Polyethylene Oxide MW 300,000 (PEO 300k, CAS 25322-68-3) is linear nonionic polyether polymer powder. Its medium molecular weight provides proper solution viscosity and excellent bridging flocculation performance. When added to pulp slurry, it aggregates tiny fibers and inorganic fillers, reducing material loss in white water, accelerating web dewatering and enhancing paper uniformity. It is eco-friendly functional auxiliary for various papermaking systems.

Product Detail

Product Overview

Polyethylene Oxide MW 300,000 (CAS 25322-68-3) is specially developed medium molecular weight PEO for papermaking industry. Low molecular weight PEO shows insufficient flocculation capacity, while ultra-high molecular weight grades easily cause excessive floc and uneven paper formation. This 300k grade achieves balanced retention effect and floc size control. It forms polymer bridges between pulp particles, intercepting fine fibers and fillers on wire section. It helps enterprises reduce raw material consumption, increase machine speed and relieve wastewater treatment pressure.

Key Features

Molecular Weight: 300,000, CAS 25322-68-3, white free-flowing powder
Medium solution viscosity, outstanding bridging flocculation property
Great retention performance for fine fiber, talc, calcium carbonate fillers
Improve wire drainage efficiency, increase paper machine operating speed
Reduce solid content of white water, lower raw material waste
Nonionic property, stable performance over wide pH range of pulp slurry
Good compatibility with other papermaking wet-end additives

Main Applications

Retention and drainage aid for tissue paper, toilet paper production
Retention auxiliary for kraft packaging paper, liner board and corrugated paper
Functional polymer for cultural paper and coated base paper wet end system
Flocculating additive for pulp recycling process

Usage Guidance

Slowly scatter PEO powder into continuously stirred water to prevent agglomeration, prepare 0.05%~0.2% dilute solution. Add the aqueous solution before pulp enters the headbox. Recommended dosage: 50~300ppm based on absolute dry pulp weight. Adjust dosage according to pulp type, filler dosage and target retention rate. Complete on-machine small trial before large-scale application.

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 mill trial. Stable bulk supply. We provide technical guidance for papermaking wet-end formulation. Welcome to inquire TDS, COA and factory quotation.
