Made from 100% high-density polyethylene fibers, lightweight, flexible, particulate-free, and resistant to water, rot, chemical, abrasion and aging, Tyvek is equally strong in wet or dry conditions, has a high strength-to-weight ratio and neutral pH. Applications include mailing envelopes, Tyvek HomeWrap, and maps.
RESOURCES
Tyvek is made from petroleum-based high-density polyethylene (HDPE) strands formed into a sheet, and Titanium Dioxide. A unique flash-spinning process eliminates the use of binders. Local polyethylene recyclers (#2) accept Tyvek, and DuPont provides a system for reclaiming and downcycling used, non-hazmat Tyvek.
ENVIRONMENTAL IMPACT
DuPont does not provide details regarding any byproducts of the Tyvek manufacturing process. However, the company has been involved in several lawsuits regarding drinking water and air contamination, and the production of virgin HDPE is known to produce air and water pollution.
HUMAN HEALTH
Tyvek contains no harmful binders and is chemically inert. It is not known to be dangerous to human health or the environment with normal use. However, if burned, it will release carbon monoxide and carbon dioxide.
SOCIAL EQUITY
DuPont offers STEM-based education programs for young people and provides research grants to untenured faculty around the world.
