PULPSIL 960 S is a high-performance polyether-modified functional silicone fluid in Wacker’s PULPSIL series, a hydrolytically stable silicone surfactant designed for pulp and paper industry. It features excellent water dispersibility and process compatibility, efficiently improving pulp dewatering, washing and defoaming, while enhancing pulp uniformity and quality.
Hydrolytically stable and alkali-resistant - Stable performance in high-temperature and high-alkali conditions, suitable for harsh pulp production environments
Efficient water dispersibility - Easily soluble in aqueous systems, no additional emulsification required, easy to add
Enhanced dewatering efficiency - Accelerates pulp filtration and dewatering, shortens process cycle and reduces energy consumption
Auxiliary defoaming and foam suppression - Synergizes with defoamers to improve foam control and reduce production fluctuations
Improve pulp quality - Improves fiber dispersion and uniformity, reduces paper defects and optimizes paper forming performance
Pulp washing - Optimizes washing effect, reduces washing water consumption, and improves washing efficiency
Screening and classification - Eliminates foam in screening, prevents screen clogging, and improves screening efficiency and accuracy
Bleaching process - Suitable for various bleaching baths, avoids foam affecting bleaching uniformity, and reduces bleach loss
Wastewater treatment - Treats pulp production wastewater, eliminates wastewater foam, and optimizes wastewater treatment process
Pulp modification - Assists in improving pulp fluidity, reduces process hidden dangers in production, and ensures production continuity
