Antimony-impregnated graphite withstands 500°C; resin-impregnated graphite is limited to 220°C. This article compares temperature, strength, thermal conductivity, corrosion resistance, and cost to guide high-temperature pump seal and bearing selection.
Carbon graphite is self-lubricating and grease-free; metal alloy seals require external lubrication. This article compares friction coefficient, wear life, temperature and corrosion resistance, and maintenance cost to guide pump and compressor material selection.
PTFE suffers severe creep causing seal-face pressure loss and leakage; carbon graphite is dimensionally stable. This article compares creep rate, thermal conductivity, temperature limit, hardness, and PV limit to guide chemical pump and compressor seal selection.
Silicon carbide conducts 120–150 W/(m·K); tungsten carbide conducts 80–100 W/(m·K). This article compares hardness, thermal conductivity, corrosion resistance, PV limit, and cost to guide mechanical seal mating-face material selection.
