0.45 Micron Reinforced PTFE membrane filters for Biomedical Devices

Polytetrafluoroethylene (PTFE) filter membranes are a common material used for implants and medical devices in general because of its high biocompatibility and inertness. PTFE Membrane possesses natural hydrophobic properties, making it an excellent choice for applications such as filtering gases, aqueous aerosols, protecting vacuum pumps, or sterile venting fermentation tanks. The membrane's ability to prevent aqueous aerosols from entering the system ensures that the air being vented is free from contaminants, providing a safer and more hygienic solution for various industries such as pharmaceutical manufacturing. PTFE membranes can be utilized to protect pumps and machinery from aqueous aerosols by effectively blocking these particles from entering the system, these filters help maintain the integrity and performance of pumps and other equipment. One unparalleled advantage of PTFE membrane filter is their ability to withstand much higher water intrusion pressures than other types of filter membranes, this is an essential factor to consider for in-line filtration applications.

PTFE membranes from us are bi-axially stretched (expanded) with uniform pore size, high porosity which effectively retain microbes and particles in the air. And given the sensitive nature of PTFE, the membrane filters are reinforced and laminated with a polypropylene backing for higher mechanical strength and easy handling, which significantly extends their medical and biotech applications. The PTFE membrane filters from us are generally available in the form of rolls, which can be punched to the desired size and formats as per requirements to ensure optimal performance across a wide range of applications.
