What is PTFE / Teflon?
PTFE, also known under the brand name TeflonĀ®1, is a soft fluoropolymer mechanical plastic with exceptional resistance to high temperatures, chemicals, corrosion and stress cracking.
PTFE features impressive heat, mechanical toughness, electrical and low friction properties, making it the material of choice for many high heat and low friction applications.
PTFE plastic is available in FDA approved, electrical, mechanical, glass-filled and bearing grades.
Service Temperature:
Excellent resistance to continuous service temperature from -200oC to +260oC .
Chemical Resistance:
PTFE Processes a high inertness towards nearly all known chemicals. It is only attacked by elemental alkali metals, chlorine trifluoride and elemental fluorine at high temperatures and pressure.
Solvent Resistance:
PTFE is insoluble in all solvents up to temperatures as high as 300oC ( 572oF). Certain highly fluorinated oils only swell and dissolve PTFE at temperatures close to the crystalline melting point.
What are some of the standard applications for PTFE?
PTFE is soft and formable, often used for chemically resistant seals and gaskets. With strong electrical properties, PTFE is also used in many aerospace and computer applications. Glass-filled PTFE has enhanced strength and stiffness properties.
