Product Description
Sunds Defibrator, the U.S. arm of the Swedish pulp-technology supplier, provided high-consistency refiners, thermomechanical pulping (TMP) refiners, and pressurized headboxes to U.S. kraft, TMP, and newsprint mills from the 1950s onward. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Sunds Defibrator refiners and pressurized headboxes were supplied and serviced with chrysotile asbestos-fabric packing in the shaft stuffing boxes to seal the pressurized, high-temperature stock service, and that the motor-side housing and adjacent steam lines were insulated with asbestos-block lagging to retain refining heat.
According to publicly filed allegations, this asbestos configuration was carried forward across Sunds Defibrator’s refiner and headbox product lines from the 1950s through the early 1980s and appeared in kraft, TMP, and newsprint mills throughout the U.S. Southeast and Pacific Northwest.
