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
