PTFE membrane filter (hydrophobic)

The products sold in this store are ePTFE (expanded polytetrafluoroethylene) membrane filters, which are high-performance filters with high chemical resistance, heat resistance, and durability. The ePTFE material that composes the filter is derived from the fluororesin PTFE, and is very hydrophobic, so it repels water and aqueous liquids, but the membrane obtained by expanding PTFE forms a three-dimensional porous structure with many fine pores, so air and gas can pass through. In addition, it has good particle capture performance and can be used to efficiently capture or remove fine particles.

ePTFE membrane filters are used in many different industrial fields. For example, they are used in the pharmaceutical, biomedical, electronics, and chemical industries for high-purity gas and solvent filtration, air filtration, chemical liquid filtration, and bioprocessing. They are also said to be suitable for filtration in harsh environments because they can withstand high temperature and pressure conditions. In addition, they are chemically stable, resistant to many chemicals, and non-adhesive, so foreign matter does not easily adhere to the filter surface, making maintenance easy.

In addition to ePTFE membrane filters, our lineup also includes composite membrane filters in which an ePTFE membrane is bonded to a PP nonwoven fabric support.
