Originally EVA is the most widely used raw material for the well-known hot melt adhesives. Now polyolefin is often seen as the base polymer of the future for most hot melt adhesives in e.g. the packaging and wood industry. Sometimes they also talk about metallocene hotmelts. The term metallocene has more to do with the production process of a polyolefin. A hot melt can therefore be based on polyolefin produced with the help of a metallocene.
Compared to standard EVA raw material, polyolefin has a better thermostability, temperature range (resistance) and bonding range. The open time of a polyolefin-based hot melt sometimes also gives the possibility to be used as an alternative to self-adhesive hot melt for assembly applications.
