    Abstract: The invention concerns blowing agents mixtures containing at least a partially fluorinated hydroncarbon and the usual auxiliaries and additives, in which the inert gas content, measured in the vapour phase of the blowing agent or blowing agent mixture, should not exceed 1.5% by volume. The blowing agent mixture can be used to manufacture foam products from thermnoplastics, especially foamed polystyrene.
