General Characterization

Arcol HS-200 polyol is a premium high-load polymer polyol with the highest polymer solids content of commercial polyols.

Storage Conditions

Arcol HS-200 polyol is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect processing.
This polyol can become quite viscous at low temperatures. For ease of handling, storage temperatures between 20°C (68°F) and 60°C (140°F) are recommended.
The shelf life is twelve months after receipt of material by customer, when stored in sealed original containers under conditions stated above.







Notes:
When using Arcol HS-200 polyol as a replacement for Arcol HS-100 polyol in conventional formulations, the amount of polymer polyol needs to be adjusted (reduced) by approximately 10% to compensate for the higher solids in HS-200. To calculate the amount of HS 200 needed multiply the amount of HS-100 by 0.9 (90%) and increase the amount of base polyol to 100 minus the amount of HS-200. The amount of isocyanate may need to be adjusted slightly depending on the base polyol used. Typically no other formulation changes are needed. See example 1 above.
When using HS-200 as a replacement for Arcol UHS-150 polyol in conventional or High Resilience formulations typically no adjustments to the formulation are needed. See example 2 above.
When using HS-200 as a replacement for HS-100 in Ultracel U-3000 polyol formulations the amount of polymer polyol needs to be adjusted (reduced) to compensate for the higher solids in HS-200 and solids present in U-3000. To calculate the amount of HS-200 needed multiply the amount of HS-100 by 0.87 (87%) and increase the amount of U-3000 polyol to 100 minus the amount of HS-200. The amount of isocyanate will need to be adjusted slightly. Typically no other formulation changes are needed. See example 3 above.
It is advisable to calibrate the polyol stream when switching to HS-200 to account for the difference in viscosity.
