TSRC has announced the launch of Vector 4116N, a styrene-isoprene-styrene block copolymer polymer (SIS), which is tailor-made for label applications. It has a low styrene content and a mid-to high di-block SI/SIS ratio. TSRC said that the new product maintains the balance of initial tack and cohesion perfectly by offering high flow and creep resistance together with good wetting properties. In addition, it has very good die-cutting properties, making it suitable for a wide range of label applications.
The free-flowing, dense pellet form of the sister product Vector 4116ND is expected to improve storage, handling, and polymer feeding in comparison to the porous Vector 4116N pellets. Properties are all the same for porous and dense pellet forms. The products are available in commercial quantities. Potential market applications include pressure sensitive hot melt adhesives for hygiene, label and tape, food packaging, and film lamination.
