Overview
Emflon™ PTFE membrane sheets and rolls are hydrophobic in nature and are effective barriers to microbes and particulate matter. The high titer reduction and water intrusion pressures allow the membranes to repel high surface tension liquids while venting gases.
- PTFE membranes are used in a variety of applications such as vents of closed systems, sensors, and electronic equipment.
- These membrane grades serve as a hydrophobic barrier and reduce the risk of particulate contamination in gas streams.
- Material characteristics include broad chemical compatibility and excellent particle retention.
- These supported membranes offer easy handling and are compatible with the following sealing methods: adhesive, insert molding, mechanical, radio frequency, and ultrasonic.
- Compatible with sterilizing methods, such as ethylene oxide and steam (autoclave). If gamma or e-beam sterilization is preferred, consider other products such as the Versapor RC membranes or Hydrophobic Glass Fiber media.
- These membranes are laminated to a non-woven polyester support material, giving the membrane excellent handling and machining characteristics.
- The wide chemical and temperature compatibility and compliance with United States Pharmacopeia (USP) Biological Reactivity Tests, In Vivo <88> for biosafety ensures robust performance in critical venting applications.
Custom roll, sheet, and disc sizes available upon request. Please contact your local sales representative for additional information.
