Vinyl chloride polymer compositions with reduced combustibility and reduced smoke formation under conditions of fire.

摘要

The invention pertains to vinyl chloride polymer compositions with an oxygen index according to ASTM D 2863 of at least 60 and reduced smoke formation under conditions of fire. This is achieved in that the composition contains 0.05-5 parts by weight per 100 parts by weight of vinyl chloride polymer of a zinc titanate that consists to a large extend of zinc titanate possessing the spinel structure.
