The present invention relates to blowing agent compositions comprising the unsaturated halogenated hydroolefin 3,3,3-trifluoropropene (HFO 1243zf) and combinations including primarily 3,3,3-trifluoropropene (HFO 1243zf). The blowing agent compositions are useful in that they provide sufficient plasticization to permit the production of low density insulating thermoplastic foams with improved k-factor.
La présente invention concerne des compositions d'agent d'expansion comportant une hydrooléfine 3,3,3-trifluoropropène halogénée (HFO 1243zf) et des combinaisons comprenant principalement du 3,3,3-trifluoropropène (HFO 1243zf). Les compositions d'agent d'expansion sont utiles en ce qu'elles fournissent une plastification suffisante pour permettre la production de mousses thermoplastiques isolantes de faible densité avec un facteur k amélioré.
