SBS and SEBS Adhesives Technologies
Styrene Block Copolymers (SBC) are synthetic polymers that have versatile properties due to their molecular structure, which is an aromatic-aliphatic combination. Styrene-ethylene-butadiene-styrene (SEBS) and styrene-butadiene-styrene (SBS) are two types of SBCs that are used in adhesives and sealants. SEBS are saturated triblock polymers that are made by hydrogenating SBS during the manufacturing process. SEBS have a higher tensile strength and service temperature than unsaturated SBS, and SEBS are less vulnerable to thermal and ultraviolet light degradation.
SBS and SEBS Adhesives Market Drivers
SBC markets have undergone several changes in recent years, including commoditization of SBCs, emergence of new SBC producers, capacity additions, and developments of alternate competing polyolefins and elastomers. Polymer modification is the largest use of SBCs but there are several other important application areas, including adhesives and sealants. Adhesives are used, for example, in pressure-sensitive formulations, tapes, hot-melts, contact, and spray adhesives. SBC adhesives compete with alternate technologies. For example, in nonwoven markets, SBC use is declining as manufacturers switch away from SBCs that have a scent to non-fragrant acrylics. SBS-based adhesives can be used by itself or in combination with another SBC copolymer, in applications such as diapers, packaging, automotive, and construction. SEBS-based sealants are used in variety of applications including tapes, labels, coatings, and road-making paints. The figure below shows growth of SEBS in a range of applications. Exhibit 1 shows global SEBS demand by application.
