Plastic compositions
The subject matter discloses a plastic composition comprising a first component and a second component, the first component comprising an organic element and a thermoplastic element and the second component comprising cross-linked hydrocarbon elastomers. The subject matter further discloses a process comprising mixing while heating under shear forces a first component comprising organic material and thermoplastic material with a second component comprising cross-linked hydrocarbon elastomers; to obtain a melt; processing the melt, the processing comprises at least cooling the melt to obtain a plastic composition comprising: organic element; thermoplastic element; and at least one cross-linked hydrocarbon elastomer element.
