PULPSIL® 270 C

1 of 18 products in this brand
PULPSIL® 270 C is a highly viscous, relatively alkaline-resistant, extremely efficient, solvent- and water-free silicone antifoam compound, specially developed for use in pulp mills. It is particularly effective when formulated as an emulsion, making it an excellent antifoam agent for various pulp processing steps, including washing, screening, bleaching, and wastewater treatment. The product exhibits thixotropic properties, requiring gentle stirring to reduce viscosity.

Application Details
  • For high efficiency it is necessary that PULPSIL 270 C be well dispersed in the foaming medium. Therefore PULPSIL 270 C can be added only in neat form if high amounts of surfactants and/or high shear forces ensure a good dispersion. Preferably PULPSIL® 270 C should be added in emulsion form.
  • The use as a booster to organic defoamers is also possible, but sufficient compatibility of PULPSIL® 270 C with the organic system has to be guaranteed.
  • When used in suitable formulation like emulsion, PULPSIL® 270 C is an excellent antifoam agent, recommended for the use in the different pulp processing steps like washing, screening, bleaching and waste water treatment. The product is thixotropic. Weak stirring is necessary to reduce the viscosity.
