Once set Polyurethane adhesives do not melt when heated, thermoplastic polyurethanes which do melt have also been made available.

After drying the polymer film is typically tack-free at room temperature. Not only is it stronger than alternative adhesives, but it also works on surfaces those films just aren't compatible with. This is what many of us think of when we think of traditional adhesive tape.

They are differentiated with respect to their crystallization rates, heat-resistance properties, adhesion to specific substrates and solution viscosities. While the tape is cooling after being heated, the adhesive's microstructure begins to crystallize, boosting its overall bond strength significantly. As part of its design, this adhesive only begins to bond when heated to a very specific temperature. Posted by This is a strong bond with an even application and, as we've described, is often used for binding tricky substrates that other chemicals just don't work on. Once the adhesive has had chance to cool down, the chemicals on the tape start crystallizing. Heat activated film brings a range of useful traits to the table, including some of the following: As a leading adhesive across various industries, heat activated films deserve their reputation.
