Air permeability of polytetrafluoroethylene composite membrane

PTFE composite membrane has high peel strength, large air permeability, low resistance, and concentrated pore size distribution It has the characteristics of uniformity and dust removal efficiency of more than 99.99%. It is the most effective and economical new filter material in industrial dust filtration and material recovery.

Composite membranes can be divided into a variety of geotechnical products such as one cloth and one membrane, two cloths and one membrane, one cloth and two membranes, and multiple cloths and multiple membranes. One cloth and one membrane are One layer of cloth and one layer of membrane, two cloths and one membrane, with a membrane in the middle and two layers of cloth on both sides, to prevent the waterproof layer from being damaged by the environment and external forces, thus affecting the anti-seepage isolation effect. Composite geomembranes are generally distinguished by weight. Common ones range from 300g to 1500g. They can also be customized according to the special needs of customer projects.

The polytetrafluoroethylene composite membrane has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter and the pore size ranges from 0.1μm to 0.5μm. This film is made of special The process is laminated on various fabrics and substrates and can become a new type of filter material. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria, achieving high-level Purification and ventilation purposes.

PTFE film manufacturer specializes in the production of polytetrafluoroethylene composite membranes. 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 membranes. ;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.
