Previously, only asbestos could perform well in high-temperature gloves for uses such as foundries, aluminium extrusion, and metal treatment. However, trials have been performed which show that PBI adequately functions as an asbestos replacement. Moreover, a safety garment manufacturer reported that gloves containing PBI outlasted asbestos by two to nine times with an effective cost. Gloves containing PBI fibers are softer and more supple than those made of asbestos, offering the worker greater mobility and comfort, even if the fabric becomes charred. Further, PBI fiber avoids the chronic toxicity problems associated with asbestos because it is processed on standard textile and glove fabricating equipment. PBI also can also be a good substitute for asbestos in several areas of glass manufacturing.
