Import Carbon Black St213b — Buy in wholesale FOB from Supplier in China

Carbon Black St213b is a regular color gas-processed pigment, supplied in both powder and bead forms to accommodate different handling systems. The grade is formulated for industrial applications where durability and thermal stability are critical, such as in plastics and coatings. Produced by Shanxi Starwin Science & Technology Co., Ltd. in Taiyuan, Shanxi, this carbon black achieves a typical iodine adsorption of 230 to 250 mg/g and a DBP absorption of 100 to 110 cm³/100g, delivering high tinting strength with controlled structure for balanced performance.

Gas blacks like St213b are known for their fine particle size, with a typical range of 18 to 22 nm, which contributes to deep jetness in inks and coatings. The grade’s low volatile organic compound content ensures compliance with environmental regulations, making it suitable for water-based and solvent-based systems alike. Standard industry specifications for this category include a pH of 6 to 8 and a heating loss of less than 2%, with sulphur content typically below 1% to minimise odour and corrosion in the final product.

This carbon black is widely used in the automotive and construction sectors, particularly in the production of paints, plastics, and rubber goods where colour consistency and resistance to UV degradation are essential. The supplier offers bulk supply options, with packaging in 20 kg or 25 kg bags, and recommends confirming the form (powder or bead) to match your production line’s requirements. Buyers should request a certificate of analysis to verify the iodine adsorption and thermal stability, as these properties influence the material’s performance in high-temperature applications.

Shanxi Starwin Science & Technology Co., Ltd. is based in Wucheng Street, Xiaodian District, Taiyuan, Shanxi Province, China, a region known for its chemical manufacturing infrastructure. The company holds a harbor trust tier classification, which signifies a verified business profile, though its current response rate to enquiries is not available. The supplier specialises in gas and furnace carbon blacks, catering to industries such as coatings, plastics, and inks.
