PULPSIL® 255 C

1 of 18 products in this brand
PULPSIL® 255 C is a highly viscous, solvent-free, and water-free silicone antifoam compound specifically designed for use in pulp mills. It offers excellent efficiency in controlling foam. To achieve high efficiency, it is important to ensure proper dispersion of PULPSIL® 255 C in the foaming medium. This can be achieved by adding the product in its neat form, particularly when high amounts of surfactants and/or high shear forces are present to facilitate good dispersion.

Application Details
  • For high efficiency it is necessary that PULPSIL® 255 C be well dispersed in the foaming medium. Therefore PULPSIL® 255 C can be added only in neat form if high amounts of surfactants and/or high shear forces ensure a good dispersion. Preferably PULPSIL® 255 C should be added in emulsion form.
  • The use as a booster to organic defoamers is also possible, but sufficient compatibility of PULPSIL® 255 C with the organic system has to be guaranteed.
  • When used in a suitable formulation like an emulsion, PULPSIL® 255 C is an excellent antifoam agent, especially recommended for the use in different pulp processing steps like washing, screening, bleaching and waste water treatment. The product is thixotropic. Weak stirring is necessary to reduce the viscosity.
