1 Tecnoflon FKM and ffkm . portfolio : an overview on standard grades and specialties R. Villa Utrecht, 12-02-2009. Introduction History of FKM- ffkm . 1892: Development of fluroalkanes (Swarts reaction). 1955: Elastomeric copolymer VDF-CTFE ( Kellogg Army). 1956: Copolymer VDF-HFP (Dupont) improved heat stability 1960: Terpolymer VDF-HFP-TFE (Dupont) better chemical resistance 1960s: Perfluoroelastomers - copolymers TFE/PMVE (Dupont). 1960s: Copolymers TFE-P (Dupont, Asahi Glass). 1960: Copo and terpolymers using 1 HPFP instead of HFP (Montecatini-Edison SpA).

2 1970: Bisphenol curing chemistry (Dupont and 3M). 1970s: Terpolymers VDF/TFE/PMVE improved low T performance Late 1970s: Peroxide curing chemistry Br as CSM (Dupont) I as CSM (Daikin).

4 SOLVAY SOLEXIS 2009, SOLVAY Fluoroelastomers applications Automotive industry Aerospace industry Chemical & Processing industry Oil field / Mining Semicon industry SOLVAY SOLEXIS 2009, SOLVAY Fluoroelastomers classification FKMs are classified according to monomer composition and ratio FKMs are manufactured by polymerization of a limited number of monomers: Vinylidene Fluoride (VF2) CH2=CF2. Hexafluoropropylene (HFP) CF2=CF-CF3. Tetrafluoroethylene (TFE) CF2=CF2. Perfluoroalkylvinylether (PAVE) CF2=CF-OCF3 (main monomer MVE when Rf = CF3).

5 Ethylene (E) CH2=CH2. Propylene (P) CH2=CH-CH3. FKMs can be further differentiated by curing chemistry Two main cure systems: Bisphenol Peroxide SOLVAY SOLEXIS 2009, SOLVAY Chemical composition Fluoroelastomers (FKM) are classified according to monomer composition (ASTM D1418): Type 1. VF2, HFP (Bisphenol). Example: Tecnoflon FOR 80HS. Type 2. VF2, HFP, TFE (Bisphenol or Peroxide). Example: Tecnoflon FOR 4391 (Bisphenol). Example: Tecnoflon P 959 (Peroxide). Type 3. VF2, TFE, PMVE (Bisphenol or Peroxide). Example: Tecnoflon PL 855 (Peroxide).

6 Type 4. TFE, P, VF2 (Bisphenol). Type 5. TFE, HFP, VF2, E, PMVE (Peroxide). Example: Tecnoflon BR 9151 (Peroxide). Perfluoroelastomers ( ffkm ) are usually TFE / PAVE (MVE) copolymers SOLVAY SOLEXIS 2009, SOLVAY ! "#. CF3. ( PR4)+ -O O-( PR4)+. CF3. CH2-CH=CH2. $# N. O=C C=O. CH2=CH-CH2-N N-CH2-CH=CH2. C. O.
