There are more types of hot melt adhesive films, and the more common ones are EVA hot melt adhesive film and TPU hot melt adhesive film, which are the two most used hot melt adhesive film varieties. In addition, there are PA hot melt film, PO hot melt film, and PES hot melt film. Recently, we received a customer asking us which one of PO hot melt film and PES hot melt film is the best, which is a difficult question to answer and a typical question from someone who doesn't understand hot melt film.
Both PO and PES hot melt films can stick very well or not, depending on what kind of material they are used to stick. As we have said more than once, hot melt film is like medicine, the right medicine can be applied to the disease, and the adhesive can be applied to the material to bond firmly. This is true not only for hot melt films but also for the whole field of adhesives.
Therefore, the stronger question, PO or PES hot melt adhesive film, cannot be answered in itself but can only be answered under specific test conditions, such as when bonding a specific material.
In addition, the hot melt adhesive film on the material bonding and material categories are very related, such as PO hot melt adhesive film and PES hot melt adhesive film are more suitable for bonding metal. Still, most PO hot melt adhesive film or PES hot melt adhesive film itself is also different because the details of the formula control are not the same. The actual bonding effect on specific materials will also be significantly different. This is also needed to pay attention to.
So, from this rigorous point of view, ask PO hot melt adhesive film and PES hot melt adhesive film that firm such a problem, only given the broad category is unable to explain, must be further detailed to the specific product model, to explain the problem.
