N339 Carbon Black For Tyre, Rubber, Plastic, Painting

Other Name: High Abrasion Furnace Black-high Structure (New technology);HAF-HS(New technology)   Physical & Chemical Properties:  Its iodine adsorption value is 90 g/kg, and DBP adsorption is 120cm3/100g. Compared to N330, N339 has higher structure, smaller particles. The N339 compound has better abrasion and crack resistance than those of high abrasion furnace black –high structure (old technology) such as N347.   Application:N339 is used in the tread compounds of passenger tire and truck tire, coating compounds of conveyor belt, hose and industrial compounds with high abrasion properties.       Performance Features   •             Moderately high reinforcement   •             Good abrasion resistance   •             High modulus      Typical Applications   •             Passenger and truck tire treads   •             Carcass   •             Tire sidewall   •             Conveyor belt covers Test Items Unit Index Iodine Adsorption Number g/kg 90±5 Oil absorption Number(OAN) 10-5m3/kg 120±5 Crushed OAN (COAN) 10-5m3/kg 94-104 CTAB absorption surface Area-N2 103m2/kg 87-99 STSA 103m2/kg 88±5 N2SA 103m2/kg 86-96 Tint Test, Reflectance From ITRB % 106-116 Moisture, Bulk& Bag (as shipped) % <=2.0 Ash content % <=2.00.5 45um Sieve residue % <=2.00.05 Impurity / None Fines/Attrition % <=2.08 (Note l)(25g,No.120 US Std Sieve)     Pour density kg/m3 345±40 300% stretching stress (SRB7#) Mpa 0.6±1.0
