PTFE filter element, namely polytetrafluoroethylene filter element. The material of the filtration layer of the filter element is polytetrafluoroethylene membrane. The SR process gas filter with a body made of stainless steel has PTFE filter elements installed inside. We can select hydrophilic PTFE filter elements or hydrophobic PTFE filter elements according to the filtration requirements of users.

Polytetrafluoroethylene (PTFE) has unique low surface energy and relatively small surface tension. Its molecular chains are hydrophobic, making PTFE a typical hydrophobic material. PTFE is widely used in waterproof materials, anti-fouling coatings, anti-sticking coatings, and the field of corrosion prevention. In addition, it also plays an important role in multiple fields such as building materials, textile fabrics, and food packaging. It is worth noting that although PTFE is inherently hydrophobic, under specific conditions, such as through surface treatment or the addition of hydrophilic fillers, it can also exhibit hydrophilicity. This enables PTFE to have broad application prospects in fields such as medical devices, biomaterials, and electronic devices that require both hydrophobic and hydrophilic properties simultaneously. The imported brand PTFE filter element installed inside the SR process gas filter has wide chemical compatibility, good corrosion resistance, oxidation resistance, heat resistance, high flux, low differential pressure, and long service life. The 100% integrity test ensures that the filter has good bactericidal effect and high-quality filtration performance.

Equipped with different types of PTFE filter elements, the SR process gas filter can be used for sterilization of compressed air, nitrogen, fermenter, as a breathing filter, air filtration for aseptic packaging, sterilizing filtration of solvents and cosolvents, filtration of strong acid and alkali liquids, filtration of strong oxidizing liquids, filtration of high-purity chemicals, filtration of biological reagents, etc.
