PTFE vs elastomer sealing
PTFE excels in chemical resistance and low friction; elastomers (NBR, EPDM, FKM) excel in resilience and compression set in many dynamic seals. Selection depends on media, temperature, and motion.
Hybrid approaches
Filled PTFE and engineered plastics bridge wear and load requirements. For ball valve trim, compare PTFE balls with elastomer ball options.
