Polyol resin and isocyanate

Polyol resin and isocyanate are the most vital two components of many industrial applications for producing high strength and durable service items. The combination of these materials in a particular manner also allows it to be suited for a variety of applications we encounter in our daily lives. Let’s find out a little more about these materials, how they work in conjunction with each other, and their significance in different industries.


The chemistry behind polyol resin and isocyanate reactions

This reaction between an isocyanate and a polyol resin is called the polyurethane reaction. This is a key chemical reaction — a process. In this reaction, isocyanate molecules bond with hydroxyl groups on the polyol resin. When they do, they form special types of bonds called urethane linkages. These links are crucial as they provide the polyurethane with its unique properties. For instance, the material is now strong enough to withstand pressure but also flexible so that it can adjust just a little without breaking. This reaction rate is influenced by the temperature, as well as the type of polyol resin and isocyanate used. That means manufacturers can have control over the outcome of the final product.
