Description: VTR-8505 is a new 64% fluorine, peroxide-cured, low-temperature Viton® fluoroelastomer similar to VTR-8500 but with a significantly lower gum polymer viscosity of ~25 (ML at 121°C). VTR-8505 utilizes revolutionary new 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-8500 to reach intermediate viscosity ranges
• Cures exceptionally fast to a high state of cure
• Shows improved mold release/mold fouling properties compared to Viton® GLT and GLT-305
• Shows improved mold flow and less shear sensitivity than 65 Mooney VTR-8500
• Shows excellent physical properties with high elongation, both original and aged
• Shows similar heat, fluids, and low temperature resistance compared to Viton® GLT and GLT-305
• Shows improved water resistance/volume swell in water compared to Viton® GLT and GLT-305
• Shows excellent compression set resistance with either low or no postcure
