Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer developed to tackle pitch and stickies obstacles in pulp and paper manufacturing. After dissolution, extended PEO molecular chains adsorb and wrap hydrophobic resin particles and recycled sticky contaminants. It stabilizes micro impurities in slurry and prevents them from aggregating into large sticky deposits. This product effectively lowers contamination buildup on paper machine equipment, minimizes pap

Product Detail

Product Overview

Polyethylene Oxide PEO CAS 25322-68-3 serves as professional pitch and stickies control agent for pulp and paper enterprises. Mechanical pulp releases natural resin pitch; waste paper repulping generates micro stickies. These hydrophobic contaminants easily coalesce, adhere to forming fabrics, press felts and rollers, resulting in paper spots, pinholes and frequent web breaks. This PEO grade encapsulates pitch and sticky particles to maintain stable dispersion in pulp flow, reduce deposition risk, improve finished paper quality and extend fabric cleaning cycles.

Key Features

CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
Encapsulate pitch and micro stickies, suppress coalescence and sticky sediment formation
Reduce contaminant deposition on wire, press felt, calender and paper machine surfaces
Greatly lower paper faults including surface spots, pinholes and production web breaks
Nonionic structure, stable performance within wide pH range of papermaking wet end
Excellent compatibility with mechanical pulp, TMP and recycled waste paper pulp
Low dosage, will not negatively impact sheet formation, retention and drainage system
Convenient liquid preparation under low-shear gentle stirring

Main Applications

Stickies dispersing control agent for waste paper recycled pulp production lines
Natural pitch barrier additive for mechanical pulp and thermomechanical pulp (TMP)
Deposit control chemical for paper machines suffering resin and tacky contaminant troubles
Auxiliary wet-end additive for tissue, newsprint, packaging board made from recycled fiber

Usage Guidance

Gradually disperse PEO powder under mild continuous stirring to avoid agglomeration and fish-eye particles. Prepare dilute aqueous solution and add before pulp screening or headbox. Carry out factory on-site trials to confirm optimal dosing amount. Avoid prolonged high-shear stirring which breaks polymer molecular chains and weakens efficacy.

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
