The paper used has a weight of 65 to 90 g/m2 and is made from bleached rag, sometimes with cellulose added, or cellulose.

It is easily machined and does not dissolve in kerosine, gasoline, alcohol, or acetone; however, it is soluble in strong acids, such as sulfuric acid, nitric acid, and hydrochloric acid. Vulcanized fiber is used as electrical and thermal insulation, as a lining material, and as a leather substitute. It may be embossed, stamped, or varnished, depending upon its use. vulcanized fiber
