You can find a ptfe o ring in many machines. They act as sealants and prevent leaking air or fluids from inhibiting the machine’s work. This article will cover the properties of pfte o rings and how they’re manufactured.
PTFE, or polytetrafluoroethylene, is a synthetic polymer that is also known as Teflon. Teflon is the compound used to create the nonstick feature of cookware, windshield wiper blades, and more.
PTFE’s temperature range nonreactivity, water resistance, and low friction make it perfect for O-rings. PTFE o-rings are used in weather-resistant, electrical, and thermal insulation applications. To make PTFE o-rings, they are compressed and sintered into the o shape, instead of “melt-formed”.
Despite their resilient nature, PTFE o-rings do have some mechanical weaknesses. They are vulnerable to or inadvisable to use with high-vacuum seals, low-compression vacuum sealing flanges, and super-heated steam.
However, it is possible to enhance PTFE with other fillers, like carbon, graphite, glass fibers, bronze, and molybdenum disulfide. These fillers add to the o-ring’s chemical and temperature resistance by improving their mechanical strength, durability, and stability.
PTFE is the perfect substance to use in o-ring manufacturing. These small and simple devices provide excellent sealing on any industrial machine you need.
