There are various types of coloring agents for plastics. Common types of plastic coloring agents include the following: 1. Pigment-based coloring agents: These are coloring agents in powder or paste form, known for their vibrant colors and excellent light resistance. Common pigments include organic and inorganic pigments. 2. Dye-based coloring agents: These are liquid coloring agents used for transparent plastics. They can add color without compromising transparency. 3. Masterbatch: This is a mixture where coloring agents are uniformly dispersed in plastic pellets, making it easy to use in injection molding or extrusion processes. Plastic coloring agents play an important role in customizing the color and properties of products. The choice of coloring agent can be tailored to the type of plastic and the requirements of the product. For resin coloring in injection molding, you can rely on our company, which can also help you investigate colors from products.

By incorporating eggshells, we can reduce the amount of plastic used and create environmentally friendly products. Eggshells are typically disposed of as industrial waste, but by incorporating them into plastic, they can be effectively utilized. By incorporating eggshells, we can reduce the amount of plastic used, lower environmental impact, and create products that are kind to the Earth. Additionally, this contributes to the reduction of greenhouse gases, decreases the energy used in the manufacturing process, and supports the SDGs goal of "sustainable consumption and production patterns." Furthermore, we can create products that have durability and moldability comparable to existing resins. Eggshells are usually disposed of as industrial waste, but by incorporating them into plastic at a weight-based ratio of over 50%, they can be effectively utilized. Products made by incorporating eggshells into plastic can be used in a wide range of applications, including toys, household goods, food containers, electrical appliances, and automotive parts.
