Stabilizer combination for halogen-containing thermoplastic resin compositions

摘要

The present invention relates to a stabilizer composition for halogen-containing thermoplastic resins, the stabilizer composition comprising (a) calcium hydroxide and/or calcium oxide which may optionally be surface-modified; and (b) a hydroxyl group-containing isocyanurate. This stabilizer composition is particularly suited for weather-resistant halogen-containing resin compositions, such as rigid PVC.
