VT70BK20 is a 70 shore A black FKM Type GF compound engineered for applications requiring enhanced chemical resistance beyond standard fluorocarbon materials. This material is well suited for O-rings and gaskets exposed to steam, acids, aromatic hydrocarbons, and aggressive industrial media, while maintaining excellent performance in fuels and oils. It offers strong heat resistance, high temperature stability, and durability against ozone, weathering, and aging, ensuring long service life in demanding environments. With a service temperature range of -16°C to 225°C, VT70BK20 meets ASTM D2000 M2HK814 requirements and can be compared to Parker V1274-80 when evaluating equivalent GF-type FKM materials.
FKM, commonly referred to as Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where resistance to heat, fuels, and harsh chemicals is essential. GF-type FKM compounds are specifically formulated to improve resistance to steam, acids, and chemically aggressive environments compared to standard Type A or B grades. These materials are commonly used in chemical processing, oil and gas, and industrial applications where both chemical compatibility and thermal stability are critical. While highly versatile, FKM materials are generally not recommended for certain polar solvents or extreme steam conditions beyond their limits, making proper material selection important.
