Import Carbon Black — Buy in Bulk from Supplier in China

Worldspread Intl. (Hk) Limited offers carbon black produced in China for industrial use. The material is noted for strong pigmentation and reinforcing properties, meeting ISO and SGS standards. While the listing does not enumerate specific grades, the product is characterised by high iodine absorption and excellent DBP absorption. The carbon black is supplied in bulk quantities suitable for large‑scale manufacturing.

Typical carbon blacks of this class exhibit an iodine number between 115 and 135 mg g‑1 and a DBP absorption of 150 - 180 ml 100 g‑1. Particle size (D90) usually lies in the 180‑250 nm range, providing good dispersion in rubber and polymer matrices. Reinforcing index values are commonly 90‑115, delivering enhanced tensile strength in tyre compounds. Oil absorption is generally 110‑140 ml 100 g‑1, which influences mixing viscosity and processing temperature.

Main buyers are tyre manufacturers, automotive component producers and coating formulators requiring consistent colour and durability. Worldspread allows flexible minimum order quantities and can ship on FOB or CIF terms from Chinese ports such as Shanghai or Qingdao. The product is packed in sealed bulk bags or 20 kg bags to avoid moisture ingress during transit. Prospective purchasers should request the exact grade data sheet, certification copies and confirm payment and delivery schedules with the supplier.
