The Science of DuPont™ Tyvek®

DuPont Graphics products take printing to the next level of durability, quality, strength and flexibility. They are designed to easily and affordably meet the requirements of a vast range of printing applications.

DuPont™ Tyvek® brand protective material is a miracle of science from DuPont. It is a family of tough durable sheet products of high-density polyethylene fibers. The sheet is formed first by spinning continuous strands of very fine interconnected fibers, and then bonding them together with heat and pressure.

Tyvek® is white, non-toxic, chemically inert and contains no binders. The non-woven sheet, after bonding, combines a good printing or coating surface, high opacity and toughness to a degree unique among sheet products of similar weight and price.

Tyvek® is produced in two different types, namely 10 and 14. The fibers in Type 10 Style are bonded to form a tough, dense, opaque sheet. The dense packing of the fine, interconnected fibers produces a smooth surface, high opacity and whiteness. The large number of bonds per unit area results in a stable and abrasion resistant surface with a stiffness similar to paper. Fiber bonding of Type 14 is restricted to discrete points in the non-woven sheet, producing a high degree of fiber mobility, and giving the non-woven a fabric-like drape.
