Polyether polyols CHE-5603 are polymerized from the ring-opening of propylene oxide with active hydrogen compounds as initiator under the effect of the catalyst. The products are general polyether polyols without BHT and applied widely. They are prepared for slabstock foams, mattress, furniture and packing materials and can be used to produce low, moderate and high density foams. They are also especially fit for sponges used for flame lamination to improve tensile and tear strength.
