The selection of pigments for plastic products has become an important consideration for domestic and foreign manufacturers. As the demand for brightly colored and visually appealing plastic applications continues to grow, pigment selection has become a critical aspect of the production process. As a result, the pigments used in plastic production vary widely depending on geographic location and specific market preferences. Domestic markets prioritize cost and local preferences, while international markets prioritize performance and global appeal, reflecting a more complex decision-making process. As global demand for plastic products continues to grow, understanding and adapting to these diverse pigment selection practices is critical for manufacturers who want to thrive in domestic and international markets. In the domestic market, plastic pigment selection emphasizes factors such as cost-effectiveness, regulatory compliance and local consumer preferences. Domestic manufacturers tend to rely on readily available pigments that comply with national regulations and environmental standards. Additionally, color trends and consumer preferences play a key role in the selection process as the domestic market aims to meet the needs and tastes of local consumers. In contrast, abroad, the choice of plastic pigments reflects broader considerations. International markets often prioritize factors such as technical performance, sustainability and color consistency during the pigment selection process. Foreign manufacturers may invest in innovative pigment technologies to improve the visual appeal and durability of their plastic products in global markets. The disparity in pigment selection around the world highlights the multiple factors that influence plastics manufacturers’ choices.
