Polyether Polyol XS-8243
XS-8243 polyol is a conventional rigid polyether polyol initiated with sucrose. The polyol has high functionality and foams based on the polyol have good dimensional stability.

XS-8243 polyol is used to produce conventional rigid foams, as refrigerator, cold cabinet and sandwich panel etc.
XS-8243 polyol is slightly hygroscopic and may absorb moisture, which would affect the properties of the products. The polyol should be stored in sealed containers and in dry conditions, away from direct sources of heat. Polyol is supplied in drums and tank trucks; or confer with supplier.
XS-8243 polyol has a very low odor of acute toxicity and does not present a significant health hazard to users. Normal standards of industrial hygiene should however be observed when handling this chemical. Suitable protective clothing and eye protection must be worn to avoid unnecessary contacts and accidental ingestion. In case of eye contact, seek medical attention.
XS-8243 polyol will burn under certain condition and can explode if heated to decomposition temperature in a confined area. Polyols fires can be extinguished with water fog, carbon dioxide or dry chemicals.
