| Résumé : |
A new styrenic block copolymer (SBC) with a hybrid elastomer composition combining both isoprene and butadiene in the mid-block was unveiled. The polymer is a completely new concept that will broaden the application field of SBCs in hot-melts, resulting in good pressure sensitive adhesive performances and more economical formulations for tapes, labels and non-wovens.
Until now, two families of non-hydrogenated SBC have been widely used in Hot Melt Adhesives (HMA):
- styrene - isoprene - styrene block compolymers (SIS) and
- styrene - butadiene - styrene block compolymers (SBS).
Both families have specific properties and are used in large volumes in their respective application fields. Further, with variable successes, SIS and SBS have also been combined in a single formulation for several reasons. For instance: to make economically attractive packaging tape and disposable non-woven adhesives; to improve the hot-melt stability of adhesives; or to improve label converting (matrix stripping without adhesive threads). |
