Converge® polyol 212-20

Technical DataSheet | Supplied by Saudi Aramco

Converge® polyol 212-20 is a polyol produced from propylene oxide and carbon dioxide. It is an amorphous, linear, aliphatic polycarbonate diol. Carbon dioxide accounts for approximately 40% of the polyol mass. The aliphatic polycarbonate backbone delivers unique high performance to polyurethanes in terms of both strength and environmental resistance. It substantially increases the load bearing, tensile, and tear strength of flexible foams. It can also improve abrasion resistance. It has excellent compatibility with polyester polyols and isocyanates. Compatibility with polyether polyols is low to moderate; it is recommended that polyether-based systems are cured shortly after polyol blending. Converge® polyol 212-20 is compatible with all standard chain extenders, surfactants, and catalysts. It is a building block for a variety of polyurethane systems. It can be used in the preparation of elastomers and TPUs.
