Expanded PTFE Gasket

Expanded PTFE (ePTFE) Gasket

Product Overview
The Expanded PTFE (ePTFE) Gasket is a soft, microporous sealing material manufactured from pure PTFE resin through a unique expansion process. It combines the excellent chemical inertness and temperature resistance of PTFE with unique flexibility and high compressibility recovery.

Key Features

1. Excellent Sealability: The soft, fibrous, and microporous structure allows it to conform to irregular flange surfaces, creating an effective seal, especially under low bolt stress and low-pressure conditions.

2. Superior Chemical Resistance: Resistant to virtually all aggressive chemicals, including strong acids, alkalis, solvents, and oxidizers.

3. Wide Temperature Range: Suitable for continuous service from -240°C to +260°C, with short-term peaks up to +300°C.

4. Aging Resistance & Long Service Life: Inherently stable PTFE material resists aging, ensuring a long service life.

5. High Flexibility & Recovery: Easy to install and remove, maintaining a good seal even after stress relaxation.

6. Pure Material & Non-Contaminating: Made from 100% PTFE without binders or additives. Clean and non-contaminating, ideal for high-purity industries like food, pharmaceutical, and semiconductor.

Typical Applications

Chemical Processing Equipment: Sealing for pumps, valves, reactors, and flanges.

Food & Pharmaceutical Machinery: Sealing for piping and vessels requiring hygienic standards.

Semiconductor Manufacturing: Sealing for high-purity, contaminant-free vacuum and gas delivery systems.

Energy Industry: Sealing for compressors, heat exchangers, etc.

Precautions

Apply appropriate compression during installation to ensure effective sealing, but avoid over-compression which may damage the structure.

Please select the specific model and specification based on actual service conditions (e.g., pressure, temperature, medium).
