Is EVA hot melt adhesive a thermoplastic adhesive or a thermosetting adhesive?

Is EVA hot melt adhesive a thermoplastic adhesive or a thermosetting adhesive? Many people who are not very familiar with adhesives do not know the difference between thermosetting adhesives and thermoplastic adhesives. These two types of adhesive products have essential differences, and it is precisely because of these differences that they vary greatly in terms of methods and application scopes. So, what are the differences between thermosetting adhesives and thermoplastic adhesives? Here is a brief introduction for everyone.

We know that many adhesives require heating during the bonding process. For hot melt adhesive, heating means melting it. Since hot melt adhesive is solid at room temperature, it can only melt into a liquid state when heated and adhere to the surface of the objects to be bonded.

Thermosetting adhesives also need to be heated during application because under certain temperature conditions, the chemical substances in the components of the thermosetting adhesive will accelerate the chemical reaction and rapidly transform from a linear molecular structure to a network cross-linked structure. Due to the chemical reactions that occur throughout the process, thermosetting adhesives are usually referred to as reactive adhesives.

EVA hot melt adhesive is melted by heating, while thermosetting adhesive is cured by heating. Whether it is hot melt adhesive or thermosetting adhesive, they each have their own advantages and disadvantages and are widely used in their respective fields. Hot melt adhesives are more efficient, and because they are solid at room temperature, they are cleaner and more environmentally friendly.
