SD-820,Using special initiator and terminated with ethylene oxide with high reaction activity is a polyether polyol which used for the preparation of polyurethane sole system the characteristics are as follows:
1、The molecular weight of about 4000 with a narrow molecular weight distribution coefficient the molecular weight distribution coefficient lower than 1.20。
2、Terminated with ethylene oxide which accounting for 21%-25%the primary hydroxyl content is more than 80%,with a higher reaction activity reducing the amount of the catalyst.
3、No BHT no amine products low odor significantly decreased the content of VOC.
