Polyether polyols CHE-828D are copolymerized from the ring-opening of propylene oxide and ethylene oxide with active hydrogen compounds as initiator under the effect of the catalyst. The products are typical BHT-free and amine-free high reactivity polyether polyols with high molecular weight. The products are characterized by low odor.They are used to prepare high resilient and cold-curing foams for cushions of bicycle, motorcycle and car and steering wheels.And they can also be prepared for foams applied to fill the dashboard.
