Improved Processing Fluoroelastomers with Additional Benefits
The Viton™ B-type and F-type families of fluoroelastomers are a new generation of terpolymers offering:
- Improved processing
- Increased mold flow
- Excellent mold release
- Improved extrusion performance
Superior Rheology Properties with Viton™ B-Type Fluoroelastomers
The Viton™ B-type family of fluoroelastomers are terpolymers used in applications where improved processing and rheology is needed. This can include:
- Transfer- and injection-molding of complex shapes
- Fuel hose and tubing extrusions
- Solution coatings of fabrics, tanks, or chemical containers
Viton™ B-type family products can be blended with other Viton™ fluoroelastomer types to modify viscosity, enhance processability, and improve flow. The product is offered in two grades:
- Viton™ B-202
- Viton™ B-600
The “2” versus “6” is based on a measure of the polymer’s viscosity, which determines rubber processability. (Viscosity is measured at a specific temperature using the Mooney viscosity determination.)
Fuel Resistance Using Viton™ F-Type Fluoroelastomers
The Viton™ F-type family of fluoroelastomers are a new generation of terpolymers ideal for sealing applications requiring permeation resistance to fuels.
Viton™ F-type fluoroelastomers are used widely for compression and transfer molding of seals, gaskets, and O-rings that require excellent fluid resistance. Such fluid resistance is critical in automotive applications where parts are exposed to automotive fuels.
In addition to heat and chemical resistance characteristics, Viton™ F-type fluoroelastomers offer significant improvements in processing, rheology, and physical properties. The product is offered in one grade: Viton™ F-605C.
