Selvol Range

In addition to Sekisui Specialty Chemicals’s standard product line, several specialty grades are available, including polymerisation, fine particle size and tackified polyvinyl alcohols. Selvol[TM] Polyvinyl Alcohols 805, 823 and 840 are improved versions of standard polymerisation grades (Selvol[TM] Polyvinyl Alcohol 205, 523 and 540 polyvinyl alcohols, respectively). These products offer a number of advantages in emulsion polymerisation applications including improved water solubility and lower foaming. Selvol[TM] Polyvinyl Alcohol S-grades are similar to standard grades, but have a fine particle size so that 99+% of the product will pass through a USS 80-mesh screen. These grades are available commercially as Selvol[TM] Polyvinyl Alcohol 203S, 205S, 523S and 540S polyvinyl alcohols. Tackified Selvol[TM] Polyvinyl Alcohols are produced by controlled boration of super hydrolysed and fully hydrolysed grades. These borated alcohols yield viscous aqueous solutions, which have a tailored degree of tack and significantly reduce penetration when applied onto surfaces such as paper.
