Plastic Resins
Plastic Resins are small granular raw materials used as a base material in the manufacturing process of various plastic products. They can be produced from various types of polymers, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), and many others. Plastic Resins can be processed through extrusion, injection, or molding to form a wide range of products, from plastic packaging, bottles, pipes, to automotive parts and electronic products.
Fillers & Additives
Fillers & Additives are additional materials added to polymers or other plastic raw materials during the production process to improve performance or modify the physical and chemical properties of the plastic products.
Fillers are small particles added to plastic raw materials to increase strength, rigidity, or wear resistance. Some examples of fillers are wood powder, glass fibers, stone powder, and metal powder. Additives are chemical substances added to plastic raw materials to modify the product properties, such as flame resistance, UV resistance, strength, color, and many more. Some examples of additives include antioxidants, UV stabilizers, dyes, and plasticizers. Both fillers and additives can significantly improve the performance and quality of plastic products, and their selection and combination depend on the specific application requirements of the final products.
Pigments
Pigments are raw materials used to add color to various products such as paints, inks, plastics, and cosmetics. They come in a wide range of colors and can be either organic or inorganic compounds. Inorganic pigments are derived from minerals and offer excellent stability and lightfastness. Examples include titanium dioxide (white), iron oxides (red, yellow, brown), and chromium oxide green. Organic pigments are carbon-based and provide vibrant colors with high tinting strength. Examples include phthalocyanine blue and green, quinacridone, and azo pigments. The selection of pigments depends on the desired color, performance requirements, and compatibility with the material they will be used in.
