Values shown are typical and indicative only. Actual figures vary by grade and producer — a batch-specific certificate of analysis is issued with every shipment and should be used for design and compliance purposes.
Values marked “confirmed on TDS” are grade-defining and are stated on the technical data sheet issued for your enquiry, rather than published here.

Storage & handling
Store in sealed containers under dry conditions, 15–30 °C, away from direct sunlight. Polyols are hygroscopic — absorbed moisture reacts with isocyanate and causes foam defects. Blanket with dry nitrogen where bulk storage is used.
