Advanced Polymer Architecture

                      Viton^® GBL-200S Sheets
A new Advanced Polymer Architecture Viton^® with 68% fluorine, that is peroxide-cured. It is similar to VTR-8650, but with a significantly lower gum polymer viscosity of ~ 25 ML at 121^°C, allowing it to be blended with VTR-8650 to reach intermediate viscosity ranges. Cures exceptionally fast to a high state of cure. Has improved mold release/mold fouling properties compared to Viton^® GBL-200.

                      Viton^® GBL-600S

• Cures exceptionally fast to a high state of cure.
• Shows improved mold release/mold fouling properties compared to Viton^® GBL-900 and 200
• 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^® GBL-900 and 200
• Shows improved water resistance/volume swell in water compared to Viton^® GBL-900 and 200
• Shows excellent compression set resistance with low or no postcure

It is recommended if mixing in an internal mixer to use at least a 70% load factor.

                      Viton^® GBLT-600S

Viton^® GBLT-600S is a one polymer alternative to GLT and GFLT for fuel seals and fuel injector O-rings

• Better low temperature sealing than GRLT...40^°C and below
• Better fuel/alcohol/methanol resistance than GLT
• Current GFLT and GLT auto specs could be combined into one specification

Viton^® GBLT-600S derives additional benefits from new Advanced Polymer Architecture technology

• Physical modulus is low, elongation is high...parts are easier to stretch, more tear resistant in automated assembly equipment
• Cures exceptionally fast to a high state of cure
• Shows improved mold release/mold fouling properties compared to GLT and GFLT
• Shows excellent compression set resistance with little (2 hr at 232^°C) or no postcure

It is recommended to use at least 70% load factor in an internal mixer.

                      Viton^® GF-200S
A new Advanced Polymer Architecture Viton^® with 64% fluorine, that is peroxide-cured. It is a low-temperature Viton^® fluoroelastomer similar to Viton^® GLT-600S, but with a significantly lower gum polymer viscosity of ˜ 25 ML at 121 °C, allowing it to be blended with Viton^® GLT-600S to reach intermediate viscosity ranges. Cures exceptionally fast to a high state of cure. Has improved mold release/mold fouling properties compared to Viton^® GLT and Viton^® GLT-305.

                      Viton^® GF-600S

• 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 Viton^® GF-600S in an internal mixer it is recommended that at least 70% load factor be used.

                      Viton^® GFLT-200S
Viton^® GFLT-200S is a new, developmental 67% fluorine peroxide cured polymer similar to Viton^® GFLT with significantly improved processing and curing characteristics. Viton^® GFLT-200S utilizes a revolutionary new Advanced Polymer Architecture technology designed to deliver a polymer which is a low viscosity version of Viton^®GFLT-600S.

                      Viton^® GFLT-600S

• Cures exceptionally fast to a high state of cure.
• Shows improved mold release/mold fouling properties compared to GLT and GLT 305
• Shows improved mold flow, less shear sensitivity, and lower extruder die swell for a ~65 Mooney FKM
• Shows excellent physical properties with high elongation in either the original or aging tests
• Shows similar to improved heat, fluids, and low temperature resistance compared to GLT
• Shows excellent compression set resistance with little (2 hr at 232^°C) or no postcure

It is recommended if mixing in an internal mixer to use at least a 70% load factor.
