Elastomers
Various materials for every application
The FLUX range offers different variants for nearly every performance requirement.
-
NBR
NBR = Nitrile Butadien Rubber
Synthetic rubber
(synonyms Perbunan® or Buna-N®)- Used with O-rings and diaphragms
- Good resistance against fuels and oils
- Not resistant against solvents
-
EPDM
EPDM = Ethylene Propylene Diene Monomer
Synthetic rubber- Used with O-rings and diaphragms
- Good resistance against alkalis
- Not resistant against fuels, oils or solvents
-
FKM
FKM = Fluoroelastomer (“fluorine caoutchouc” type methylene)
(Synonyms FPM, Viton® or Tecnoflon®)- Used with O-rings and diaphragm
- Good resistance against alkalis
- Widely-used seal material
-
FFKM
FFKM = Perflurorubber type M
(Synonyms Kalrez® or Simraz®)- Used with O-rings
- Very good resistance against acids and alkalis (similar to PTFE)
- Very expensive (factor 10-14 compared to FKM)
-
FEP
FEP = Fluorinated ethylene propylene
Fluorocarbon- Used with O-rings
- Very good resistance against acids and alkalis (similar to PTFE)
- Not very flexible
-
CR
CR = Chloroprene rubber type R
(Synonyms Neoprene® or Chloroprene®)- Used with diaphragms
- Good resistance against oils
- Very flexible
-
PP-EPDM
PP-EPDM = Polypropylene-EPDM-Copolymer
(Synonym Santoprene®)- Used with diaphragms
- Combines the characteristics of PP and EPDM
- Good resistance against alkalis
- Do not use with oils
