Polyether Polyol(SG-3500)
Description
SG-3500 polyether polyol is a 3,500-molecularweight polyoxypropylene triol specially modified with ethylene oxide. The terminal end-groups have a high percentage of primary hydroxyl end-groups, giving it a relatively high rate of reactivity with isocyanates. SG-3500 is used in a broad range of urethane foam and other applications, including slabstock foam, seats, packing materials. As with any product, the use of SG-3500 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Storage
SG-3500 is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect product quality. This polyol can become quite viscous at low temperatures. For ease of handling, storage temperatures between ambient room temperature and 60¡ãC (140¡ãF) are recommended.
