The Science of Tyvek® and Tychem®
Tychem® and Tyvek® garments are tested against a broad range of hazardous materials to determine permeation and penetration which is critical for fabrics that are exposed to hazardous chemicals or particulates. Permeation occurs when a chemical is absorbed until it saturates one side of the material and then desorbs, or diffuses, to the other side of the material. Penetration tests are used to determine whether or not a fabric will leak or be able to block the passage of a particulate or chemical. By developing fabrics that pass these tests, DuPont helps protect first responders and industrial workers from hazardous liquids, vapors, gases and particulates.
