What is Polyethylene adipate?
Polyethylene adipate (CAS 24938-37-2) is a polyester polyol produced by condensing ethylene glycol with adipic acid.
Where is Polyethylene adipate used?
- Polyurethane manufacturing: polyol building block for flexible foams and elastomers
- Cast parts: controlled molecular weight determines mechanical performance
- Coatings: two-component polyurethane systems for film flexibility and adhesion
- Adhesives and sealants: peel strength and elongation in structural bonding
- Lubricants: polyester-based fluids where thermal stability is required
- It is effective in metalworking and gear oil formulations due to low volatility.
Good to know: Hydroxyl value and acid value are the primary specification parameters buyers use to qualify grades.
Commercial specifications
- Melt points vary across commercial ranges
- Technical-grade material in drums or bulk containers
- Molecular weight specifications range from low to high MW variants
