HEPA air filter paper filters PM2.5 fine particles

In recent years, haze weather has occurred frequently, and serious air pollution problems have attracted much attention. PM2.5 fine particles in the air seriously threaten people’s health. PM2.5 fine particulate matter refers to particulate matter with an ambient aerodynamic diameter less than or equal to 2.5 microns. The higher its content in the air, the more serious the air pollution will be.

Data statistics show that our country is a high-value area for PM2.5 pollution in the world. It has a wide range, long duration, and high pollution concentration. In order to solve this thorny problem, many new filter materials have emerged in an endless stream, including HEPA air filter paper.

HEPA air filter paper has excellent temperature resistance and low temperature resistance, with a melting point of 327 degrees Celsius and a decomposition temperature of 415 degrees Celsius. Long-term use within the range of 260℃. But a major disadvantage of PTFE is its immobility at high temperatures F. It will not change from a high elastic state to a viscous flow state when it is above the melting point, and will not flow even if it is heated to the decomposition temperature, which makes it impossible to adopt the molding method of general thermoplastic materials. PTFE has a low thermal conductivity and poor thermal conductivity.

ptfe film manufacturer specializes in the production of HEPA air filter paper. It has a full set of advanced production equipment and technology, and also has advanced clean rooms and The independent composite slitting workshop ensures the production quality of PTFE membrane; the product materials produced 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.
