DuPont Zonyl® Products

Some DuPont Zonyl® Products may contain the following monomers which have been registered under the REACH legislation. TFE and Ethylene Oxide have been registered as monomers of various polymers.

Monomer CAS # EC #
TFE (Tetrafluoroethylene) 116-14-3 204-126-9
Ethylene Oxide 75-21-8 200-849-9

DuPont Zonyl® Products exist as substances and polymers. The polymers themselves are not subject to registration and therefore their SDS include neither registration numbers nor exposure scenarios for these monomers.

Some DuPont Zonyl® Products may be considered mixtures. These mixtures may contain polymers, monomers and substances which have later registration dates.

These products may also contain substances for which DuPont is considered a Downstream User (DU). More information on the registration status of these substances (registration numbers, uses, etc.) will be communicated in our SDS.
