Kraton Polymers LLC announced the commercial availability of a new Kraton SIBS (Styrene-Isoprene-Butadiene-Styrene) polymer grade, for use in hot melt adhesive labels. This new grade has been designed specifically for label applications and offers economic and performance advantages over other conventional technology grades.
This unique polymer exhibits outstanding adhesive properties with an excellent balance of tack, peel, shear adhesion, and resistance to flagging in even the most demanding label applications. Like other SIBS polymers, this new grade is compatible with both isoprene and butadiene based SBCs and therefore can also be used in combination with SB diblock. It is also useful for improved tack at lower temperature for food packaging and applications requiring a broader service temperature range.
High diblock content and a unique polymer structure make this new label grade SIBS easy to convert into labels, including improved die-cutting compared to SIS based polymers. It further offers excellent compatibility with a wide range for formulating ingredients including tackifying resins, plasticizers, fillers and additives.
“Kraton is dedicated to supporting our customers by developing customized and innovative solutions targeted at both improving functional performance as well as reducing total system cost”, Jim Smith, Global Vice President and General Manager for Kraton’s Adhesives, Sealants & Coatings said “We are confident that adhesive formulators and converters will find this new polymer offers extraordinary value not found with other polymer grades available in the marketplace today.”
