ptfe biaxially oriented film for pollution prevention and control
In today’s era, in order to better fight the battle against pollution and strive to achieve high-quality economic development and high-quality ecological environment, ptfe biaxially oriented film has played a huge role.
As early as the mid-18th century, someone discovered the membrane phenomenon, but it was only in the past 50 years that the membrane process was actually applied to the industrial field.
In my country, the membrane industry started in the 1960s. After decades of development, membrane technology has become an emerging and mature chemical separation technology.
Among them, the PTFE biaxially oriented film formed by the biaxial stretching process occupies an important position in film technology.
In the 1970s, the American Gore Company produced biaxially stretched Teflon microporous membranes through mechanical stretching.
Since then, with the improvement of Teflon resin raw material preparation technology and stretching process, the quality of Teflon microporous membrane has continued to improve.
At the same time, Teflon microporous membrane has also been widely used in many high-tech fields due to its excellent physical and chemical properties.
In view of the special properties of this type of product, many countries such as Japan have also conducted research on the preparation technology of biaxially stretched Teflon microporous membranes and the morphological structure of the membranes, and have made good progress.
The porosity of the ptfe biaxially stretched film produced in Suzhou reaches more than 85%, allowing air to circulate smoothly.
The membrane pore size is 0.1-1μm, which can effectively block water droplets, and the waterproof level can reach IPX7 or above.
The membrane has good rigidity, moderate density, and small sound insulation loss.
The product has excellent waterproof performance and can effectively block rainwater.
Excellent breathability, effectively eliminates sweat and maintains human body comfort.
Good wear resistance and washability.
