ISONATE™ 125 M Isocyanate

A white to light yellow crystalline solid (below melting point) of high purity and low acidity, containing approximately 97% 4,4'-diphenylmethane diisocyanate and 3% 2,4'-diphenylmethane diisocyanate. This product is used in applications where its di-functionality and low acidity can advantageously yield totally linear thermoplastic urethane elastomers and elasto-plastic products. Together with longer chain polyethers, polyesters, or other polyols, high performance polymers may be compounded in a wide range of hardness for such applications as microcellular elastomers, coatings, adhesives and sealants.
