Rodys LP is a surfactant being the sodium salt of polycondensates of naphthalene sulfonic acid with formaldehyde. It is offered in the form of light-brown powder, and is characterized by very low water content and low bulk density. The second feature translates into cost savings of transport and storage of the product. It is the equivalent of Rodys L in chemical and application terms.
The technology of Rodys LP production allows obtaining a product that neither has an environmental classification, nor does it affect the content of free aromatic hydrocarbons in the products for which it is used.
Rodys LP is a polymeric dispersant compound made of an organic chain with hydrophobic and hydrophilic sulfone groups. Due to this structure, it is adsorbed on the surface of particles, forming a layer of unipolar electrical charges. Their mutual repulsion causes the disintegration of agglomerates and the formation of dispersed systems, as well as non-coagulating suspensions of solids in a continuous liquid phase (water). Rodys LP enables the formation of time-stable dispersion, inhibiting the re-aggregation of particles.
With its unique properties, Rodys LP is widely used in various industries, in particular in the creation of wax dispersions with the desired physicochemical properties (viscosity, stability over time, dispersed particle size).
Due to the complexity of the dispersion process, as well as the multitude of key parameters, it is recommended to test the product in conditions as close as possible to those prevailing in the given application.
