Toughened polyolefins and methods used to produce toughened polyolefins in presence of a bio-filler. These materials can substitute traditional thermoplastic polyolefins known as TPOs or mineral filled TPOs. Exemplary compositions include a phase based on α-olefin elastomers and the use of biobased fillers. The bio-based filler used, can be a material rich in elemental carbon content. The use of additives is of regular usage for these compositions as they may be related to coupling agents, UV absorbers, light stabilizers, antioxidants, and so forth. These composition offer a remarkable lower density compared to traditional TPOs compositions altogether with bio-based value-performance addition.
A thermoplastic polyolefin composition comprising a polypropylene (PP), an α-olefin copolymer, more than 0.5% and up to 2% by weight of a β nucleating agent, and biocarbon.
A thermoplastic polyolefin composition having a melt flow index (MFI) larger than 15 g/10 minutes, the thermoplastic polyolefin composition comprising by weight percent:
A thermoplastic polyolefin composition having an impact greater than 500 J/m and an elongation at break higher than 200%, the thermoplastic polyolefin composition comprising by weight percent:
A method of manufacturing a thermoplastic polyolefin composition, the method comprising:
