PULPSIL® 968 S
PULPSIL® 968 S is a water dispersible, hydrolyticly stable silicone surfactant based on a polyethermodified silicone fluid.
PULPSIL® 968 S was developed for application in pulp and paper industry.
PULPSIL® 968 S:
- enhances the effiency of paper deaerators at a dosage of 1.0 - 10.0 % referred to solid material of deaerator.
- improves the drainage / deaerating in the pulp process at following dosage levels:
hardwood: 8 to 50 ppm referred to fibres
softwood: 8 to 100 ppm referred to fibres
- works itself as a booster for pulp-defoamers above its cloud point at a dosage of 2.0 - 20 % referred to active material of defoamer.
The best dispersibility PULPSIL® 968 S in water can be achieved by using high shear forces (e.g. turrax or dissolver). At low shear forces (e.g. stirrer) we recommend to start with water and then to add PULPSIL® 968 S while stirring continously. Stir the mixture for at least 1 hour. The aqueous mixture separates after a few days. We therefore recommend temporary stirring at a high shear force (3 times a day for 20 minutes at 500 rpm).
Storage
Store in a dry and cool place.
The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
