DuPont Mobility and Materials VTR 8605 (GF-S), VTR 8600 (GF-S) 8605/VTR 8600 Blend (discontinued **)
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	VTR-8605 is a 70% fluorine, peroxide-cured, Viton® polymer similar to VTR-8600 but with a significantly lower gum polymer viscosity of ~25 (ML at 121°C). VTR-8605 utilizes Advanced Polymer Architecture technology which includes a new peroxide cure site along with an optimized molecular weight distribution designed to deliver a polymer which: Is ideal for blending with VTR-8600 to reach intermediate viscosity ranges Cures exceptionally fast to a high state of cure Shows improved mold release/mold fouling properties compared to Viton® GF and GF-300 Shows improved mold flow and less shear sensitivity than 65 Mooney VTR-8600 Shows excellent physical properties with high elongation, both original and aged Shows similar heat, fluids, and low temperature resistance compared to Viton® GF-300 Shows improved water resistance/volume swell in water compared to Viton® GF and GF-300 Shows excellent compression set resistance with either low or no postcure VTR-8600 is a new, 70% fluorine peroxide cured polymer similar to Viton® GF but utilizes DuPont Dow's new Advanced Polymer Architecture technology which significantly improves processing and curing characteristics. Advanced Polymer Architecture technology in VTR-8600 upgraded the peroxide cure site along with optimizing the molecular architecture to deliver a polymer which: Cures exceptionally fast to a high state of cure Shows improved mold release/mold fouling properties compared to Viton® GF Shows improved mold flow, less shear sensitivity, and lower extruder die swell for a ~65 Mooney FKM Shows excellent physical properties with high elongation, both original and aged Shows similar heat, fluids, and low temperature resistance compared to Viton® GF Shows excellent compression set resistance with little (2 hr) or no postcure When mixing VTR-8600 in an internal mixer it is recommended that at least a 70% load factor be used.
