Description of key information
Additional information
Galden LMW is a multi-constituent substance consisting of low molecular weight perfluoropolyethers (PFPE). Two grades of Galden LMW are manufactured (Galden HT55 and HT70), which contain the same perfluorinated constituents and differ only in the relative concentration of the constituents.
Since the chemical composition of the two grades is the same, most of the chemical and physical properties of the two grades have the same order of magnitude or, even, they are identical.
Observed differences are due to the difference in the relative concentration of the components.
When a difference in numerical values is observed (or calculated) between Galden HT55 and Galden HT 70, for risk assessment purpose the average value has been set as key value.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
