Arcol 11-34 polyether polyol is a 4,800-molecular-weight 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. It is compatible with most polyether polyols and can be blended with other diols, triols and polymer polyols to achieve desirable modifications of product properties.

Arcol 11-34 polyol is used in a broad range of urethane foam and other applications, including sealants, caulks, deck coatings, elastomers, tire fill and reaction injection molding (RIM). As with any product, use of Arcol 11-34 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
