Styrene-Isoprene-Styrene (SIS)

Block copolymer for pressure-sensitive and hot-melt adhesives — tapes, labels and hygiene.

Styrene-isoprene-styrene (SIS) is a thermoplastic block copolymer that combines rubbery flexibility with thermoplastic processability. It is the preferred polymer for pressure-sensitive and hot-melt adhesives, delivering excellent tack, flexibility and quick bonding.

Aleemsons supplies SIS for the adhesive industry — tapes, labels, hygiene products and assembly hot-melts — alongside the tackifier resins and waxes that complete the formulation.
