White masterbatch is a type of plastic color concentrate that incorporates white pigments, primarily Titanium Dioxide (TiO₂), into a polymer carrier resin like PE (Polyethylene) or PP (Polypropylene). This compound is integral to enhancing both the appearance and performance of plastic products.
Key Benefits Include:
High opacity and brightness
Excellent UV resistance
Even color dispersion
Improved processing efficiency
A well-designed white masterbatch formulation ensures consistent color quality and high performance across various plastic manufacturing processes.
TiO₂ is the most critical ingredient in white masterbatch. Its high refractive index gives plastics a clean and bright white finish. The percentage of TiO₂ directly impacts the masterbatch’s opacity, brightness, and UV resistance.
At Xinwancai Masterbatch, we use high-purity TiO₂ with fine dispersion to ensure maximum whiteness, durability, and long-term color stability. Our formulations are suitable for both indoor and outdoor applications, including food-safe and anti-UV white masterbatches.
White masterbatch is utilized across multiple plastic manufacturing processes to ensure consistent color and high performance. Some key applications include:
Plastic Packaging Films: Enhances whiteness, printability, and opacity of the plastic film.
Injection Molding: Ideal for containers, medical parts, and caps requiring uniform color.
Blow Molding: Perfect for white bottles, drums, and jerrycans, providing opaque and bright surfaces.
Sheet and Pipe Extrusion: Ensures color consistency and UV resistance for pressure-resistant plastic products.
Food and Agricultural Plastics: Requires food-grade white masterbatch with reliable UV stabilization.
No matter the process—whether it’s plastic film, blow molding, or extrusion-grade masterbatch—Xinwancai offers customized formulations to meet your specific needs.
The carrier resin used in the masterbatch affects how it blends with the base polymer. Proper resin compatibility ensures optimal dispersion and consistent product quality.
PE (Polyethylene): Best for applications like film blowing, shopping bags, and flexible packaging.
PP (Polypropylene): Ideal for rigid containers, sheets, and fibers.
Custom Resins: We also offer solutions for engineering plastics, biodegradable materials, and high-melt-index carrier resins.
Xinwancai Masterbatch supplies polyethylene masterbatch granules for a variety of industrial applications.
Using premium white masterbatch significantly improves surface gloss, color coverage, and overall appearance. It is particularly effective in enhancing opacity in thin plastic films, where transparency needs to be minimized. Our advanced dispersion techniques ensure that even a small amount of high-brightness white pigment delivers remarkable results.
Before selecting a white masterbatch supplier in China, buyers should evaluate several important factors:
