Cationic Polyelectrolyte Quaternary Ammonium Polymer for Paper Retention, Drainage and Dry Strength | Bluwat Chemicals
Cationic Polyelectrolyte for Paper Retention, Drainage and Dry Strength
Bluwat Chemicals — quaternary ammonium polymer solutions for modern papermaking
Overview
Bluwat Chemicals supplies PolyDADMAC, a quaternary ammonium polymer also referred to as a cationic polyelectrolyte, for wet end optimization in paper mills. It functions as a paper retention aid, paper drainage aid, and a dry strength additive. With strong cationic charge and multiple molecular weight grades, it stabilizes wet end chemistry, improves machine runnability, and enhances sheet properties across fine paper, packaging, and board.
Key Benefits in Papermaking
- Retention — captures fines and fillers, reducing white water load and improving formation.
- Drainage — accelerates dewatering on wire and press, lowering steam demand in dryers.
- Dry strength — improves tensile and internal bonding with low impact on optical properties.
- Compatible with starch, sizing agents, PAC, bentonite, silica sols for dual or microparticle programs.
- Broad pH operability supports seasonal furnish changes and closed white water loops.
