Fundamental Properties of CAS: 9002-89-5 in Polymer Chemistry

Polyethylene glycol (PEG) derivatives classified under CAS: 9002-89-5 represent foundational materials in modern industrial chemistry. These non-ionic surfactants exhibit hydrophilic-lipophilic balance values ranging from 8-18, enabling diverse functionality across formulation chemistry. Molecular weights typically span 200-10,000 g/mol, providing distinct solution viscosities between 20-500 cP at 25°C.

Industrial utilization extends beyond basic surface activity due to the amphiphilic character of these compounds. Approximately 78% of pharmaceutical formulations incorporate these polymers as solubilizers, while 63% of agrochemical preparations utilize their emulsification capabilities. Regulatory compliance status includes FDA 21CFR175.105 approval for indirect food additives and REACH Annex VII registration.

Technical Advantages Across Polymer Categories

Specialty polymers identified by CAS: 9004-32-4 (polyvinyl acetate) and CAS: 9049-76-7 (polyvinyl butyral) demonstrate complementary characteristics to polyethylene derivatives. Polyvinyl acetate emulsions exhibit tensile strengths exceeding 40 MPa with adhesive bond strengths measuring 3.5-4.5 N/mm² across substrate interfaces. These polymers display glass transition temperatures (Tg) ranging from 28-31°C, enabling flexible film formation.

Critical performance differentials emerge when examining hydrolytic stability parameters. While polyethylene glycols maintain 97% structural integrity after 100-hour accelerated aging tests at 60°C, polyvinyl acetates show superior moisture barrier properties with water vapor transmission rates below 10 g/m²/day. Thermal decomposition profiles reveal polyethylene glycol stability up to 250°C versus polyvinyl butyral's limited 200°C threshold.
