Did you know? Masks made using ptfe reusable mask filters have more outstanding performance and effects than some ordinary masks. The editor below will take you to learn about this material.
PTFE is a semi-crystalline polymer. Its crystals are composed of parallel-arranged folded chains to form lamellae, and then the lamellae are accumulated to form a ribbon-shaped polycrystalline polymer. There is a viscous amorphous part between the lamellae and the lamellae.
The interaction between PTFE molecular chains is weak, and the activation energy of the ribbon-like structure to form fibers is only 11.3KJ/mol, which is only several times the ambient temperature. Therefore, under the action of external stress, the ribbon-like structure can easily be pulled out of particles and become micro-particles. Fiber.
PTFE reusable mask filter membrane is made of polytetrafluoroethylene as raw material. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process. , becoming a new type of filter material. The membrane has small pore size (0.05~0.45μm), uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.
PTFE film manufacturer specializes in the production of PTFE reusable mask filters. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; The product materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
