Description:
FKM/FFKM VTR-9209 is a precompound containing an improved "B-type" fluoroelastomer. This precompound incorporates a bisphenol cure system that can be optionally compounded with peroxide and coagent for "dual curing." FKM/FFKM VTR-9209 offers a unique combination of processing and cured characteristics including:
• High quality, smooth extrudate surface and appearance at thickness less than 1.0 mm (0.040 in)
• Excellent "green" strength that helps maintain extrudate shape, as well as enabling draw down to very thin veneer thicknesses
• Excellent fuel permeation resistance
• Good tensile strength
• Good adhesion to other elastomers in multilayer hoses
FKM/FFKM VTR-9209 is especially attractive for use in the manufacture of low permeation fuel and filler neck hose for automotive and small engine applications. It also works well for any hose requiring a thin FKM layer. This product is superior in extrusion processability, compared to many other types of FKM/FFKM, including FKM/FFKM B-202 and B-600 blends.
FKM/FFKM VTR-9217 is a developmental precompound based on a recently developed "B-type"fluoroelastomer (FKM). This precompound incorporates a bisphenol cure system that can be optionally compounded with peroxide and coagent for "dual curing." Superior thin extrusions for fuel and filler neck hose can be achieved. VTR-9217 has a unique combination of processing and cure characteristics, including:
• High quality, smooth extrudate surface, and appearance at thickness below 0.040 in or 1.0 mm
• Excellent "green" strength that helps maintain extrudate shape,as well as enables drawdown to a thickness of 0.008" or 0.2 mm
• Lower viscosity, lower hardness, and better compression set than VTR-9209, the first generation precompound based on the same gum polymer
• Good fuel permeation resistance for a "B-type" FKM
• Compounds show good adhesion and physical properties
Automotive and small engine applications utilizing low permeation fuel and filler neck hose and tubing are expected to find this product most attractive as an affordable material.
