0.22 ΜM PTFE Membrane Filters With Optional Support Backing Medical
Grade
PTFE membranes are a type of high-quality polytetrafluoroethylene
filter media that possess inherent hydrophobic properties, which
make them highly suitable for use in various applications where
clean and sterile ventilation is necessary. PTFE membranes offer
numerous advantages in terms of chemical resistance, mechanical
strength, flexibility, and durability. Their superior performance
attributes make them an essential component in many medical devices
and systems, ensuring the highest level of patient care and
protection.
One of the primary benefits of PTFE membranes is their exceptional
chemical resistance. They can withstand extreme pH levels, making
them ideal for use in sterile environments where strong chemicals
and substances are present. This characteristic makes them ideal
for use in surgical procedures, as well as in the production of IV
filters, wound dressings, and other medical devices.
In addition to their chemical resistance, PTFE membranes exhibit
excellent mechanical strength and flexibility. They can withstand
high pressure drop and temperature fluctuations, making them
suitable for use in various medical applications such as gas
separation, filtration, and purification systems.
Another advantage of PTFE membranes is their ability to prevent the
passage of harmful substances through the membrane. Their molecular
structure creates a barrier that effectively blocks foreign
particles and pathogens from entering the medical device or system,
ensuring the safety and integrity of the patient's health.
Furthermore, PTFE membranes medical grade are highly resistant to
degradation and disintegration over time. They can maintain their
performance and functionality even after extended exposure to harsh
conditions, making them a reliable choice for use in various
medical applications.
PTFE membranes from XINNA are available with optional support
backing for improved handling, these membranes are manufactured
using advanced technologies and meet strict quality standards,
ensuring their suitability for various medical applications,

Features of PTFE Membranes Filters
- Hydrophobic
- High air flow rate
- High pressure resistance
- High mechanical strength
- Excellent resistence to strong acids, bases and solvents
- Lot-to-lot quality consistency
Applications
PTFE membrane can withstand a pH range of 1 to 14 which allows them
to resist the corrosive effects of these substances, making them an
ideal choice for handling a wide range of fluids and chemicals,
therefore in the biotechnology and pharmaceutical industries, PTFE
membranes play a crucial role in filtering strong acids and
aggressive solutions used in the production of drugs or other
chemicals. PTFE membranes are also widely used to sterilizing and
venting air and gases to maintain the purity of the environment and
prevent contamination.
