Superior chemical corrosion resistance Stable over a wide temperature range Ultra-low coefficient of friction + self-lubrication Excellent electrical insulation properties
Resistant to almost all strong acids, strong alkalis, strong oxidants and organic solvents (including aqua regia and hydrofluoric acid); only molten alkali metals and elemental fluorine at high temperature can corrode it. The first choice for chemical anti-corrosion. Continuous service temperature -200℃ to +260℃; melting point 327℃. Long-term use above 260℃ accelerates aging and decomposition; no brittleness at low temperature, suitable for cryogenic conditions. The lowest friction coefficient among solid materials (0.05-0.1), self-lubricating without grease; extremely low surface energy, barely sticks to any material, ideal for food release and sliding parts. Stable dielectric constant, unaffected by frequency, temperature or humidity; commonly used for high-frequency and high-voltage insulation parts.
Extremely low water absorption, aging resistance, and flame retardancy. Physiologically Inert Low Mechanical Strength & Susceptible to Creep High Thermal Expansion Coefficient
Water absorption <0.01%, hardly absorbs water; resistant to UV and ozone, long outdoor service life without aging; UL94 V-0 flame retardant rating with very high limiting oxygen index, difficult to ignite. Pure PTFE is non-toxic and odorless, safe for contact with food and pharmaceutical fluids, meeting food/pharmaceutical equipment requirements. Relatively low mechanical strength and prone to creep; slowly deforms permanently under sustained pressure and cannot bear high loads. Very large coefficient of thermal expansion; dimensions change noticeably with temperature, so expansion gaps must be reserved during assembly.

Application
