Permeaflon® from Berghof consists of pure, porous PTFE, a material known for its outstanding properties. It is nearly resistant to all chemicals and media, which is particularly important in the medical field where cleanliness and purity are of utmost priority. Furthermore, Berghof’s porous PTFE undergoes a sintering process where it is heated to over 300°C. This process provides the material with the highest temperature and shape stability, making it unrestrictedly usable in autoclave processes. Another special feature of Permeaflon® arises from its unique manufacturing process, the isostatic compression of the raw material. This step gives our filter media, which offer both surface and depth filtration functions, their homogeneous pore structure for consistent filtration efficiency. By being surface-modified or enriched with functional additives, the functionality of Permeaflon® in terms of performance and durability can be further optimized. Thus, Berghof offers high-quality, durable and reliable products that meet today’s requirements.

In the healthcare industry, innovative packaging solutions are crucial in protecting against infection. Our sterile barrier solutions made from porous PTFE play a key role in efforts to prevent infections and protect operating and treatment areas from the entry of unwanted germs.
PTFE is often used as a filter solution in medical packaging, particularly for surgical instruments and equipment. Due to its outstanding hydrophobic properties and chemical resistance, it provides an effective sterile barrier against microorganisms and particles, maintaining the sterility of the packaging. Our commitment to quality, innovation and patient safety is reflected in every solution we provide.

In the packaging, transportation and storage of surgical and dental instruments, traditional container systems rely on disposable filters for steam sterilization. Reusable filters made from Permeaflon® offer a sustainable alternative. Made from medical-grade, sintered PTFE, they are temperature-resistant and serve two crucial functions in steam sterilization: they ensure continuous pressure equalization during repeated sterilization cycles and form a germ barrier for subsequent storage. Permeaflon® permanent filters are free from animal-derived additives and comply with USP Class VI requirements. Additionally, they provide greater convenience and cost savings compared to traditional disposable filters, as the need for replacement by the end customer is eliminated. Decide for improved efficiency and sustainability in sterilization with reusable filters made from medical-grade PTFE by Berghof.
