Polyether Polyol XS-330S
XS-330S polyol is a highly reactive trifunctional polyol. The polyol has high content of primary hydroxyl, and the good stability of foaming, low VOC.

XS-330S polyol is widely used to produce the high rebound resilience foams made by cold molding and continuous-foaming, integral-skin products made by iXSection molding.
XS-330S 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-330S 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-330S 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.
