Solprene 1205 Random-block styrene-butadiene copolymer Dynasol Styrene block copolymer (SBC) >> Styrene butadiene styrene rubber, SBS ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Hot-melt SEALANT Solprene 1205 is a linear random-block styrene-butadiene copolymer having 25% of styrene content, 17.5% present as a polystyrene block 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-1205 is an excellent modifier for asphalt, for formulation of caulks and sealants, it is also an excellent processing aid for most polymers, giving good low temperature resistance. Used in extruded goods, soles, and heels. It can also be used as modifier for thermoplastic resins and in adhesive formulations. 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. Hot melt adhesives Excellent tack Low molecular weight special grade, used in formulations with natural rubber, SIS Linear random-block styrene-butadiene copolymer. Possesses a non staining antioxidant system. Used for formulation of caulks and sealants and as a processing aid for most polymers. Gives good low temperature resistance. Can be used as a modifier for thermoplastic resins and in adhesive applications. Offers adhesion to cloth, paper, films and sheet metal for PSA. Provides high tack in hot melt adhesives. Applications: pressure sensitive adhesives (masking tape, cellophane tape, insulating tape, tapes for sealing and binding, decorative contact paper and labels) and hot melt adhesives.
