HYDROFLUORO OLEFIN PROPELLANT IN A POLYURETHANE FOAM COMPOSITION

A process and composition are described for the inclusion of polyether polyols in concentrations greater than 10% loading on the B-side formulation with a catalyst package less than 1% loading on the B-side formulation. In one specific example, the use of glycerin as a fluorine ion scavenger is util...

More Information
Summary:A process and composition are described for the inclusion of polyether polyols in concentrations greater than 10% loading on the B-side formulation with a catalyst package less than 1% loading on the B-side formulation. In one specific example, the use of glycerin as a fluorine ion scavenger is utilized to improve performance of the polyurethane systems through a twelve-month shelf life. L'invention concerne un procédé et une composition pour l'inclusion de polyéther-polyols en des concentrations supérieures à 10 % de charge sur la formulation côté B avec un conditionnement de catalyseur inférieur à 1 % de charge sur la formulation côté B. Dans un exemple spécifique, l'utilisation de glycérol en tant que capteur d'ions de fluor est utilisée pour améliorer les performances des systèmes de polyuréthane par l'intermédiaire d'une durée de conservation de douze mois.
