Polyethylene Glycol PEG8000 J6502 Enhance paper gloss and smoothness Serve as an additive in the rubber industry
Chinese Name: Polyethylene glycol
English Name: Polyethylene glycol
CAS No.: 25322-68-3
Molecular Formula: (CH₂CH₂O)_n
Polyethylene glycol exhibits varying properties depending on its relative molecular mass, ranging from colorless, odorless viscous liquids to waxy solids. Those with molecular weights between 200 and 600 are liquid at room temperature, while those above 600 gradually become semi-solid. Properties also differ with changes in average molecular weight. From colorless, odorless

I. Product Overview:
Chinese Name: Polyethylene glycol
English Name: Polyethylene glycol
CAS No.: 25322-68-3
Molecular Formula: (CH₂CH₂O)_n
Polyethylene glycol exhibits varying properties depending on its relative molecular mass, ranging from colorless, odorless viscous liquids to waxy solids. Those with molecular weights between 200 and 600 are liquid at room temperature, while those above 600 gradually become semi-solid. Properties also differ with changes in average molecular weight. From colorless, odorless viscous liquids to waxy solids. As molecular weight increases, hygroscopicity correspondingly decreases. Soluble in water, ethanol, and many other organic solvents. Low vapor pressure; stable to heat, acids, and alkalis. Reacts with few chemicals. Exhibits excellent hygroscopicity, lubricity, and adhesive properties. Non-toxic and non-irritating.

III. Applications:
PEG-8000 serves as an excipient in pharmaceutical manufacturing for suppository and ointment preparation; functions as a coating agent in papermaking to enhance paper gloss and smoothness; acts as an additive in rubber processing to improve lubricity and plasticity of rubber products, reduce energy consumption during manufacturing, and extend product lifespan.
In pharmaceutical and cosmetic manufacturing, it serves as a matrix to regulate viscosity and melting point; in rubber and metal processing, it functions as a lubricant and coolant; in pesticide and pigment production, it acts as a dispersant and emulsifier; in textiles, it is used as an antistatic agent and lubricant.
