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.
