O-Ring Materials
PTFE | Teflon
A material known for its strength for O-Rings: PTFE, also known as Teflon®.
What is PTFE?
PTFE is a polymer known for its unmatched chemical resistance and low coefficient of friction. It is widely used in applications where other materials fail.
Advantages of PTFE
PTFE (polytetrafluoroethylene) is a high-strength polymer known for its exceptional properties, such as low friction, heat resistance and chemical stability. Its versatility makes it an ideal material for a wide range of applications, from non-stick coatings on cookware to industrial components such as gaskets, seals and electrical cables.
Its ability to withstand extreme temperatures and its resistance to corrosion make it indispensable in sectors such as automotive, energy and electronics.
Chemical Resistance:
Almost universal chemical resistance, ideal for contact with acids, bases and aggressive solvents.
High temperature resistance:
Withstands extreme temperatures from -200°C to 260° without losing mechanical properties.
Non-stick properties and low coefficient of friction:
This reduces wear and debris accumulation.
Excellent electrical insulator:
Used in high voltage applications.
Common PTFE Applications
Automotive and Aerospace:
Bearings, seals and washers in environments with high temperatures and exposure to fuels.
Chemical and Pharmaceutical Industry
Internal coatings of pipes, valves and pumps in contact with aggressive fluids.
Food Sector:
Non-stick coatings on food processing equipment.
Limitations:
PTFE is not an elastomer, so its sealing capability is limited, it can be stiff and brittle in dynamic mechanical applications.
