3.1 SIS Elastomer
SIS elastomer is styrene-isoprene-styrene block copolymer, which is a new type of thermoplastic elastomer. These SIS copolymers provide increased adhesion and flexibility to adhesive applications such as tapes and labels while offering soft stretch, a comfortable feel, and an excellent fit to elastic attachment adhesives in hygiene products such as diapers. Because of many excellent properties such as thermoplasticity, high elasticity, low melt index and solution viscosity and good compatibility with tackifying resins, SIS elastomers are widely used in adhesives, coatings, plastic and asphalt modification. They can be used to make sanitary towels, paper diapers, double-sided adhesives, labels, etc.

3.2 SBS Elastomer
SBS elastomer is styrene-butadiene-styrene block copolymer, possessing the advantages of both rubber and plastic with excellent low temperature endurance,air permeability and wet-skid resistance.The SBS is characterized by easy molding and coloring, none vulcanization and simple processing,low energy consumption.The leftover bits and pieces can be recovered.SBS elastomers are widely used in footwear,adhesives,waterproof coiled materials,modification of polymers and road asphalt,cable,toys,etc.
