Premium grade gases, liquid rubber compounds, and metal powders engineered to match standard and custom specifications.
A deep look into the synthesis parameters, purity controls, and global supply dynamics of CAS No. 25322-68-3.
In modern industrial synthesis, chemical compounds with high molecular versatility serve as the foundation for manufacturing. Among these, Polyethylene Glycol (PEG), cataloged under CAS No. 25322-68-3, stands out as a critical polyether compound used in fields ranging from pharmaceutical formulation to polymer manufacturing. The stability, biocompatibility, and adjustable viscosity of PEG make it indispensable for processing modifiers, active pharmaceutical ingredients (APIs), thermal fluids, and polymeric binders.
As a leading supplier in China's specialty materials sector, YANXA (Yanxatech System Industries Limited) provides high-purity CAS No. 25322-68-3 configurations tailored for specific requirements. Our integration with certified research institutes in China guarantees consistent polymer distribution, low polydispersity indexes (PDI), and minimal catalyst residues, ensuring stability across industrial batches.
We supply a complete range of CAS No. 25322-68-3 products, matching standard grades from PEG 200 up to PEG 20000. Our advanced ethoxylation plants maintain trace-level limits on moisture, ethylene glycol monomers, and heavy metals, meeting international USP, EP, and industrial standards.

| Product Grade | Average Molecular Weight | Physical State (at 25°C) | Viscosity (mm²/s, 99°C) | Hydroxyl Value (mg KOH/g) | Primary Industrial Application |
|---|---|---|---|---|---|
| PEG 200 / 300 | 190 – 310 | Clear, colorless liquid | 4.0 – 5.8 | 340 – 590 | Organic synthesis intermediates, plasticizers for polymers, inks |
| PEG 400 / 600 | 380 – 620 | Viscous liquid | 6.8 – 11.5 | 178 – 295 | Solubilizers, cosmetic formulations, liquid rubber processing aids |
| PEG 1000 / 1500 | 950 – 1550 | Soft waxy solid | 22 – 36 | 70 – 118 | Water-soluble lubricants, binder systems for powder metallurgy |
| PEG 4000 / 6000 | 3600 – 7000 | White flakes or powder | 110 – 470 | 16 – 31 | Tablet binders, mold release agents, specialized coating formulas |
| PEG 8000 / 20000 | 7000 – 22000 | White crystalline powder | 470 – 9000 | 5 – 15 | Paper coatings, water-soluble packaging films, thickening agents |
Our manufacturing sites utilize automated loop reactor technologies for ethoxylation, ensuring narrow molecular weight distribution (MWD) curves. Reducing high-MW tails improves dissolution speed and process consistency for downstream formulations.
For applications sensitive to trace compounds, our refining stages drop free ethylene oxide (EO) and 1,4-dioxane levels below 1 ppm and 10 ppm respectively. This matches USP guidelines, qualifying our product for cosmetic and biotech use.
From acting as soft segments in polyurethane elastomers to providing wetting properties in atomized alloy powders, PEG's chemical versatility makes it a core component for advanced material designs.

Deep engineering insights into manufacturing methodologies, industrial workflows, and application optimization.
Polyethylene glycol is synthesized by the anionic polymerization of ethylene oxide initiated by water, monoethylene glycol, or diethylene glycol. The catalytic system, typically sodium or potassium hydroxide, is carefully neutralized and filtered out to prevent downstream decomposition or catalytic activity in polymer formulations.
For liquid rubber systems (such as CTBN or ATBN), higher-grade PEG forms serve as structural chain extenders and processing aids. They balance raw viscosity while helping distribute filler materials like silica and carbon black within the elastomer matrix, improving mechanical properties.
During the compaction of atomized alloy powders (such as Flake Zn-Al or Al-Mg systems), PEG 4000 and 6000 act as high-performance binders and lubricants. They clean burn-out completely during sintering without leaving carbon deposits that degrade metal grains.

Procuring raw materials like CAS No. 25322-68-3 (PEG), reactive monomers, or combustible powders requires specialized supply chain systems. Chemical logistics must comply with strict national regulations in China and international destination ports. YANXA addresses these challenges through integrated safety systems, real-time logistics monitoring, and compliance documentation.
We work with established logistics providers to handle transport classifications for hazardous and non-hazardous products. Solid PEG forms are stored in temperature-controlled warehouses to prevent clumping during seasonal transits. Gases like Argon and Neon are shipped in high-pressure cylinders with complete DOT, ISO, or TPED certifications.
In addition, our manufacturing facilities adhere to strict EHS (Environment, Health, Safety) parameters. This ensures production stability, avoiding sudden environmental shutdowns and guaranteeing stable contract pricing for our global partners.
