The present invention relates to a flexible molded skin as part of a composite structure for an airbag cover, and to a composition for producing such a skin using slush molding. The composition and flexible molded skin comprise at least one thermoplastic plasticized vinyl polymer, and a tear promoting agent selected from the group of one or more particulate blowing agents, inorganic mineral materials, organic filler materials and microspheres or a mixture of two or more of the afore mentioned materials. The particles of the particulate tear promoting agent have an average particle size of between 0.005 and 50 µm, preferably between 0.005 and 40 µm.
