Description:
FKM/FFKM B-202 fluoroelastomer is a low viscosity, "B-type"gum polymer that demonstrates improved processing and rheology when compared with existing fluoroelastomers. 
FKM/FFKM B-202 can be blended with other FKM/FFKM types to modify viscosity, enhance processability, and/or improve flow. The applications for FKM/FFKM 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

FKM/FFKM 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 FKM/FFKM. FKM/FFKM B-600 is especially suited to curing with the bisphenol system.
The applications for FKM/FFKM B-600 as below:
• Molded goods, e.g., shaft seals
• Calendered goods, e.g., flue duct expansion joints

FKM/FFKM B-135C and FKM/FFKM B-435C are two Viton precompounds intended for use in molding applications that require bonding to metal inserts. FKM/FFKM B-135C and FKM/FFKM B-435C have a nominal Mooney viscosity (ML 1+10 at 121 °C [250 °F]) of 10 and 40, respectively. Both precompounds have the excellent heat and fluid resistance associated with other FKM/FFKM 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 FKM/FFKM 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 FKM/FFKM terpolymer.By blending FKM/FFKM B-135C with FKM/FFKM 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.

FKM/FFKM 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" FKM/FFKM are needed.
Applications: O-rings, gaskets, and other molded parts requiring properties of a terpolymer "B-family" FKM/FFKM.

FKM/FFKM B-651C is an incorporated cure "B-family"terpolymer that demonstrates improved processing properties and better metal adhesion when compared with older"B-family"terpolymer fluoroelastomers. The improved properties provide excellent compound flow in molding (injection, transfer, compression) bonded parts where the heat and fluid characteristics of a "B-family"FKM/FFKM are needed.The Applications as below:
• Compression, transfer, and injection molding of:
- O-rings and gaskets
- Valve stem and crankshaft seals (and other bonded parts requiring terpolymer characteristics)
• Complex-shaped parts

Overview:
The FKM/FFKM B-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 FKM/FFKM B-Type Fluoroelastomers
The FKM/FFKM 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

FKM/FFKM B-type family products can be blended with other FKM/FFKM fluoroelastomer types to modify viscosity, enhance processability, and improve flow.

FKM/FFKM Terpolymers
FLUOROELASTOMERS WITH BETTER CHEMICAL RESISTANCE
In addition to the heat and chemical resistance offered by all FKM/FFKM fluoroelastomers, the FKM/FFKM terpolymer family offers excellent processing, rheology, and physical properties, as well as significant improvements for resisting chemical attack.
