Polymer Polyol XS-3628
XS-3628 polyol is a kind of polymer polyol, composed of highly reactive polyether polyol and styrene-acrylonitrile graft copolymer.
| Appearance | White viscous liquid |
| Hydroxyl number (mgKOH/g) | 28±3 |
| Water (%) | ≤0.05 |
| pH | 5 – 9 |
| Viscosity at 25℃ (mPa.s) | ≤2500 |
XS-3628 polyol is used to produce cold cure high resilient foams, which have better tear resistance and rebound resilience, comfortable handle as well.
XS-3628 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-3628 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-3628 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.
