Typical properties only; not to be construed as sales specifications. All grades: protect from atmospheric moisture, store in a dry place and avoid prolonged exposure to heat and air.
What do these values mean?
- Molecular weight — the size of the polyol molecule. Larger molecules generally give softer, more elastic foam.
- Hydroxyl number — how many reactive OH groups the polyol carries; it sets how much isocyanate the formulation needs. A lower number means a larger molecule.
- Viscosity — how thick the liquid is, which affects pumping and mixing.
- Water — moisture content. Low, consistent water keeps foaming predictable.
- Color (APHA) — how clear and colourless the liquid is; lower is clearer.
