- Tyvek® structure under a microscope
What is Tyvek® made of and what makes it special?
DuPont™ Tyvek® is made of high-density polyethylene fibres, first spun and then bonded by heat and pressure.
Tyvek® is white, non-toxic, chemically inert and contains no binders. It has high opacity and a toughness unique among sheet products of similar weight and price.
It is a very 'green' product being easily recyclable.
