White Masterbatch: The Ultimate Solution for Premium White Plastic Products
In the global plastics industry, achieving a pure, bright, and consistent white finish is often a challenge. Our White Masterbatch is an engineered functional additive designed to deliver superior whiteness, opacity, and mechanical integrity for the most demanding packaging and industrial applications. Utilizing premium-grade Rutile Titanium Dioxide (TiO₂) as the core pigment, combined with a precisely selected carrier resin and advanced dispersing agents, this masterbatch ensures complete coverage and long-lasting color stability across various polymer matrices.
Product Overview
White masterbatch is a highly concentrated mixture of titanium dioxide, carrier resin, and additives. Unlike direct powder pigment addition, our pelletized form offers unparalleled cleanliness and ease of handling. It provides exceptional hiding power, effectively masking the natural color of base resins like LLDPE, HDPE, PP, and PET, while enhancing the overall brightness and visual appeal of the final product.
Core Advantages
1. Ultimate Opacity & Brilliant Whiteness
Our formulation incorporates finely dispersed rutile TiO₂, which offers a refractive index of 2.7 — significantly higher than most fillers. This results in 3 to 5 times stronger hiding power compared to conventional pigments, ensuring that even thin films achieve a flawless, opaque white finish .
2. Superior Dispersion Performance
With advanced twin-screw compounding technology and nano-level particle size control (around 0.35μm), our white masterbatch guarantees homogeneous distribution throughout the polymer melt. This eliminates common defects such as color streaks, fish eyes, or pigment agglomeration, ensuring a smooth surface on blown films, injection-molded parts, and extrudedeets sh.
3. High Compatibility & Process Stability
Designed for versatility, our white masterbatch is compatible with a wide range of thermoplastics including PE, PP, and PET. Its thermal stability allows it to withstand high processing temperatures without degradation, maintaining consistent color performance even under prolonged production cycles .
4. Eco-Friendly & Food-Safe Options
We offer specialized grades that are lead-free, heavy-metal free, and fully compliant with EU environmental regulations and international food contact standards (such as FDA and RoHS). This makes our product ideal for food packaging, pharmaceutical containers, and household goods where safety and sustainability are paramount .
Wide Range of Applications
Our white masterbatch is the preferred choice for manufacturers seeking reliability and quality. It is widely used in:
- Packaging Films: Blown and cast films for food, pharmaceuticals, and consumer goods.
- Blow Molding: Bottles and containers for detergents, cosmetics, and beverages.
- Injection Molding: Houseware items, caps, closures, and automotive components.
- Pipe and Sheet Extrusion: Architectural sheets, foam boards, and industrial profiles .
