Polyethylene Oxide MW 2,000,000 CAS 25322-68-3 Ultra High Viscosity Polymer for Paper Making
Polyethylene Oxide MW 2,000,000 (PEO 2M, CAS 25322-68-3) is linear ultra-high molecular weight water-soluble polyether polymer. Used in papermaking wet-end process, it produces powerful bridging flocculation on fine cellulose fibers, inorganic fillers and tiny impurities. It enhances retention rate of fines, accelerates dewatering on wire section, improves paper formation and reduces fiber loss in white water. It has good compatibility with various papermaking chemicals, serving as eco-friendly
Product Overview
Polyethylene Oxide MW 2,000,000 (CAS 25322-68-3) is ultra-high molecular weight PEO specially developed for papermaking wet-end treatment. Medium molecular weight PEO lacks sufficient flocculation capacity for micro-fibers; excessively high molecular weight polymer tends to cause over-flocculation and uneven paper formation. This 2M grade achieves balanced flocculation effect and solution rheology. After dissolving in white water, long polymer chains adsorb on fiber surfaces and connect fine particles into loose micro flocs. It promotes sheet dewatering, reduces vacuum load of paper machine, lowers raw material consumption and improves surface smoothness of finished paper.
Key Features
- Molecular Weight: 2,000,000, CAS 25322-68-3, white free-flowing fine powder
- Excellent water solubility, can be prepared into low-concentration working solution
- Outstanding bridging flocculation performance for fine fiber and mineral fillers
- Improve retention rate of fines, reduce fiber and filler loss in white water
- Accelerate drainage on forming section, lower energy consumption of paper machine
- Optimize paper formation, enhance uniformity and surface quality
- Nonionic characteristic, stable performance under wide pH pulp environment
- Good compatibility with cationic starch, aluminum sulfate and other wet-end additives
Main Applications
- Retention and drainage aid for tissue paper, cultural paper and packaging paper
- Flocculating polymer for wet-end system of recycled pulp papermaking
- Formation improver for special industrial filter paper
- Auxiliary additive to reduce white water COD in paper mill circulating water system
Usage Guidance
Slowly disperse PEO powder into continuously stirred clean water to avoid agglomeration, prepare 0.05% dilute solution. Add evenly before pulp inlet of headbox. Typical dosage: 50~250 g per ton absolute dry pulp. Adjust dosage according to pulp type, beating degree and target paper quality. Complete lab retention test before machine trial.
Storage & Package
Seal packages tightly. Store in cool, dry and ventilated warehouse, avoid moisture absorption and direct sunlight. Standard package: 25kg kraft paper bag with inner PE liner. Shelf life: 12 months under proper storage.
Service Support
Test samples available for paper machine trial. Stable bulk supply. We provide technical support for papermaking wet-end formulation. Welcome to inquire TDS, COA and factory quotation.
