Recently, I have often received some customers to ask if the hot melt film will melt in the summer. I believe that the customer is basically getting into contact with the hot melt adhesive film, and the understanding of it is not very much. The following Shanghai Hengning TPU hot melt adhesive film will come to answer your doubts!
Hot-melt adhesive film, hot adhesive, can be a very stable solid at room temperature, no adhesion! However, the condition that can produce the adhesive force is to heat it, and then, when it reaches the corresponding temperature and the melting point, it melts to achieve the effect of the bonded article after it is melted, so that it is sure that the hot melt film needs to be heated. Only then can it melt!
It is this condition that the hot melt adhesive film needs to be heated and melted, so that some customers will have the concern that the hot melt adhesive film will melt in summer. Xiaobian can tell you with certainty that the hot melt film will not melt in summer. The melting of the hot melt film occurs only after heating to the corresponding temperature. The melting point of the hot melt film is generally above 90 degrees, and the lower melting point is 80 degrees. Although it is hot and hot in summer, it is far from reaching a temperature that allows the hot melt film to melt.
In addition to concerns about whether the hot melt film will melt in the summer, the adhesion of the hot melt film in summer is also a big problem that many customers will worry about. Customers who do not understand the hot melt adhesive film are prone to such doubts: even if the high temperature in summer does not reach the temperature at which the hot melt adhesive film is melted, the temperature is also high, does it affect the stability of the bond?
Hot melt adhesive film does not need to worry about its stability in summer. Conventional hot melt adhesive film needs to have high temperature resistance and low temperature resistance. Summer high temperature or low temperature in winter does not affect the stability of hot melt adhesive film. of.
From the point of view of the manufacturer of hot melt adhesive film, we can think of the problems that customers can think of, and we need to solve and test when we carry out product development. If the high temperature in summer and the low temperature in winter have certain influence on the stability of hot melt adhesive film, it can only show that the technology of hot melt adhesive film processing is not mature, so it is impossible to promote it to the market.
