| What Is Case Polyether Polyol SE-220A? |
Case polyether polyol SE-220A is a type of polymer polyether diol initiated by propylene glycol with a molecular weight of 2000. SE-220A has a wide range of applications, including:
The product has a functionality of 2, meaning it has two reactive hydroxyl groups per molecule. It is stable at ambient temperatures but can undergo oxidation at high temperatures. For storage, it should be kept at ambient temperatures in a cool, dry place, with the container sealed to prevent moisture ingress. Exposure to heat and open flames should be avoided. The storage period is 12 months. |
