Understanding PTFE and EPDM in Diaphragm Applications

A PTFE EPDM diaphragm combines the distinctive properties of PTFE (Polytetrafluoroethylene), known for its chemical resistance and thermal stability, with EPDM (Ethylene Propylene Diene Monomer), valued for its elasticity and flexibility. These materials create a diaphragm that effectively handles extreme temperature fluctuations while providing exceptional chemical compatibility.

PTFE is a fluoropolymer with excellent chemical resistance and non-stick properties. Its low friction and high thermal stability make it ideal for applications involving aggressive media or high temperatures. EPDM is an elastomeric material known for its flexibility, mechanical resilience, and wide temperature compatibility.

Distinction Between PTFE and EPDM

• PTFE:
  • Chemical Resistance: Suitable for aggressive acids, bases, and solvents.
  • Temperature Stability: Operates across extreme conditions, from cryogenic temperatures to high-heat applications.
  • Low Friction: Provides smooth operational performance in valve and pump mechanisms.
• EPDM:
  • Flexibility and Elasticity: Handles dynamic movements without stress or cracking.
  • Resilience: Performs well under mechanical stress and is known for resistance to wear and tear.

Diaphragm Functionality in Valves and Pumps

A PTFE EPDM diaphragm is critical in various industrial valves and pumps. It is positioned as a flexible membrane that ensures effective sealing by responding dynamically to pressure or valve movement changes. This functionality is vital in process medium control, ensuring consistent fluid dynamics and preventing leaks during operation.

Key Features and Benefits of PTFE EPDM Diaphragms

Chemical Resistance

PTFE EPDM diaphragms are renowned for their chemical compatibility, making them suitable for various aggressive environments.
