PTFE gaskets, made from polytetrafluoroethylene—a synthetic fluoropolymer—are highly regarded for their exceptional chemical resistance and low-friction properties. Naturally hydrophobic and virtually inert to most chemicals, PTFE gaskets are ideal for use in aggressive environments across a wide range of industries. Their ultra-low coefficient of friction and excellent thermal stability make them especially effective in applications requiring reliable, non-reactive sealing. To improve mechanical performance, PTFE gaskets can be reinforced with fillers such as carbon, graphite, or glass, which help enhance dimensional stability, reduce creep, and improve load-bearing capacity under high pressures and temperatures. They are available in various types, including virgin PTFE, glass-filled, carbon-filled, etched PTFE, and expanded PTFE, each designed to address specific sealing challenges.
