Effect of Diblock Addition on HMA/PSA Performance, 1996 Hot Melt Symposium Proceedings

A correlation between hot melt adhesive (HMA) and pressure sensitive adhesive (PSA) performance and the addition of styrene-butadiene diblock to styrene-butadiene-styrene thermoplastic elastomers (TPEs) was developed. Included in this study was the examination of microstructure variation of both the diblock and TPE structures and its effects on ultimate adhesive performance. Manipulations of the quantity of diblock, microstructure, and macrostructure were made. Additionally, the effect of separate changes in the microstructure of the diblock and the TPE were identified. Performance properties of the completed adhesive were measured using specific control formulations. Some of the adhesive tests included the following: tack performance to inert substrates, cohesive tensile, viscosity, shear adhesion failure, and dynamic shear analysis.
