4. Application to polyurethanes

4.1 Implementation

Hydroxytelechelic polybutadienes are most often used as flexible polyols in polyurethane systems. Given the polyfunctional nature of free-radical products, they are mainly processed by casting or spraying after passing through a static or dynamic mixer.

In this way, processing is generally carried out by mixing two components (part A and part B) in a low-pressure casting machine.

For more information on polyurethane chemistry and processing, please refer to article Polyurethanes.

Note :

In this article, we have adopted the international spelling "polyurethane" recommended by IUPAC. Polyurethane" is only used in France.
