PO (polyolefin) hot melt adhesives, compared with EVA hot melts, have a wider performance range, higher heat stability, an improved adhesion strength and higher flexibility at cold temperatures. They bond well to nonpolar substrates like polyethylene and polypropylene. Like most types of hot melt adhesives, open times can be formulated between short and long time. And they can also be made with a wide range of melt viscosities, softening points, and tackiness.
