Problems encountered when using hot melt adhesive film

Problems encountered in the use of hot melt adhesive film. Hot melt adhesive film knowledge explanation. Hot melt adhesive film is a kind of adhesive applied to two materials of the same or different materials. It is in great demand in industry. As a high-tech material with high viscosity, it is reasonable to understand the product characteristics of hot melt adhesive film before buying products. It is also easy to use. Then I would like to share the product features and applications of hot melt adhesive film.


1. What is the material you need to bond? Different materials of hot melt adhesive have different bonding fastness to different materials. No adhesive has greater bonding strength to all materials than all other adhesives. For example, polyurethane has very strong fastness to textile fabrics, while the bonding strength to PE plastic is almost zero.

2. How high can your material withstand heating. For example, if the maximum temperature resistance of your material cannot exceed 130 ℃, you have to choose a hot melt adhesive with a melting point lower than 130 ℃, because if the processing temperature cannot reach the melting point of the adhesive, the adhesive does not melt, and the adhesive force is almost zero.

3. Do you want to consider the softness of the product after bonding? Do you want to consider the application in high or low temperature environment? Is it washed? Do you want dry cleaning? Do you want continuous tensile resistance? If the above requirements are met, the adhesive film with the above corresponding properties shall be selected.

4. If there are many kinds of glue to choose, choose the glue with high cost performance; When your bonding requirements can be met, choose the thinner glue (the thinner the glue, the cheaper the price).
