Fluorosilicone (FVMQ) and FKM rubber are both high-performance elastomeric materials, often compared using the ASTM D2000 standard for classification and property evaluation. FVMQ stands out for its good heat resistance and resistance to fuels and light oils, making it suitable for low- to medium-temperature environments. Meanwhile, FKM offers higher heat resistance and superior resistance to chemicals and aggressive oils, which is why it is widely used in heavy industrial applications. According to ASTM D2000, FKM typically meets more stringent requirements for thermal and chemical resistance than FVMQ.
