5. FAQ

Q: Can I know what is PTFE material ?

A: Of course! The most widely recognized brand name for PTFE is Teflon.Let's break down what PTFE is, from a simple explanation to its fascinating details.

Key Properties (Why is it so special?)

• Extremely Low Friction: PTFE has one of the lowest coefficients of friction of any known solid material. This is what makes it so slippery and non-stick. Things just slide right off it.
• Excellent Chemical Resistance: It is almost completely inert. It doesn't react with most chemicals, including strong acids, bases, and solvents. This makes it ideal for containers and pipes in chemical plants.
• High Heat Resistance: It can operate continuously at temperatures up to 260°C (500°F) and for short periods at much higher temperatures without degrading.
• Excellent Electrical Insulation: It is a great electrical insulator, even at high frequencies, making it perfect for wiring in aerospace and computer applications.
• Hydrophobic: It repels water completely. Water beads up and rolls off its surface.
• Non-Toxic: In its solid form, it is biologically inert, which is why it's approved for use in medical implants and food processing equipment.

Q: How to determine whether this PTFE is good or bad ?

A: Here are some tips :

• Color and Purity: High-quality virgin PTFE should be a clean, uniform white. Any discoloration, cloudiness, or inconsistent tones could indicate that the material contains reprocessed scrap or impurities.
• Surface Finish: The surface should be smooth, consistent, and free of defects like cracks, scratches, voids, or burrs. These imperfections can lead to premature wear and tear.
• Dimensional Accuracy: Good PTFE parts will meet precise dimensional tolerances. Use calipers or micrometers to check that the inner diameter, outer diameter, and wall thickness are consistent and match the manufacturer's specifications.
