White masterbatch, also known as white color concentrate or white pigment masterbatch, is an additive used to color various plastic products. It is typically composed of a high proportion of white pigment (such as titanium dioxide, TiO2) mixed with a carrier resin, existing in the form of a concentrate that allows for uniform dispersion and coloring during the plastic processing.
Composition of White Masterbatch
Base Resin: Typically uses resins compatible with the target product, such as PE, PP, ABS, PS, PVC, etc., to ensure good compatibility and dispersion.
Pigments: The main component is titanium dioxide (TiO2), widely used for its excellent hiding power and whiteness.
Additives: May include dispersants, antioxidants, ultraviolet absorbers, gloss agents, stabilizers, etc., to enhance the product’s processing performance and service life.
Classification
Classification by Carrier Type:
1. Specific Carrier White Masterbatch: Utilizes the same or compatible resin as the final product material, such as for specific applications in PE, PP, ABS, etc.
2. Universal White Masterbatch: Typically uses PE as a carrier due to its good compatibility and flow properties, suitable for various plastic materials.
Classification by Application Field:
1. Industrial White Masterbatch: Used in manufacturing packaging materials, pipes, construction supplies, etc., with an emphasis on weatherability and stability.
2. Consumer Goods White Masterbatch: Employed in household appliances, toys, daily products, etc., focusing on appearance and safety.
Applications
● Plastic Product Coloring: White masterbatch is ideal for imparting white or light shades to plastic products. It is commonly used in producing white home appliances, toys, containers, and plastic bags.
● Packaging Materials: The food and cosmetics industries extensively use white packaging materials like bottles, boxes, and films. White masterbatch offers high brightness and opacity while meeting food safety standards.
● Textile Fibers: In synthetic fiber production, white masterbatch provides a uniform white coloring effect, commonly used in manufacturing white garments, household textiles, and industrial textiles.
● Building Material: White PVC pipes, profiles for doors and windows, floors, and other building supplies often utilize white masterbatch to achieve a clean, elegant appearance.
● Electronic Products: White masterbatch is used in the electronics industry to produce white casings and components such as mobile phone cases, computer peripherals, and appliance enclosures, enhancing the visual appeal of the products.
● Agricultural Field: The production of agricultural films also involves white masterbatch to increase the film’s reflectivity and longevity.
● Medical Devices: In the medical industry, certain instruments and tools require white masterbatch to meet hygiene and easy-to-clean requirements.
