SIS is a thermoplastic elastomer combining the elasticity of rubber with the processability of thermoplastics.
It is widely used in pressure-sensitive adhesives, hot-melt adhesives, tapes, labels, diapers, and packaging due to its excellent tack and flexibility.
SIS provides good low-temperature performance, cohesive strength, and compatibility with tackifying resins and oils.
It is not typically used as a direct pharmaceutical excipient but is important in medical tapes, plasters, and packaging materials.
