Abstract
Compositions, methods, and uses of aragonite biobased polymer plastic compositions are presented having increased strength and stiffness as well as improved recyclability and/or biodegradability. The aragonite biobased plastic compositions include aragonite blended in a dispersion with a biobased polymer and optionally includes a petroleum-based polymer and/or a compatibilizer.
Claims10
A composition of a polymer dispersion comprising:
- restructured aragonite and one or more biobased polymers, wherein the restructured aragonite is present in an amount by weight between 9-45%, and wherein the restructured aragonite is a chemically recrystallized aragonite obtained by treatment with an unstructuring agent comprising a chelator or an acid to form an amorphous aragonite, followed by recrystallization;
- wherein the one or more biobased polymers are selected from polylactic acid (PLA), polyamide 11, polyamide 410 and blends thereof;
- wherein the composition has a flexural strength of or between 45 to 270 MPa;
- and
- wherein the composition has a flexural modulus of or between 2.0 to 7.5 GPa;
- wherein the restructured aragonite has a particle size distribution with D98 of 14-15 μm and a D10 of 1.0-1.5 μm.
