The surface tension of PTFE composite membrane is small

The English abbreviation of polytetrafluoroethylene is ptfe, also called Teflon. This material is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents and is resistant to high temperatures. Therefore, people often combine ptfe with other materials to obtain polytetrafluoroethylene. Composite membrane.

After lamination, printed matter often suffers from two situations: poor fastness where there is ink or poor fastness where there is no ink. The former also has two phenomena: one is that the inner film is peeled off from the ink. The other is that a large area or all of the ink is transferred to the inner membrane. For example, surface printing ink prints have low peel strength from the inner film because there is wax on the surface of the ink layer, which is very smooth. In addition, the surface tension of the ink layer on the printed matter is small, resulting in poor firmness of the composite film.

Polytetrafluoroethylene composite membrane is prepared through a biaxial stretching process and is commonly known as the “King of Plastics”. This material has a microporous structure with staggered fibers, high porosity, small and uniform pore size, finer molecular weight and cleaner. It has properties such as high temperature resistance, alkali resistance, and hydrophobicity. It is widely used in air filtration, aviation, electronics, electrical appliances, chemical industry, machinery, construction, textile and many other fields.
