In an embodiment, a natural rubber-based ABS—target polymer blend includes natural rubber-based ABS powder combined with a set of target polymers (e.g., polycarbonate (PC)). A natural rubber-based ABS powder production process includes producing grafted natural rubber; and mixing the grafted natural rubber with a set of grafted polybutadiene rubbers. The set of grafted polybutadiene rubbers includes at least one grafted polybutadiene rubber having a particle size that is significantly different than the grafted natural rubber particle size. In an embodiment, the grafted natural rubber exhibits a large particle size; a first grafted polybutadiene rubber exhibits a small particle size; and a second grafted polybutadiene rubber exhibits a medium particle size between the large and small particle sizes. Natural rubber-based ABS—target polymer blends in accordance with the present disclosure can exhibit generally equivalent or increased impact and/or tensile strength compared to other non-natural or synthetic rubber-based ABS blends.
