Product Description
Viton? GBL-200S, formerly known as VTR-8655, is a next generation, easy processing, low viscosity, peroxide cured 68% fluorine fluoroelastomer based on new Advanced Polymer Architecture technology. Compared to the original Viton? GBL-200, Viton? GBL-200S shows better processability coupled with similar or improved fluids resistance in aromatic hydrocarbons, alcohols, water, steam, and acids.
Features
? Is ideal for blending with Viton? GBL-600S to reach intermediate viscosity ranges
? Cures exceptionally fast to a high state of cure
? Exhibits improved mold release/mold fouling properties compared to Viton? GBL-900 and Viton? GBL-200
? Exhibits improved mold flow and less shear sensitivity than 65 Mooney Viton? GBL-600S
? Exhibits excellent physical properties with high elongation, both original and aged compounds
? Exhibits similar heat, fluids, and low temperature resistance compared to Viton? GBL-200
? Exhibits excellent compression set resistance with little (2 hr) or no postcure either low or no postcure
Processing
A load factor of >70% for internal mixing of Viton? GBL-200S is recommended. The recommended process aids for Viton? GBL-200S are 1 phr of Struktol? HT 290, or combinations of 0.5 phr Armeen? 18D with carnauba wax or Struktol? WS 280. Diak? #7 (TAIC) co-agent is recommended for all Viton? GBL-200S compounds. Used at a level of 2.5 phr or less is satisfactory unless high modulus is needed. At higher levels, TAIC can bleed out and cause molding flaws.
Safety and Handling
Before handling or processing Viton? GBL-200S, be sure to read and be guided by the suggestions in DuPont technical bulletin “Handling Precautions for Viton? and Related Chemicals.”
