PO Hot Melt Adhesives

Compared with EVA hot melts, polyolefin-based (PO) hot melt adhesives offer an altogether wider performance range – higher heat stability, an improved adhesion spectrum or high flexibility at cold temperatures, for instance. Depending on the formula, open times can vary between very short and very long. The group of PO-based hot melts is also the type that is most frequently used for bonds in spray application.

Meanwhile, adhesives made using Metallocene technology (BÜHNEN avenia) are widely applied in the packaging industry. This type of PO-based hot melts shows a far better performance compared with simple EVA hot melts .
