Hydrophobic EPTFE Membrane Chemical Compatibility
Hydrophobic EPTFE Membrane exhibits excellent chemical compatibility, making it suitable for diverse industrial and scientific applications. Its inert nature stems from the unique structure of polytetrafluoroethylene (PTFE), which forms strong carbon-fluorine bonds that resist chemical attack.
This inherent stability allows the membrane to interact with a wide range of substances without undergoing significant degradation.
Chemical Resistance Profile
Acids and Bases Compatibility
In contact with most acids and bases, Hydrophobic EPTFE Membrane maintains its structural integrity:
- Withstands strong mineral acids (e.g., sulfuric, hydrochloric, nitric)
- Resists concentrated alkaline solutions (e.g., sodium hydroxide, potassium hydroxide)
- No chemical reaction with pH extremes
Organic Solvents Resistance
The membrane demonstrates exceptional stability with organic solvents:
- Alcohols (methanol, ethanol, isopropanol)
- Ketones (acetone, MEK)
- Hydrocarbons (hexane, toluene)
- No swelling, dissolving, or component leaching
| Chemical Category | Resistance Level | Notes |
|---|---|---|
| Oxidizing Agents | Excellent | Resists hydrogen peroxide, chlorine, etc. |
| Reducing Agents | Excellent | No property compromise under normal conditions |
| Extreme Conditions | Good (with limitations) | Prolonged high heat with reactive chemicals may cause gradual degradation |
Note: While Hydrophobic EPTFE Membrane offers broad chemical compatibility, specific application conditions should always be verified through testing for critical processes.
