Polytetrafluoroethylene (ptfe) was first synthesized and discovered by DuPont in the late 1930s. PTFE flat membranes are widely used in chemical industry, textile, papermaking, aerospace, petroleum, construction, food, medicine, and machinery. It has a wide range of applications in the field of marine operations.
PTFE flat membrane has good heat resistance and self-lubricating properties, and can be widely used as sealing material for high-temperature liquid transportation pipes and corrosive liquid transportation pipes.
For example, pipe joints in the heating industry used to be made of hemp mixed with adhesive. Now they use PTFE film, which can greatly extend the service life.
The PTFE membrane that has been treated to a certain extent has selective permeability, can selectively transmit gas or liquid, and can be used as a separation material.
For example, the film produced by the graft copolymer of TFE and N-vinylpyrrole is a weakly alkaline membrane that can be used as a permeation vaporization membrane for separation and concentration, such as ethanol and dimethylacetamide in concentrated water. The concentration and separation distillation method cannot separate the azeotrope.
After stretching at high temperature and then heat treatment, the ptfe flat membrane produced by calendering can be made into a porous membrane, which can be used for gas-liquid separation, gas-gas separation and liquid-liquid separation, such as argon gas and other Separation of isotopes, separation of chloroform and water, etc.
In addition, this porous membrane can also be used to filter corrosive liquids.
Because the film allows moisture to diffuse but does not allow liquid water to diffuse, it can also be made into ski suits, golf suits, etc. It can maintain the relative humidity of the skin at a certain level.
It is a fluorine material film manufacturer integrating production, sales and customization.
The company has advanced ptfe film production lines and composite production lines.
The company’s products are widely used in various fields. Interested parties can enter the store for consultation.
