Applications
PPG-425 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.
PPG-425 is a 425-molecular-weight polypropylene glycol. The terminal end-groups are predominantly secondary hydroxyls and have a relatively low reactivity. It is compatible with some polyether polyols and can be blended with other diols or triols to achieve desirable modifications of product properties.
Package and Storage
Package: 1000 Kg / IBC drum or 200 Kg / metal drum (Net weight).
