Overview
Superior Solid Black Granules are premium-grade granular materials primarily composed of carbon-based compounds with additives for specific performance characteristics. These granules are engineered for consistent quality, offering reliable performance in various industrial processes. The manufacturing process involves precise control of particle size and composition to ensure uniform properties. These granules are particularly valued in industries requiring consistent coloration and material properties, with quality standards typically exceeding those of standard black pigments or fillers.
Physical and Chemical Properties
The granules exhibit excellent thermal stability, maintaining their structural integrity at processing temperatures common in plastic and rubber manufacturing. Their uniform particle size distribution ensures consistent dispersion in host materials, a critical factor for quality end products. Chemically, these granules are inert under normal conditions but may oxidize at elevated temperatures. The exact properties vary by formulation, with some grades offering enhanced UV resistance or electrical conductivity for specialized applications.
Main Applications
These granules serve as essential components in plastic product manufacturing, particularly for items requiring deep, consistent black coloration. They're widely used in injection molding and extrusion processes for automotive parts, consumer goods, and packaging materials. In the rubber industry, they function as both colorants and reinforcing agents. Additional applications include use in masterbatch production, where they provide concentrated color for subsequent dilution, and in specialty coatings requiring durable, fade-resistant black pigmentation.
Safety and Storage
While generally stable, these granules require proper handling to prevent dust formation. Facilities should employ local exhaust ventilation during large-scale handling, and personnel should use appropriate personal protective equipment, especially when handling powdered forms that may occur during transport. Storage recommendations include keeping containers tightly sealed in dry conditions below 30°C. Bulk storage should avoid direct contact with floors or walls to prevent moisture absorption. Shelf life typically exceeds 12 months when stored properly.
B2B Procurement Guide
Industrial buyers should specify required parameters including particle size distribution (typically 0.5-3mm), melt flow index compatibility, and thermal stability requirements. Certificates of analysis for each batch are recommended to ensure consistency. Consider minimum order quantities, which commonly range from 500kg for specialty formulations to multi-ton shipments for standard grades. Evaluate suppliers based on their quality control processes, technical support capabilities, and ability to provide customized formulations if required.
