Overview
Universal Brown Masterbatch is a pre-dispersed pigment concentrate used to color plastics uniformly. It consists of high-quality pigments, carriers, and additives, ensuring consistent coloration and ease of processing. The masterbatch is compatible with various polymers like polyethylene (PE), polypropylene (PP), and ABS. Masterbatches are preferred over raw pigments due to their handling convenience, reduced dust pollution, and precise color control. They are widely adopted in industries requiring mass production of colored plastic products, offering cost-efficiency and environmental benefits.
Physical and Chemical Properties
The masterbatch typically appears as small granules or pellets with a uniform brown hue. Its density ranges between 1.1-1.3 g/cm³, depending on the carrier resin used. The product exhibits excellent thermal stability, making it suitable for high-temperature processing methods like injection molding and extrusion. Solubility is limited to molten polymers, and it is insoluble in water or common solvents. Key properties include high color strength, which ensures vibrant shades even at low dosages, and superior dispersion characteristics, preventing speckling or streaking in the final product.
Main Applications
Universal Brown Masterbatch is extensively used in the packaging industry for producing brown plastic bags, films, and containers. Its UV resistance makes it suitable for outdoor applications like garden furniture and automotive components. In the consumer goods sector, it colors items such as kitchenware, toys, and storage bins. The masterbatch is also employed in agricultural films and construction materials, where durability and color consistency are critical.
Safety and Storage
While handling the masterbatch, workers should wear protective gloves and masks to avoid skin contact or inhalation of dust particles. Although non-toxic, prolonged exposure to pigment dust may cause respiratory irritation. Storage recommendations include keeping the product in a cool, dry environment, ideally below 30°C, and away from direct sunlight. Properly sealed containers are essential to prevent moisture absorption, which could affect processing performance.
B2B Procurement Guide
When procuring Universal Brown Masterbatch, buyers should verify compatibility with their base polymer to avoid processing issues. Requesting technical datasheets and samples for testing is advisable to ensure color accuracy and performance. Suppliers often provide custom formulations to meet specific requirements, such as enhanced UV stability or food-grade compliance. Price negotiations should consider bulk purchase discounts, with typical reference prices ranging from $2.5 to $5.0 per kilogram.
