What temperature is generally better for hot melt adhesive film

Hot melt adhesive film is an Apertured Film adhesive with a very good usage rate in today's composite industry. Its environmental protection and high efficiency characteristics are quietly changing the direction of adhesive selection in various industries. Of course, at the same time, it also exposed many problems that need to be solved and further popularized! Looking at this issue from a professional point of view, the statement is actually not very accurate, and it is easy to cause some disputes. The point of controversy is, this question is to ask at what temperature the hot-melt adhesive film has a better melting and bonding effect, or which temperature type of hot-melt adhesive film is better for bonding materials?

At a glance, these two controversial statements seem to be different, but people who really understand can see the difference at a glance. This point of controversy is actually the temperature conditions during the compounding. In layman's terms, it is the temperature at which the temperature of the compounding equipment is adjusted to make the hot melt adhesive film's adhesion to the material reach an ideal state. Of course, this temperature value must meet the temperature resistance requirements of the material, otherwise the material will be damaged due to high temperature.

Therefore, the temperature at which the hot-melt adhesive film is better for fusion bonding is based on the temperature resistance value of the material to be bonded, and then the type of hot-melt adhesive film used is selected according to the requirements of material compatibility. Through these two dimensions, you can basically determine which specification of hot melt adhesive film to use. The next thing to do is actually proofing test! This kind of controversy on understanding is generally common in companies that have just transitioned to a composite process or are preparing to switch to hot melt adhesive films as adhesives. Due to the lack of basic understanding and cognition of thermal adhesives, it is easier to make mistakes in understanding.

The controversial point of this understanding is that it completely ignores the temperature resistance and material compatibility of the material, thinking that the hot melt adhesive film is universal for all materials and only needs to select the appropriate temperature. When you have a certain understanding of hot melt adhesive film, this misunderstanding will actually be resolved! Therefore, "what is the better temperature for hot melt adhesive film", the focus is on the temperature resistance of the material and the compatibility with the hot melt adhesive film.
