Understanding Ethylene Glycol Diacetate Properties
Ethylene glycol diacetate (C6H10O4) combines the solvent characteristics of both esters and glycols, making it unique among chemical intermediates. With a boiling point of 190-191°C and freezing point of -40°C, this clear liquid serves as a high-performance coalescing agent and plasticizer. The compound's low acute toxicity profile (LD50 Oral Rat: 6,860 mg/kg) distinguishes it from more hazardous alternatives, while its dielectric constant of 11.2 enables specialized applications in electronics manufacturing. Material compatibility extends to polyvinyl acetate, nitrocellulose, and cellulose acetate butyrate systems.
Technical Specifications and Material Performance Data
Premium-grade ethylene glycol diacetate
exceeds industry purity thresholds with ≥99.0% assay (GC) and water content below 0.05%. These specifications ensure batch-to-batch consistency critical for production processes. Performance benchmarking demonstrates significant advantages: a 40% improvement in coating adhesion strength versus propylene-based solvents and evaporation rate 1.7 times faster than butyl glycol acetate. The table below details key technical parameters:
| Parameter | Test Standard | Typical Value |
|---|---|---|
| Density at 20°C | ASTM D4052 | 1.106 g/cm³ |
| Vapor Pressure at 25°C | ASTM D5191 | 0.17 kPa |
| Flash Point | ISO 3679 | 101°C |
| Viscosity at 25°C | ASTM D445 | 3.2 mPa·s |
Industrial Advantages Over Competing Solvents
Manufacturing operations report 15-20% cost reduction when substituting ethyl lactate with ethylene glycol diacetate due to superior solvency power. The compound delivers critical formulation advantages through simultaneous hydrophobic and hydrophilic interactions. This amphiphilic nature allows dissolution of both natural resins and synthetic polymers where acetone-diethyl ether mixtures fail. Additionally, its slow evaporation profile enables optimal film formation without bubble entrapment during curing cycles.
Supplier Comparison Metrics and Certification Analysis
Global suppliers demonstrate significant variance in ethylene glycol diacetate production capabilities. ISO 9001 certification shows compliance with international manufacturing standards, but only 30% meet REACH Annex XVII requirements for consistent low-metal profiles. Comparative analysis reveals Tier-1 producers achieve tighter boiling range control (189°C-192°C) versus secondary suppliers operating at 185°C-195°C ranges. Packaging innovation includes nitrogen-purged drums for oxidation-sensitive applications. Key supplier benchmarks:
| Manufacturer | Purity Grade | ISO Certifications | Lead Time |
|---|---|---|---|
| Supplier A | 99.9% | 9001/14001 | 4 weeks |
| Supplier B | 99.2% | 9001 | 8 weeks |
| Supplier C | 98.7% | N/A | 2 weeks |
Customized Formulation Options
Specialty applications require tailored ethylene glycol diacetate compositions. Customized solutions include molecularly distilled fractions for optical film manufacturing and low-acidity grades (<20 ppm acetic acid) for electronics cleaning. Co-solvent blends incorporating 10-15% ethyl acetate enhance solvency power for epoxy adhesives without VOC penalties. Suppliers offering on-site technical support report 90% success rates in formulating application-specific blends compared to standard bulk supply.
Documented Application Performance in Key Industries
Printing ink formulations with ethylene glycol diacetate demonstrated 25% faster drying rates versus glycol ether alternatives during rotary press trials. In paint strippers, user safety significantly improved with workplace airborne concentrations measuring below 5 ppm versus 28 ppm for dimethylformamide solutions. Additionally, cable manufacturers achieved 15% plasticization efficiency gains in PVC compounds compared to traditional phthalate systems.
