MOSCOW (MRC) -- Munich-based chemicals group Wacker has developed a new silicone surfactant that greatly accelerates pulp dewatering, as per the company's press release.
Sold under the name PULPSIL 968 S, it serves as the active ingredient for dewatering formulations used in pulp washing. The silicone delivers unparalleled efficiency in pulp dewatering and slashes the washing time. PULPSIL 968 S rounds out the existing Wacker range of products for Pulp & Paper, and can generate substantial energy and cost savings for pulp producers.
The rate at which pulp slurry is dewatered can be measured in drainage tests. Wacker’s new silicone tensid PULPSIL 968 S accelerates dewatering to unprecedented levels and improves the washing process during pulp making significantly.
PULPSIL 968 S, a medium-viscosity water-dispersible product, is a surfactant fluid based on a polyether-modified silicone. Its molecular structure has been optimized to make it less hydrophilic without compromising its pronounced hydrophobic or water-repellent properties. The resultant gain in water repellency, compared with other silicone surfactants, is what makes PULPSIL 968 S such a particularly efficient dewatering agent.
PULPSIL 968 S is designed to serve as a raw material for service companies that develop ready-to-use auxiliaries for the pulp industry. With this new silicone surfactant, formulations can be tailored to the process of any given pulp mill. Like the dewatering agents PULPSIL 955 S and PULPSIL 960 S, PULPSIL 968 S is generally used in combination with a silicone defoamer.
As MRC informed before, Wacker Chemie said will increase its 2014 dividend to EUR1.50 (USD1.59) from EUR0.50 following a marked increase in sales and earnings, but full-year net profit is expected to fall below the 2014 figure due to lower special income and a tax rate of slightly more than 50%.
Wacker Chemie AG is a worldwide operating company in the chemical business, founded 1914. The company is controlled by the Wacker-family holding more than 50 percent of the shares. The corporation is operating more than 25 production sites in Europe, Asia, and the Americas. The product range includes silicone rubbers, polymer products like ethylene vinyl acetate redispersible polymer powder, chemical materials, polysilicon and wafers for semiconductor industry.
