Dyneon Fluoroelastomers

3M™ Dyneon™ Fluoroelastomers are used in some of the toughest environments on earth. From high temperature engines to harsh chemicals of semiconductor manufacturing and demanding conditions of oil and gas exploration, Dyneon fluoroelastomers stand up to the most challenging sealing applications.

Dyneon Fluoroelastomers give manufacturers and end users flexibility in choosing materials with the optimal balance of thermal and chemical resistance in addition to sealing strength. Dyneon offers a wide range of options for performance characteristics in extreme environments. This includes excellent retained sealing force, resistance to concentrated sodium chloride, and service temperatures above 250ºC.

  • Excellent thermal and chemical resistance
  • Low permeation
  • Long service life
  • Excellent processability
  • Compatible with a variety of molding and extrusion processes

Applications

Dyneon is used in the following applications and industry:

  • Aerospace – Dyneon was involved in the Apollo 11 launch. In modern aircraft, Dyneon gaskets are used as backup seals for auxiliary power units and other important sealing applications.
  • Automotive – Dyneon can withstand hot-running engines and harsh fuels. Low permeability helps fuel systems meet strict standards for emissions.
  • Chemical Processing – Used in pharmaceuticals, paper manufacturing, and various chemical processing industries. Ideal for fluid handling and environmental control systems
  • Oil & Gas – Dyneon FKM offers reliable sealing in oil & gas processing applications, and can withstand extreme pressure, corrosive chemicals and harsh temperatures.
  • Pharmaceutical & Food Processing – Dyneon provides long-term sealing and protection to meet the high sanitary standards of pharmaceutical and food processing applications.

Types of Fluoroelastomers

  • Dipolymers & Terpolymers – Available with a range of viscosities and cure technologies, 3M dipolymers and terpolymers can be specified to provide a number of advantages over conventional fluoropolymers. Depending on the product and application, benefits may include improved acid resistance, scorch resistance, elongation retention and more.
  • Base Resistant Elastomers (BRE) – 3M™ Dyneon™ Base Resistant Elastomers (BREs) offer improved chemical resistance in basic (high pH) environments such as high-amine automotive oils and lubes, coolants and transmission fluids – making them ideal for many engine, transmission and shaft seals.
  • Low Temperature Fluoroelastomers (LTFE) – In extreme cold, conventional elastomers can shrink, stiffen or crack, and seal failure can seriously damage equipment or vehicle reliability. 3M™ Dyneon™ Low Temperature Fluoroelastomers (LTFE) are designed to keep equipment running even in arctic conditions, with a true dynamic sealing capability that is effective at temperatures as low as -40°C.
  • Perfluoroelastomers (PFE) – Typically used in extreme environments where other elastomer materials cannot perform due to thermal, chemical or purity conditions, 3M™ Dyneon™ Perfluoroelastomers feature the highest degree of purity and chemical resistance in our portfolio. With a temperature range of continuous use up to 315°C, these materials play a critical role in many sensitive aerospace, semiconductor and oil and gas recovery applications.
