PULPSIL 968 S is a high-performance functional silicone fluid in Wacker’s PULPSIL series, a high-efficiency silicone defoamer designed for the entire pulp production process. It has excellent defoaming, foam-suppressing performance and process compatibility, quickly eliminating foam in pulp production, optimizing pulping processes, reducing energy and chemical consumption, and improving pulp 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
