DuPont Elastomers GLT305 Peroxide Cured Fluoroelastomer (FKM) Formulation

 

Subcategory: Fluoropolymer, TS; Elastomer, TS; Thermoset

Close Analogs: This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers.

Material Notes:
Formulation
Viton® GLT305100
N990 Carbon Black30
Zinc Oxide3
Diak™ 73
Varox® DBPH-503

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

Information provided by manufacturer.
