In the actual production and application of medical ePTFE film, it is inevitable to encounter the problem of difficult bonding. Why is this product difficult to bond? Can the problem of using plasma cleaning machines be effectively solved? Medical ePTFE membrane is a new type of polymer material, which is made of polytetrafluoroethylene resin through expansion, stretching and other processes, so it is also called polytetrafluoroethylene expanded membrane. Like other PTFE materials, medical ePTFE membranes also have some bonding problems during the bonding process. So why is it difficult to bond medical ePTFE membranes? Can't be solved with plasma cleaning machine? Due to its excellent performance, PTFE medical films are widely used in biomedical fields such as artificial blood vessels and heart patches. But for the bonding of expanded polytetrafluoroethylene ePTFE, everyone should have a headache. First, we must understand the reasons for the difficult bonding of medical ePTFE films. Reasons for difficult adhesion of medical ePTFE films: The medical expanded polytetrafluoroethylene ePTFE film is generally 4-12mm thick and needs to meet different practical requirements, so it is usually laminated with different thicknesses of film layers, or bonded with other medical materials to form a certain Thickness of the sheet. Moreover, the bonding effect will be affected by factors such as material characteristics, adhesive composition, temperature, etc., and usually cannot meet the bonding and use requirements, that is, the phenomenon of difficult bonding. The phenomenon of difficulty in bonding is mainly caused by the following reasons: 1. It is difficult to adhere between ePTFE membranes, and the use of complex adhesives will cause damage to the product; 2. The microporous structure of the ePTFE membrane is formed by stretching under heating conditions. When the temperature reaches a certain level, the micropores will shrink or even disappear; 3. When the temperature rises, the ineffective components in the chemical binder will be removed. Regarding whether the plasma cleaning machine can solve the adhesion problem of the ePTFE membrane, after repeated experiments and tests, the plasma cleaning machine can process the ePTFE membrane by selecting a non-reactive gas. In addition to effectively improving the adhesio
