“Olefin-based adhesives are not a new concept,” explains Morel-Fourrier. “They’re widely used in absorbent hygiene products. However, historically, these products had limitations in terms of performance and process friendliness.”
The evolution in catalyst technology brought an increase in polyolefin offerings, with more on-purpose grades proposed for adhesive formulation. Still, according to Morel-Fourrier, these adhesives have had limitations in terms of performance, aging, durability and process friendliness.
“At Bostik, we know it is absolutely possible to achieve both outstanding performance and excellent processability with these newer catalyst technologies,” says Benjamin Funk, senior applied technology chemist in the Global Nonwovens Division of Bostik. During the education session, he told attendees that “formulation and application know-how is essential to successfully implementing the new olefin-based adhesives in the market…an area where Bostik is way ahead of our competitors.”
Bostik already offers the industry’s premier olefin-based adhesive, Relyance. Morel-Fourrier and Funk indicated that an expansion of the Relyance platform would be announced in the near future.
