Choosing between conventional polyol, POP or both
Many factories blend a conventional polyol with a share of POP to reach the hardness they need at a given density. The share depends on the foam you make; Foam Lab on our portal lets customers test a blend before they pour.
What to check on the TDS and certificate of analysis
- OH value — it sets how much isocyanate the formula needs.
- Water content — moisture in the polyol adds to the water in your formula.
- Acid value and viscosity.
- For POP: the solids content.
Storage
Keep drums closed and dry, out of rain and direct sun, and follow the SDS of the grade. Wet polyol changes the foam: it raises the isocyanate the formula needs and can cause scorch.
