PTFE bubble point membrane is generally made from polytetrafluoroethylene (PTFE) suspended powder, which is expanded and stretched to form a microporous film.
Bubble point film has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter, with a pore size range of 0.1μm-0.5μm. This film is laminated on various surfaces using a special process. On the fabric and substrate, it becomes a new type of filter material. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria, achieving the purpose of advanced purification and ventilation. Widely used in pharmaceutical, biochemical, microelectronics and laboratory consumables and other fields.
Suzhou is an environmentally friendly new material manufacturer integrating R&D, production, customization and sales.
During the production process, our company’s PTFE bubble-point membrane can achieve thickness, air permeability, moisture permeability and other parameters through the optimized combination of pressure ratio, speed ratio, operating temperature and other parameters. According to the pore-forming medium and ratio, The void ratio is controlled online to produce high-quality products with different functions and uses to meet the different needs of users.
