Applicable Type

Hot-melt Adhesives

Applicable Base Polymer

Styrene Block Copolymers, SBC (SBS, SEBS, SEPS, SIS)

Applicable Industrial Sectors

Buildings & constructions , Industrial Assembly , Labels / Signs / Decals , Tapes

Applicable Base Polymer Properties

Styrene block copolymers (SBCs) offer cohesion, strength, and heat resistance for both pressures sensitive adhesives (PSAs) and non-pressure sensitive adhesives. The styrene phase forms a physically crosslinked network in the adhesive at room temperature. Of the SBCs, styrene butadiene styrene has the highest shear strength and moderately good peel strength.
