The discovery began when DeSimone realized that PFPE, a material that he had been researching for the Office of Naval Research to prevent marine life from sticking to the bottom of ships, had a similar chemical structure to a polymeric electrolyte commonly studied for lithium-ion batteries.
PFPE is nothing new; it's a polymer that has long been used as a heavy-duty lubricant to keep gears in industrial machinery running smoothly.
polyurethanes described so far are unfilled cast elastomers, not designed for processing and compounding with standard rubber mixing machines and technology.
However, the conventional modified PFPE
have some limitation to improve such properties due to their limited chemical structures and the number of functional groups.
technology delivers exceptional water/oil repellency and soil release for paint and coatings.
above 1% doesn't enhance its effects--but adding some PTFE can.
The spotlight on Solvay s booth D/7/E will be on Fluorolink PFPE
materials that lend specialized functions to products such as anti-ice, easy-to-clean coatings without significant increase of wall thickness, helping to meet advanced targets of efficiency, productivity and sustainability.
According to RTP, compounds with PFPE
require very low (typically less than 1.
A family of perfluoropolyethers, Fomblin PFPE
fluids are reported to be extremely stable in harsh environments and in a wide range of temperatures.
are known for their non-stick and lubricating properties, it has been a major technical challenge to incorporate them into a stable formulation that can lead to a coating with sufficient adhesion to various substrates.
In additio, unlike most traditional fluorosurfactants, PFPEs
do not cause foam formation.
The plans include large capacity increases for PFPEs
sold under the Solvera and Fluorolink brand names, to be progressively implemented during 2008.
