Import Carbon Black For Plastic Masterbatch/Pigment — Buy in Bulk from Supplier in China

Carbon black for plastic masterbatch and pigment from China Rubber Group Carbon Black Research and Design Institute is a finely engineered additive designed to deliver deep, consistent black coloration and UV resistance in plastic formulations. The product exhibits strong tinting strength and excellent dispersibility, ensuring uniform mixing in polymer matrices without agglomeration. Variants are tailored to specific degrees of blackness, supporting applications where precise color control is critical, such as automotive trim, packaging, and consumer goods.

The material is derived from controlled combustion processes, producing a high-purity carbon with a low volatile content typical for pigment-grade carbon black. Its particle size distribution and surface chemistry are optimized for compatibility with polyolefins, PVC, and engineering plastics, reducing processing defects like streaking or speckling. Industry standards for such carbon black often include a surface area range of 25 - 1500 m²/g (typical), with a pH of 7 - 10 (standard) to minimize corrosion in processing equipment.

This carbon black is primarily sourced by manufacturers of plastic masterbatches, where it serves as both a coloring agent and a performance enhancer, improving mechanical properties such as tensile strength and weatherability. Buyers typically confirm compatibility with their base resins and processing conditions, as well as packaging options like 25 kg paper bags or bulk delivery. Trade terms such as FOB or CIF are negotiable, with MOQ and lead times varying by order size and destination.

China Rubber Group Carbon Black Research and Design Institute is based in Zigong, Sichuan, with its registered address at No.568, Huixing Road, Huidong District. The institute operates as an imported-tier supplier, indicating a focus on specialized or high-value carbon black products for industrial applications. Its profile does not list active response metrics, so buyers should verify current lead times and availability directly.

The supplier’s description emphasizes its role in providing carbon black tailored for plastic masterbatch and pigment use, with a technical focus on tinting strength and dispersibility. While the listing does not specify certifications like ISO or SGS, these are common for such products in the industry, and buyers are advised to request documentation. The supplier’s specialization in carbon black suggests a depth of expertise in this niche, particularly for plastic manufacturing.
