PTFE nano mask cloth has very excellent tensile properties. It can be formed and rolled up even after being stretched hundreds of times in both vertical and horizontal directions. Moreover, the minimum thickness of the material can be less than 1um, and it can be rolled up under very low resistance. Get higher efficiency.
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 nano mask cloth is a microporous film made by calendering, extrusion, biaxial stretching and other methods using a special processing technology.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
Three-dimensional mesh structure, no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
It is a high-tech enterprise focusing on the research and development, production and sales of ptfe nano mask cloth. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we produce The products are all produced using imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
And we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
