Characteristics:

1. Excellent corrosion resistance: Expanded PTFE gaskets resist corrosion. You can use them in various corrosive media, such as acids, alkalis, and salts. Corrosion or oxidation will not affect them.

2. Good high-temperature resistance. They can withstand temperatures from -240°C to 260°C. Users can use them in high-heat environments.

3. They seal equipment and prevent leaks. Their performance is excellent.

4. Good stability: They are stable and will not change due to chemicals or other factors.

5. Wide application range: These seals work with various media. Equipment across the chemical, petroleum, pharmaceutical, and food industries uses them.

Application scope:

Expanded PTFE gaskets can withstand high internal pressure. They need only a small preload force. They are perfect for sealing fragile, rough, or uneven glass flanges in areas with temperature changes.

1. Chemical industry: Use expanded PTFE gaskets to seal chemical pipelines, containers, and reactors. They ensure safe equipment operation and prevent leaks.

2. Petroleum industry: Use expanded PTFE gaskets to seal pipelines, valves, and pumps in the oil and gas sectors. They resist oil and high temperatures.
