Abstract The present invention pertains to the use of at least one Brönsted superacid or metal salt of said Brönsted superacid with a DeltaGacid value of 316 kcal/mol or less, as a heat and/or colour stabiliser for polyvinyl halide resin compositions. The superacid is not a perchlorate or a trifluoromethane sulphonate. The metal in the metal salt of the Brönsted superacid is preferably selected from the group consisting of alkali metals, alkali earth metals, transition metals, lanthanide metals, actinide metals, Al, Ga, In, TI, Ge, Sn, Pb, and Sb.
