VT70BK21 is a 70 shore A black FKM Type GF compound engineered for FDA compliant sealing applications that require enhanced chemical resistance. This material is ideal for O-rings and gaskets used in food processing, pharmaceutical equipment, and sanitary systems, offering improved resistance to steam, acids, and aromatic hydrocarbons compared to standard FKM grades. It provides excellent heat resistance, high temperature stability, and durability against ozone, weathering, and aging for long service life. With a service temperature range of -16°C to 225°C, VT70BK21 meets ASTM D2000 M2HK710 requirements and delivers reliable performance in regulated and chemically demanding environments.
FKM, commonly referred to as Viton®, is a high performance fluoroelastomer widely used in O-rings and gaskets where resistance to heat, fuels, and aggressive chemicals is essential. GF-type FKM compounds are specifically formulated to improve resistance to steam, acids, and harsh chemical environments while maintaining strong thermal stability. FDA compliant variants are commonly used in food, beverage, and pharmaceutical industries where both performance and regulatory compliance are required. 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.
