Bayer’s® Durethan Role
Bayer's research team is aiming nylon 6 nanocomposites at cast film. It is referred to as a
hybrid system that uses Nanocor’s clay to reduce OTR by around 50 percent versus
nucleated nylon. “Stiffness of the nanocomposite is doubled, and its gloss and clarity rival
those of a costly high-clarity polyamide film. Anti-blocking properties are also improved”
(Leaversuch, 2001, p. 67). The new film material with nanoparticles unites the advantages
of EVOH and polyamide 6. The embedded particles prevent gases from penetrating the
film and moisture from escaping. Durethan KU 2-2601 is suitable for applications where
conventional polyamides are too permeable and EVOH is too expensive. Bayer’s Durethan
KU 2-2601 makes an ideal candidate as a plastic coating for paperboard juice containers. It
can protect highly oxygen-sensitive package contents, such as orange juice, at a much
lower cost (Bayer, Inc., 2003).
