This unique property makes N990 ideal for applications where low compression set, high elongation, and superior dispersion are required.

Key Specifications of Carbon Black N990:

• Iodine Adsorption Number: 10-14 g/kg (ASTM D1510)

• Oil Absorption Number: 37-44 cm³/100g (ASTM D2414)

• Ash Content: 0.1-0.4% (ASTM D1509)

• Heating Loss: 0.02-0.1% (ASTM D1506)

• Sieve Residue (#35): Max 0.1% (ASTM D1514)

• Sieve Residue (#325): 3-15 ppm (ASTM D1514)

• pH: 6.5-9 (ASTM D1512)

• Packaging: Available in 25kg bags or 1MT Jumbo Bags.

These specifications make Carbon Black N990 a highly versatile material, suitable for various industrial applications.
