flooring line, marketed primarily toward industrial and commercial settings where durability and resistance to heavy foot traffic were essential considerations. Like many resilient floor tiles produced during this era, Ultraflor Imperial was designed to withstand the rigors of factory floors, warehouses, and large institutional buildings. The tile’s manufacturing window of 1978 to 1980 falls within a period when the flooring industry was beginning to phase out asbestos-containing materials, though many manufacturers, including Congoleum, continued to incorporate chrysotile asbestos in certain product lines during this transitional period.

Congoleum maintained production facilities and a broad national distribution network, meaning Ultraflor Imperial tiles were installed across a wide geographic area during the years they were manufactured and sold. Buildings that received these tiles during the late 1970s and early 1980s may still contain the original installations today, as resilient floor tiles were engineered for longevity.


Asbestos Content

Ultraflor Imperial floor tiles contained chrysotile asbestos, the most commonly used form of asbestos in commercial building products throughout the twentieth century. Chrysotile, sometimes referred to as “white asbestos,” is a serpentine mineral fiber that was prized by flooring manufacturers for its heat resistance, tensile strength, and binding properties. When incorporated into resilient tile formulations, chrysotile helped stabilize the composite material, improve wear resistance, and enhance the tile’s overall dimensional stability under varying temperature and load conditions.

In asbestos-containing floor tiles of this type, chrysotile fibers were typically bound within a matrix of vinyl or asphalt-based binders, fillers, and plasticizers. Under the regulatory framework established by the Asbestos Hazard Emergency Response Act (AHERA), asbestos-containing flooring materials—including vinyl and resilient floor tiles—are classified as asbestos-containing building materials (ACBMs) when they contain more than one percent asbestos by weight. Tiles in this product category commonly met or exceeded that threshold during their era of manufacture.

When Ultraflor Imperial tiles remain intact and undisturbed, the chrysotile fibers are generally considered to be in a bound state. However, when tiles are cut, broken, abraded, drilled, or subjected to aggressive removal methods, the binding matrix can be disrupted, releasing respirable asbestos fibers into the surrounding air.


How Workers Were Exposed

Industrial workers represent the primary trade group documented in connection with Ultraflor Imperial tile exposure. Exposure scenarios arose in several distinct occupational contexts associated with the product’s installation, maintenance, and eventual removal.

Workers involved in the installation of Ultraflor Imperial tiles during the late 1970s and early 1980s may have encountered airborne chrysotile fibers when tiles were scored, snapped, or cut to fit around obstacles, fixtures, or irregular room dimensions. Cutting and trimming resilient floor tiles with knives, saws, or other tools can disturb the asbestos-containing matrix and generate fine particulate debris, including respirable mineral fibers.

Maintenance and custodial workers in industrial facilities where Ultraflor Imperial tiles were installed also faced potential exposure. Routine floor care tasks—including machine buffing, stripping, and the application or removal of floor finishes—can gradually abrade the surface of resilient tiles, potentially releasing fibers over time, particularly as tiles aged and their surface integrity declined.

A significant exposure pathway documented in occupational health literature involves the removal of asbestos-containing floor tiles during renovation or demolition activities. Industrial facilities are subject to periodic refurbishment, equipment upgrades, and structural changes, all of which may have required workers to remove existing floor tile. Dry scraping, mechanical chipping, or the use of rotary equipment to lift aged or adhered tiles can generate substantial concentrations of airborne asbestos fibers if appropriate controls are not in place.

OSHA’s permissible exposure limit (PEL) for asbestos is 0.1 fiber per cubic centimeter of air as an eight-hour time-weighted average, with an excursion limit of 1.0 fiber per cubic centimeter over any thirty-minute period. Floor tile removal and disturbance activities conducted without proper engineering controls, respiratory protection, or wet methods can result in exposures that exceed these regulatory thresholds.

Workers performing these tasks in the decades before comprehensive asbestos regulations were in place, or in workplaces where safety protocols were not rigorously enforced, may have experienced repeated and prolonged exposures to chrysotile fibers without adequate protection.
