Soft Foam Polyether Polyol
- Product
- Polyether Polyol 330N
Overview
Polyether polyol 330N is a high-activity polyether triol with a molecular weight of about 5000. It is based on glycerol with propylene oxide and an ethylene oxide cap, which gives it a high content of primary hydroxyl groups and high reactivity.
Also known as

Storage
Store in sealed containers in a dry place at 15–35 ℃. Polyols absorb moisture, so keep containers closed; a nitrogen blanket is recommended for bulk storage.
