A Successful History
1934 • Hoechst AG files patent for CTFE polymerization
1957
• 3M purchases Chemical Manufacturing Division from M.W. Kellogg Co. (fluoropolymers)
1987
• Hoechst begins toll manufacturing of fluoroelastomers latex for 3M
1996
• Dyneon formed as joint venture between 3M and Hoechst AG
1999• Dyneon becomes wholly owned 3M subsidiary

What are Perfluoroelastomers?
PTFE
FKM
FFKM
Fully fluorinated backbone %F ~= 72 Wt%The C – F bond strongest in organic chemistry
The C - H bond is the weak link (for heat and esp. for chemical resistance)

Major Benefits of Perfluoroelastomers
Superior chemical resistance
(Elastomeric PTFE)
… leads to low swell � long service life
Higher temperature resistance up to 320°C
… less degradation � long service life
