FILLED POLYPROPYLENE COMPOSITIONS AND RELATED AUTOMOTIVE COMPONENTS

摘要

The present disclosure provides a filled composition made from and/or containing (A) a first polymer composition made from and/or containing (i) a heterophasic polypropylene copolymer and (ii) a polypropylene blend, and (B) a biofiller composition made from and/or containing a cellulose-based biofiller. The filled composition can additionally be made with and/or contain an elastomeric ethylene copolymer composition. Optionally, the filled composition can further be made with and/or contains a grafted polyolefin composition. The filled composition is useful in making automotive components.
