Do you know what PTFE mask membrane is? And what is polytetrafluoroethylene? What advantages and performance does it have? What are its uses? Don’t be anxious, please listen to the editor slowly introduce this material to you.
The polytetrafluoroethylene mask film is generally made of 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%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is coated on various fabrics using a special process and base material, it can become a new type of filter material.
The surface of the polytetrafluoroethylene mask membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5.
In addition to the PTFE film mask, it also polymerizes other four layers of protective materials such as PP (polypropylene) and ES (skin-friendly and anti-allergic material). With five layers of protection, the mask is still very light and thin, and the breathing resistance is only 60~70pa, which is much lower than The breathing resistance of traditional N95 masks is 120~250pa.
We have independently developed PTFE films for more than 20 years, with rich experience and mature technology.
The HEPA high-efficiency air filter material has a complete set of technologies, including the preparation and production of the original PTFE film, the patented and innovative film fabric laminating technology, the design and manufacturing of exclusive equipment, and the application development of market products.
Products are widely used in various fields. The company has always implemented the tenet of “quality first, reputation first” to ensure that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
