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:The material of the ring seal is a mixture of PTFE and fiberglass. What are its advantages?

A: the PTFE and fiberglass mixture creates a synergistic material that is far more capable than either component alone, offering a unique combination of strength, durability, and resistance to extreme environments.

I can explain it to you briefly in a few points, and you will understand why the prices of products of the same size vary so much.

• Combined Advantage: It has the advantages of both materials.The surface is extremely easy to clean, prevents material buildup, and allows for the easy release of substances. This is crucial for applications like food processing belts, release sheets, and architectural membranes where dirt and snow need to slide off.
• This material can withstand high temperatures and operate in lower environments, greatly improving the working life of the machine.
