Chloride-Process Titanium Dioxide CR-350 – High-Performance Pigment for Advanced Plastic and Polymer Applications
Titanium Oxide Rutile Pigment CR-350, produced via the advanced chloride process, is engineered as a premium-grade white pigment specifically formulated to meet the exacting standards of the modern plastics industry. Renowned for its exceptional brightness, blue undertone, and superior dispersibility, this pigment is designed to deliver outstanding opacity, color consistency, and durability in a wide array of polymer systems under demanding processing conditions.
Primary Industrial Applications in Polymer Manufacturing
This high-performance pigment is utilized to achieve superior aesthetic and functional properties in engineered plastic products:
-
Engineering Plastics and High-Temperature Polymers: It is extensively incorporated into polycarbonate (PC), ABS, nylon (PA), and PBT for automotive parts, electrical enclosures, and consumer electronics, where thermal stability and color fidelity are critical.
-
High-Quality Polyolefin Applications: The pigment is effectively used in injection-molded and extruded polyethylene (PE) and polypropylene (PP) products, including food containers, household appliances, and technical components, ensuring brilliant whiteness and excellent processability.
-
Masterbatch and Compound Production: CR-350 serves as the ideal choice for manufacturing high-concentration white and color masterbatches, offering excellent dispersion and consistent tinting strength for let-down in various polymer bases.
-
Films and Fibers: It is applied in biaxially oriented polypropylene (BOPP) films, packaging films, and synthetic fibers to achieve the required opacity, brightness, and UV barrier properties.
Key Technical Characteristics and Performance Advantages
The CR-350 grade provides a suite of engineered benefits crucial for premium plastic fabrication:
-
Neutral Blue Undertone and High Brightness: Delivers a clean, bright white base with a neutral to slightly blue shade, ideal for pure whites and accurate color matching in tinted applications.
-
Exceptional Dispersibility and Ease of Processing: Its optimized inorganic surface treatment ensures rapid and uniform dispersion within the polymer melt, reducing energy consumption and improving production efficiency.
-
Superior Thermal and Process Stability: Exhibits outstanding resistance to yellowing and degradation at high processing temperatures, maintaining color consistency in demanding extrusion and molding operations.
-
Excellent Weathering and Light Fastness: Provides enhanced protection against UV degradation, extending the service life and appearance retention of outdoor and exposed plastic products.
-
Low Volatile Content and High Purity: The chloride process ensures a product with minimal impurities, leading to better polymer compatibility and reduced risk of defects.
