Henan Watering Industrial Co., Ltd. supplies a range of carbon black grades N330, N220, N550 and N660 designed for the tyre industry. The product meets GB3778‑2011 test results with a Standard Iodine Absorption Number of 82 ± 5 g/kg (target 80 g/kg). Oil Absorption Number is recorded at 102 ± 5 × 10⁻⁵ m³/kg (target 99 × 10⁻⁵ m³/kg) and Crushed OAN at 88 ± 5 × 10⁻⁵ m³/kg (target 91). Other measured parameters include a Tint Test reflectance of 104 ± 8 % (target 100 %) and a Pour Density of 380 ± 40 kg/m³.
In tyre compounds N330 provides a balance of reinforcement and processing ease, while N220 offers higher tensile strength for high‑performance tyres. N550 and N660 are high‑structure grades that increase abrasion resistance and reduce rolling resistance, typical of modern passenger and truck tyres. Industry standards generally place iodine absorption for these grades between 70 and 95 g/kg and oil absorption between 90 and 110 × 10⁻⁵ m³/kg, matching the values reported by the supplier. Typical bulk density for tyre‑grade carbon black ranges from 350 to 400 kg/m³, and ash content is usually below 0.6 %.
The material is sold in bulk, commonly packed in jumbo or paper bags, and is purchased by tyre manufacturers and rubber compounders worldwide. Importers should request the supplier’s test certificates and confirm the minimum order quantity, lead time and chosen Incoterms before placing an order. Payment terms and shipping details are negotiated directly with Henan Watering Industrial Co., Ltd. to suit the buyer’s logistics requirements.
