Soft Foam Polyether Polyol
- Product
- Polyether Polyols for High Resilience Soft Foams
Overview
These high-molecular-weight polyether polyols are made for high-resilience (HR) and molded flexible foams. The grades SEP-330N, SEP-828L, SEP-330L, SEP-628, SEP-360N and SK-350D have hydroxyl values of 26–36 mgKOH/g.
Also known as
High-resilience polyols; HR foam polyether polyols

- Base polyols for polymer polyols (POP)
Packaging
210 kg/drum; 1000 kg/IBC; ISO tank or flexitank on request.
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.
