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
