Application to polyurethanes
Butadiene hydroxytelechelic oligomers PBHT

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.

The hydrocarbon structure of PBHT allows it to be used with hydrophobic diluents (bitumens,...
