Description:
Viton B-202 fluoroelastomer is a low viscosity, “B-type”gum polymer that demonstrates improved processing and rheology when compared with existing fluoroelastomers.
Viton B-202 can be blended with other Viton types to modify viscosity, enhance processability, and/or improve flow. The applications for Viton B-202 as below:
• Transfer and injection molding of complex shapes
• Extrusions (e.g., fuel hose and tubing)
• Solution coatings of fabrics, tanks, or chemical containers
Viton B-600 fluoroelastomer is a gum polymer that demonstrates improved terpolymer processing and lower compound viscosity, along with the excellent heat and fluid resistance characteristics of the “B-family” of Viton. Viton B-600 is especially suited to curing with the bisphenol system.
The applications for Viton B-600 as below:
• Molded goods, e.g., shaft seals
• Calendered goods, e.g., flue duct expansion joints
Viton B-135C and Viton B-435C are two Viton precompounds intended for use in molding applications that require bonding to metal inserts. Viton B-135C and Viton B-435C have a nominal Mooney viscosity (ML 1+10 at 121 °C [250 °F]) of 10 and 40, respectively. Both precompounds are based on 68.5% fluorine gums and have the excellent heat and fluid resistance associated with other 68.5% fluorine Viton terpolymers.
These precompounds contain a proprietary cure system, bonding promoter, and process aid package that has been developed to impart improved processing characteristics over existing terpolymer precompounds like Viton B-651C. They are designed to provide a wide processing window combined with easy mold release and low mold fouling. Typical applications for these materials are valve stem,cam shaft, and crank shaft seals, as well as other metal bonded components requiring the heat and fluid resistance of a 68.5% fluorine Viton terpolymer.By blending Viton B-135C with Viton B-435C, full compounds may be tailored to give the viscosity most appropriate for the production equipment in use (compression, transfer, or injection molding) and tooling geometry.
Viton B-601C is an incorporated cure “B-family” polymer that demonstrates improved processing properties when compared to older “B-family” terpolymer fluoroelastomers.
The improved properties provide excellent compound flow in molding (compressions, injection, transfer) parts, where the heat and fluid characteristics of a “B-family” Viton are needed.
Applications: O-rings, gaskets, and other molded parts requiring properties of a terpolymer “B-family” Viton.
