Global Engineering And Technology

PTFE (Polytetrafluoroethylene) diaphragms are specialized sealing components used in applications requiring exceptional chemical resistance, flexibility, and durability. They are commonly used in pumps, valves, actuators, and other industrial systems to isolate process fluids while maintaining operational integrity.

Technical Specifications1. Material:

• Primary Material: Virgin PTFE or modified PTFE for enhanced flexibility and strength.
• Reinforcements (if applicable): Fabric backing (e.g., EPDM, neoprene, or other elastomers) to improve mechanical properties and ease of installation.

2. Temperature Range:

• Operating range: -200°C to +260°C.
• Excellent thermal stability for extreme temperature applications.

3. Pressure Range:

• Suitable for pressures up to 16 bar or higher, depending on design.

4. Chemical Resistance:

• Resistant to almost all chemicals, including acids, alkalis, solvents, and gases.
• Ideal for corrosive and aggressive media handling.

5. Thickness and Sizes:

• Thickness typically ranges from 0.25 mm to 3 mm.
• Available in standard and custom diameters for specific applications.

6. Compliance Standards:

• FDA Approval: Suitable for food-grade and pharmaceutical applications.
• Conforms to ISO 9001, ASTM D3294, and other industrial standards.

Applications:

1. Chemical Processing: Isolation of aggressive chemicals in pumps and valves.
2. Pharmaceutical and Food Industry: Ensures contamination-free operations.
3. Water Treatment: Used in diaphragm pumps for chemical dosing.
4. Aerospace and Electronics: Ideal for applications requiring inert and reliable sealing.
