Viton Extreme ETP-600S (formerly designated VTR-8710)

Transcription

1 Technical Information made with Advanced Polymer Architecture Viton Extreme ETP-600S (formerly designated VTR-8710) Viton Extreme ETP-600S is an improved processing version of Viton ETP-900, designed to match ETP-900 as closely as possible in terms of fluid resistance. The monomer composition of ETP-600S is virtually identical to ETP-900, but due to an optimized polymer architecture, compounds based on Viton Extreme ETP-600S exhibit the following: Faster cure rates Improved flow at high shear rates Slightly higher tensile strength Improved resistance to compression set Equivalent fluid and chemical resistance Compounds based on ETP-600S can be readily processed in the same manner used for mixing, preforming, and molding conventional fluoroelastomers. Processors will note that compounds based on ETP-600S will typically mix slightly faster, extrude somewhat more smoothly, and exhibit less mold sticking than the same compound based on ETP-900. Product Description Chemical Composition Copolymer of ethylene, tetrafluoroethylene and perfluoromethylvinyl ether, and a cure site monomer Physical Form Sheet Appearance Off-white to tan Odor None Mooney Viscosity, ML Nominal at 121 C Specific Gravity 1.82 Storage Stability Excellent Fluorine, % ~67 Safety and Handling Before handling or Processing Viton Extreme ETP-600S, be sure to read and be guided by the suggestions in DuPont Performance Elastomers technical bulletin Handling Precautions for Viton and Related Chemicals.
