Polytetrafluoroethylene (ptfe) was first synthesized and discovered by DuPont in the late 1930s.
PTFE microporous membranes are widely used in chemical industry, textile, papermaking, aerospace, petroleum, construction, food, medicine, machinery and marine operations.
With the continuous development of society, people’s requirements for air filtration are gradually increasing, and the continuous improvement of the quality of life is also prompting the upgrading of air filters. Among these air purification equipment, it is indispensable The material is polytetrafluoroethylene microporous membrane.
PTFE microporous membrane is a polymer compound made of tetrafluoroethylene. It is a microporous membrane made by calendering, extrusion, biaxial stretching and other methods using a special process.
It can effectively intercept dust particles in the air, and the material has strong hydrophobicity, non-adhesion, corrosion resistance, thermal stability and good mechanical properties, so it can be washed with water to restore performance, achieve reuse, and greatly extend the use longevity and cost savings.
Conventional filter materials carry dust that is easily adhered to, and the dust is not easy to fall off during cleaning, resulting in low dust cleaning efficiency and short-term dust emission.
Because the pore diameter is tens of thousands of times that of water molecules, it is hundreds of times smaller than water droplets.
The polytetrafluoroethylene microporous membrane has high porosity and low filtration resistance, which will not cause too much filtration resistance to the composite filter material.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
Our company can customize according to user’s requirements.
The key to the technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
