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
