| PTFE is regarded as the “King of Plastics” due to its exceptional overall properties that far exceed conventional polymers. It features outstanding chemical resistance, offering an extremely wide service temperature range from -200°C to +260°C, has an ultra-low friction coefficient (~0.04), also exhibits excellent non-stick characteristics, providing superior electrical insulation, has outstanding weatherability and aging resistance. | |||||||||
PTFE is virtually unaffected by almost all chemical media, including:
Strong acids
Strong alkalis
Organic solvents
Strong oxidizing agents
Aqua regia
It maintains excellent stability even under high-temperature conditions, making it widely used in:
Chemical pipelines
Valves
Sealing components
Corrosion-resistant linings
Semiconductor wet-process equipment
PTFE offers an extremely wide continuous service temperature range:
-200°C to +260°C
Melting point: approx. 327°C
Decomposition temperature: above 450°C
It remains flexible even at extremely low temperatures while maintaining excellent chemical stability at elevated temperatures.
Suitable for:
High-temperature sealing
Hot runner systems
Aerospace applications
New energy equipment
High-temperature insulating components
PTFE has an ultra-low coefficient of friction:
0.04
One of the lowest among all solid materials.
Features include:
Self-lubrication
Anti-seizing
Noise reduction
Wear reduction
Commonly used for:
Sliding blocks
Guide rails
Bushings
Bearings
Sealing rings
PTFE has extremely low surface energy, providing:
Non-stick performance
Easy cleaning
Anti-contamination
Anti-fouling properties
Therefore, it is widely used in:
Food processing machinery
Packaging equipment
Mold release applications
Conveyor systems
Anti-stick tooling fixtures
PTFE features:
Extremely low dielectric constant
Extremely low dielectric loss
Excellent high-frequency stability
It is an important material for 5G, high-frequency communications, and the electronics industry.
Applications include:
High-frequency copper-clad laminates
Coaxial cables
Radar antennas
Insulating gaskets
Semiconductor electronic components
PTFE provides:
UV resistance
Oxidation resistance
Aging resistance
Weather resistance
It maintains stable performance during long-term outdoor exposure and harsh operating environments.
The origin of these outstanding properties lies in PTFE’s unique molecular structure:
the extremely strong C-F bond energy and tightly packed fluorine atoms surrounding the carbon backbone form a helical protective structure, giving PTFE exceptional chemical inertness and thermal stability.
