Common O-Ring materials that are SUITABLE for dynamic and static seal in the environment containing Benzoic Acid include

  • Chemraz: Chemraz combines the resilience and sealing force of an elastomer with chemical resistance approaching that of PTFE.
  • Fluorocarbon: Fluorocarbon elastomer (FKM) material is also known by its tradename VITON or Fluorel.
  • Neoprene: Neoprene is a homopolymer of chlorobutadiene (CR).
  • Virgin Teflon: Because Teflon is a hard plastic rather than a stretchy elastomer, it is uncommon to see an o-ring that is made entirely of Teflon.

The O-Ring materials below are USUALLY SUITABLE for static seal in the environment containing Benzoic Acid.

  • Fluorosilicone: Fluorosilicone combines excellent low-temperature performance of silicone with improved chemical resistance.
  • Polysulfide: Polysulfide was one of the first commercial synthetic elastomers.

The following O-Ring materials are SOMETIMES OK for static seal but not for dynamic seal in the environment containing Benzoic Acid.

  • Kalrez: Kalrez is the tradename for a perfluoroelastomeric material.

O-Ring materials that are NOT SUITABLE for using in the environment containing Benzoic Acid include

  • Buna-N (Nitrile): Buna-N, also known as Nitrile rubber, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene.
  • Polyacrylate: Polyacrylate (ACM) is a class of copolymer of ethyl and acrylates.
  • Millable Polyurethane: Millable Polyurethane rubber is made from both polyester and polyether polyols.
  • Styrene Butadiene: Styrene-Butadiene rubber (SBR) has properties similar to those of natural rubber.
Additional Information

There is not enough data to determine whether the following common O-Ring materials are suitable for using in the environment containing Benzoic Acid or not.

  • Aflas: Aflas is the tradename for a unique fluoroelastomer based upon an alternating copolymer of tetrafluoroethylene and propylene ("TFE/P").
  • Butyl: Butyl (IIR) is a synthetic rubber, a copolymer of isobutylene and isoprene.
  • Epichlorohydrin: Epichlorohydrin (ECO) has properties similar to nitrile rubber but with better heat and oil resistance as well as better low temperature flexibility.
  • Ethylene-Propylene: Ethylene-propylene (EP) is a copolymer of ethylene and propylene.
  • Hypalon: Hypalon is the traenme of a clasof Chlorosulfonated Polyethylene (CSM).
  • Natural Rubber: Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis.
  • Hydrogenated Nitrile: Hydrogenated Nitrile Butadiene Rubber (HNBR) is also known as Highly Saturated Nitrile (HSN).
  • Cast Polyurethane: Cast Polyurethane exhibits outstanding tensile strength and abrasion resistance in comparison with other elastomers.
  • Silicone: Silicone is a semi-organic elastomer with outstanding resistance to extremes of temperature.
  • Vamac: Vamac is the tradename of a class of Ethylene Acrylic elastomer (AEM).
