PolyDADMAC for Paper-Making: Retention Aid, Drainage Aid and Dry Strength Enhancer | Bluwat Chemicals
PolyDADMAC for Papermaking: Retention Aid, Drainage Aid, Dry Strength Enhancer
Bluwat Chemicals — specialty polymers for wet end optimization and paper machine efficiency
Overview
Bluwat Chemicals supplies PolyDADMAC for the paper-making industry to improve fines and filler retention, accelerate drainage, and enhance dry strength. With high cationic charge and multiple molecular weight options, PolyDADMAC stabilizes wet end chemistry, supports white water closure, and helps mills achieve better runnability and sheet quality.
Why PolyDADMAC in Paper-Making
- Retention aid: increases fines and filler capture, improving sheet formation and reducing losses to white water.
- Drainage aid: speeds water removal on the wire section and short press, lowering steam demand in dryers.
- Dry strength: boosts tensile and internal bond strength without affecting brightness.
- Compatible with sizing agents, starch, and common inorganic coagulants in dual-polymer or microparticle programs.
- Wide pH operability ensures stable performance across furnishes and seasonal shifts.
