Modified POSITEK™ Microparticle
High-Performance Modified Silica for Reliable Productivity Across pH Ranges
The wet end is one of the most complex and critical areas in the papermaking process. Poor drainage here can throttle machine productivity, leading to slower speeds, compromised sheet quality, and higher energy costs in the drying section. Modified POSITEK Microparticle is engineered to overcome these bottlenecks, delivering measurable gains in productivity without sacrificing quality.
Modified POSITEK Microparticle is a high-activity, modified silica solution designed to perform across a wide pH spectrum, including acid, neutral, and alkaline systems. Its robust performance in high-conductivity environments makes it ideal for mills seeking to optimize retention, drainage, and formation under challenging conditions.
Key Benefits
- Faster Machine Speeds: Enhances forming section dewatering for improved throughput
- Improved Retention: Captures fines, fillers, and additives more efficiently
- Lower Steam Demand: Reduces drying energy needs through better water removal
- Broad pH Compatibility: Effective in acid, neutral, and alkaline papermaking systems
- High-Conductivity Resilience: Maintains performance even in closed-loop or high-salt environments
- Higher Actives: Delivers more impact per dose compared to conventional modified microparticles
Sustainable by Design
Modified POSITEK Microparticle supports your sustainability goals by reducing water and energy use, and enabling the use of lower-grade fiber—all while maintaining high-quality output.
