Polyethylene adipate

Polyethylene adipate (CAS 24938-37-2) is a polyester polyol produced by condensing ethylene glycol with adipic acid. It functions as a base polymer and plasticizing component across multiple industrial sectors.

This material provides essential flexibility, compatibility, and chain-extension capability in various polymer systems. In polyurethane manufacturing, it serves as a polyol building block for producing flexible foams and elastomers.

It is also used for cast parts where controlled molecular weight determines final mechanical performance. Coatings formulators incorporate it into two-component polyurethane systems to improve film flexibility and adhesion.

The product ensures superior performance on metal and plastic substrates. In adhesives and sealants, it contributes significantly to peel strength and elongation in structural bonding applications across the industry.

Lubricant manufacturers use polyester-based fluids derived from this material where thermal stability is required. It is particularly effective in metalworking and gear oil formulations due to its low volatility.

Polyethylene adipate is supplied as a waxy solid or viscous liquid depending on molecular weight grade. Typical melt points vary across commercial ranges to meet specific industrial processing requirements.

Standard supply forms include technical-grade material in drums or bulk containers. Molecular weight specifications commonly range from low to high MW variants tailored to specific application requirements.

Hydroxyl value and acid value are the primary specification parameters buyers use to qualify grades. These metrics are essential for qualifying the material for polyurethane or coating applications.
