SIS (Styrene-Isoprene-Styrene)

Product Overview

SIS (Styrene-Isoprene-Styrene block copolymer) is a thermoplastic elastomer polymerized with styrene and isoprene as main monomers. It offers excellent elasticity, adhesion properties, and processing characteristics. Product characteristics include good storage stability, high hardness, good toughness, high non-slip effect, and wear resistance. SIS is widely used in various applications including asphalt modification, hot-melt pressure-sensitive adhesives, product modification for daily necessities, stationery, toys, automotive interior decoration, food packaging, and applications in electrical insulation, diapers, sanitary napkins, labels, and medical products.
