EVA was originally the most widely used raw material for the well-known hot melt adhesives. Polyolefin is often seen as the base polymer of the future for most hot melt adhesives in the packaging and wood industries. Sometimes metallocene hot melts are also discussed. The term metallocene has more to do with the production process of a polyolefin. Thus, a hot melt can be based on polyolefin produced using a metallocene.
Polyolefin has better thermostability, temperature range (resistance) and adhesion range compared to standard EVA raw material. The open time of a polyolefin based hotmelt sometimes also gives the possibility to apply as an alternative to self-adhesive hotmelts for assembly applications.
