Diisocyanates: The Chemical Behind Polyurethane and its Many Uses

Posted on 1/30/2019 9:42:19 AM By ASC

Polyurethane is ubiquitous in today’s world. Soft foams, hard foams, coatings, elastomers, sealants, appliances, apparel and more are based on these chemical building blocks, and they are the basis of the polyurethane adhesives that go into the manufacture of an even longer list of everyday products. 

Polyurethane materials are almost everywhere to be found in homes, but also automobiles, and include everything from automobile coatings to headrests, upholstery, and insulation. Seals, bonds, and durable finishes all depend on the products we can produce from this group of chemicals.

The American Chemistry Association points out just how much we rely on Diisocyanates for the things we take for granted every day. The reason why they are so widely used is simple. These chemical building blocks react with a wide variety of other chemicals resulting in the massive range of polyurethane materials we encounter. During processing, Diisocyanates must be handled with caution, but the chemical reactions they undergo means that the chemical is changed, becoming harmless in its final polyurethane format.
