Zheng Bang’s Auxiliary Dispersant is a water-soluble modified polyvinyl alcohol (PVA) solution used as an auxiliary dispersant in the suspension polymerization of vinyl chloride. Often used in the production of suspension PVC (sPVC) resin, it works in conjunction with a primary dispersant to improve the quality, properties and performance of the final sPVC resin. Porosity is high, improving monomer removal and plasticizer absorption, plasticization time is shorter and the number of fish eyes is reduced. In comparison to other auxiliary dispersants, the apparent density of the PVC is improved.
