Tetrafluoroethylene Propylene (TFE/P) o-rings are a copolymer made up of tetrafluoroethylene (TFE) and propylene. TFE/P has excellent resistance to ozone and weathering along with a wide range of chemicals, including acid, base, and steam. A reliable choice for applications that work in tough environments. Applications include Automotive engine coolants, motor oils, some brake fluids, and steering fluids; food and pharmaceutical applications, wide temperature range from -40° C to +200° C with special formulations to 250° C. Disadvantages include high compression set and extrusion resistance especially at high temperatures.
PTFE orings are rigid and offer little elasticity. Low frictions reduces wear and is impervious to many chemicals. It offers good high temperature protection in addition to its high pressure capability. PTFE o-rings can be formulated with fillers to add to the charachteristics needed for your application.
