Overview
Black PC Masterbatch is a pre-dispersed pigment concentrate designed specifically for polycarbonate (PC) resins. It ensures consistent coloration, high thermal stability, and UV resistance, addressing the stringent requirements of engineering plastics. The masterbatch is formulated to withstand PC processing temperatures (280-320°C) without degradation, making it suitable for injection molding, extrusion, and blow molding. Its uniform dispersion properties eliminate streaking or uneven coloring in finished products.
Physical and Chemical Properties
Black PC Masterbatch exhibits excellent compatibility with polycarbonate, ensuring minimal impact on the resin's mechanical properties. Its high pigment loading (typically 20-40%) allows for efficient coloring at low dosage rates (1-5%). The product's thermal stability prevents discoloration or decomposition during high-temperature processing. It also offers UV resistance, making it suitable for outdoor applications where colorfastness is critical.
Main Applications
This masterbatch is widely used in automotive components such as headlight housings, interior trim, and connectors due to its durability and aesthetic consistency. In electronics, it colors laptop casings, mobile phone frames, and optical lenses. Consumer goods like kitchenware, eyewear, and transparent tinted panels also benefit from its uniform dispersion and resistance to fading. Its versatility extends to medical devices, where non-toxicity and compliance with regulatory standards are essential.
Safety and Storage
Black PC Masterbatch is generally safe when handled properly, though dust inhalation should be avoided. Use standard PPE (gloves, masks) during processing to minimize exposure. Store the product in sealed, moisture-proof containers at temperatures below 30°C. Prolonged exposure to humidity can affect dispersion performance, so ensure packaging integrity is maintained during transportation and storage.
B2B Procurement Guide
When sourcing Black PC Masterbatch, prioritize suppliers with proven expertise in PC-compatible colorants. Request technical data sheets (TDS) and material safety data sheets (MSDS) to verify compliance with industry standards. Evaluate samples for color consistency, thermal stability, and dispersion quality under your specific processing conditions. Bulk pricing discounts are commonly available for orders exceeding 1 ton, but confirm lead times and minimum order quantities (MOQs) in advance.
