Polypropylene Glycol 4000 (PPG 4000)

Description

What is Polypropylene Glycol 4000 (PPG 4000)?

Polypropylene Glycol 4000 (PPG 4000) is a high molecular weight polyether polyol derived from propylene oxide. With a molecular weight of approximately 4000, it is widely used in the production of polyurethane elastomers, adhesives, coatings, sealants, and lubricants.

This BHT-free polyol offers excellent reactivity with isocyanates due to its low phosphoric acid content, making it a reliable intermediate in PU and other industrial applications. PPG 4000 also demonstrates excellent blending and lubrication properties, allowing it to be used as a functional fluid in multiple formulations.
