| Chemical Name | Polyether polyol |
Introduction & Specs
| Cas No. | 25322-69-4 |
| Molecular Weight | around 2000 |
| Introduction | 220A polyether polyol is a 2000 molecular weight polyether diol
with 2 functionalities. It is polyether synthesized with new catalyst, characterized by low unsaturation, narrow molecular weight distribution. Compared with conventional polyether, it shows wider practicability, stronger tear resistance, better deflection and elongation rate. |
| Applications | Widely used in high elastic resilient cold cure, microporous elastomer and semi-rigid polyurethane foam plastics. |

| Storage | 220A is hygroscopic and absorption of moisture would affect polyol reactivity and physical properties of resulting polymer. The material should be stored in sealed containers and in dry conditions, away from direct sources of heat. The recommended storage temperature is between 20~35℃. Opened drums must be reclosed tightly immediately after drawing-off material. | ||
| Shelf Life | 12 months from production date. | ||
