Recycling halogen-free thermoplastics, stabilized plastic compositions, and methods for stabilizing molding compounds and molded parts

摘要

The present invention relates to a method for stabilizing a halogen-free thermoplastic recycled material or pre-damaged plastics against oxidation, heat and/or chemical degradation. In the process according to the invention, at least one alditol or cyclitol is introduced as a component into a halogen-free thermoplastic recycle, and optionally additionally at least one primary antioxidant and/or at least one secondary antioxidant is added to the halogen-free thermoplastic recycle. Is introduced. The plastic recycled material according to the invention can be stabilized in a very environmentally friendly and inexpensive manner with a high level of effectiveness against oxidation, heat, and/or chemical degradation. The invention further relates to corresponding recycling-based plastic compositions and molding compositions and molded parts produced therefrom. The present invention further relates to stabilizing compositions used for stabilizing halogen-free thermoplastic recyclers against oxidation, heat, and/or chemical decomposition, and their use.
