Solprene 4580X Thermoplastic butadiene and styrene copolymer Dynasol Styrene block copolymer (SBC) >> Styrene butadiene styrene rubber, SBS ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) Solprene 4580X is a linear multiblock copolymer of styrene and butadiene with high vinyl (>25%), having 45% of styrene content, most of this one appears like block polystyrene, which gives the polymer a thermoplastic behavior. It has a non staining antioxidant system FDA approved for use in food contact applications and is essentially gel free with a very clear color. S-4580X is used in formulations of adhesive and like modifier of impact for plastics. These adhesives are used in products such as masking tape, cellophane tape, insulating tape, tapes for sealing and binding, decorative contact paper and labels. Some recent applications are used for installing tiles and other heavy objects. Pressure-sensitive adhesives may be used on cloth, paper, films and sheet metal. The latter two are normally covered with a thin layer of fixative to improve the bonding of the adhesive. Formulations which only use natural rubber tend to soften over time, while those using SBRs become hard as a result of oxidization. Linear thermoplastic multiblock copolymer of styrene and butadiene with high vinyl content. Used in adhesives. Offers adhesion to cloth, paper, films and sheet metal for PSA. Applications: pressure sensitive adhesives (masking tape, cellophane tape, insulating tape, tapes for sealing and binding, decorative contact paper and labels).
