General Characterization

Arcol PPG-4000 polyol is a 4,000-molecular-weight diol based on propylene oxide.

Storage Conditions

Arcol PPG-4000 polyol is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect product quality. This polyol can become quite viscous at low temperatures. For ease of handling, storage temperatures between 20°C (68°F) and 60°C (140°F) are recommended.
