PE white masterbatch is a concentrated mixture of titanium dioxide (TiO2) pigment dispersed in polyethylene (PE) resin. It's a widely used additive in plastic manufacturing to impart a bright white color and increase the opacity of various plastic products. This masterbatch is a cleaner and more efficient way to whiten plastic compared to using raw pigments or powders.
- Composition: PE white masterbatch consists of a high concentration of TiO₂ pigment (often up to 70-80%) and a PE carrier resin. It may also include other additives for specific properties like UV resistance or food-grade compliance.
- Function: It's used to achieve a bright, consistent white color and increase the opacity of plastic products. This is crucial for applications where whiteness and light-blocking capabilities are desired.
-
Benefits:
- Enhanced dispersion: The masterbatch ensures better dispersion of the pigment in the plastic, leading to a more uniform color and a smoother surface finish.
- Cost-effectiveness: It can be more cost-effective than using raw pigments, especially when considering factors like handling and dispersion.
- Improved performance: White masterbatch can improve the UV resistance, heat resistance, and other properties of the final plastic product.
- Ease of use: It comes in granular form, making it easy to handle, store, and incorporate into the plastic manufacturing process.
-
Applications: PE white masterbatch is used in various plastic manufacturing processes, including:
- Film blowing: For producing films used in packaging and other applications.
- Injection molding: For creating various plastic parts and components.
- Extrusion: For producing profiles, sheets, and other extruded plastic products.
- Other applications: It is also used in the production of fibers, non-woven fabrics, and various other plastic products.
