Product type
White masterbatch is a concentrated mixture of pigments and additives encapsulated in a carrier resin, typically used to impart whiteness and opacity to plastic products. It is formulated to be easily dispersed in various polymer matrices during the manufacturing process. White masterbatches are commonly utilized in the production of plastic items, providing uniform color and enhancing the aesthetic appeal of the final products.
| Base resin | Polyethylene, polypropylene, or polystyrene |
| Pigment type | Titanium dioxide is commonly used |
| Concentration | Typically 30% to 70% pigment loading |
| Carrier resin | Compatible with the final polymer |
| Melt flow index | Varies based on application, typically 1 to 20 g/10 min |
When selecting white masterbatch, consider the type of base resin that will be used in your application to ensure compatibility. Specify the desired pigment concentration to achieve the required opacity and whiteness. Additionally, inquire about the melt flow index to match the processing requirements of your manufacturing equipment. Certifications for food safety or environmental compliance may also be relevant depending on the end use of the plastic products.
