Polyethylene Oxide CAS 25322-68-3 Retention and Drainage Aid for Paper Machine
Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer designed for paper mill wet-end application. After dissolving in white water, extended polymer chains produce bridging flocculation to gather fine cellulose fibers, mineral fillers and tiny fines. It significantly enhances first-pass retention, promotes dewatering on forming wire, lowers white water load and facilitates wastewater recycling. This polymer works steadily under neutral and alkaline papermaki
Product Overview
Polyethylene Oxide CAS 25322-68-3 is professional wet-end retention and drainage aid for paper machines. Conventional ionic retention aids are easily disturbed by anionic trash in pulp. This PEO nonionic polymer achieves good flocculation effect without being severely affected by charge fluctuation. It optimizes drainage performance, improves production efficiency and cuts consumption of other papermaking chemicals.
Key Features
- CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
- Excellent bridging flocculation effect for fine fibers and inorganic fillers
- Improve first-pass retention, reduce loss of raw materials in white water
- Accelerate wire section drainage, allow higher paper machine running speed
- Nonionic property, less susceptible to pulp anionic impurities
- Stable performance under neutral and alkaline papermaking environment
- Improve formation uniformity without causing oversized flocs and paper spots
- Low dosage, effectively reduce overall papermaking chemical costs
Main Applications
- Retention and drainage additive for tissue paper, kraft paper and paperboard production
- Wet end functional chemical for specialty paper manufacturing lines
- Auxiliary retention agent for mechanical pulp and chemical mixed pulp
- Pulp treatment additive for paper mills with white water recycling system
Usage Guidance
Slowly disperse PEO powder under gentle continuous stirring to avoid agglomeration and fish-eye particles. Prepare dilute aqueous solution and add before headbox. Conduct lab dynamic retention and drainage tests to confirm optimal dosage. Avoid prolonged high-shear stirring which breaks molecular chains and weakens performance.
Storage & Package
Seal packages tightly. Store in cool, dry and ventilated warehouse. Prevent moisture absorption, high temperature and direct sunlight. Standard package: 25kg kraft bag with inner PE liner. Shelf life: 12 months under properly sealed storage.
Service Support
Test samples available for papermaking laboratory evaluation. Stable bulk supply. We provide TDS, COA and wet-end application technical guidance. Welcome to inquire factory quotation.
