• Construction Gypsum-board, Plasterboard and Drywall Flow and Dispersing Agent

PNS (Poly Naphthalene Sulfonate)

• Overall, PNS plays a vital role in the manufacturing process of gypsum board, helping to improve the flow properties, workability, and quality of the final product. It is available in various forms and grades and can be tailored to meet the specific requirements of the production process.

  PNS (Poly Naphthalene sulfonate) is a commonly used water-reducing, flow, and dispersant additive in the manufacturing process of gypsum board (aka plasterboard and drywall).

  • As a water-reducing additive, PNS reduces the amount of water needed in the mixture to achieve the desired level of workability. This helps increase the final product’s strength and minimize the risk of shrinkage or cracking.
  • As a flow additive, PNS acts by improving the fluidity of the mixture and allowing it to be poured or pumped quickly and evenly. This results in a more uniform and consistent product with fewer defects or inconsistencies.
  • As a dispersant additive, PNS helps to create a stable and uniform dispersion of particles within the mixture, reducing clumping and promoting even distribution. This is particularly important in the case of gypsum boards, where uneven distribution can result in weak spots or inconsistent quality.
