What is of carbon black N339
Carbon black N339 with high abrasion furnace grade features a high surface, and high structure that offers excellent processing properties. Usually used black N339 in tire tread, tire casing, tire beads, hard tires, molded products, and also conveyor belts which require high abrasion resistance and perfect dynamic properties such as tread wear and hysteresis.
As a result, Carbon N339 has nearly the same reinforcing intensity, and wear resistance, and it has tear resistance like N220.
Compared to N330, N339 has a higher structure , and smaller particles. As well as The N339 compound has better abrasion and resistance than those of high abrasion furnace black-high structures such as N347.
Usage of carbon N339
The Carbon black N339 is usually used for Premium passenger tire tread compounds and heavy lorry tires. And used For Motor mounts and Solid tires, at last its used at conveyor belts, and also rubber products requires high wear resistance.

A: Carbon Black N339 is a high-structure furnace carbon black grade created through controlled incomplete combustion of hydrocarbon feedstocks. It is designed for use in rubber applications requiring strong wear resistance and balanced reinforcement.
A: Typical values include iodine adsorption around 90 g/kg, oil (DBP) absorption around 120 cm³/100 g, ash content no more than 0.45 %, heating loss at 125 °C ≤ 1.0 %, pour density approximately 345 kg/m³, and fines content under ~7%.
A: N339 is commonly used in passenger- and truck-tire tread rubber compounds, conveyor belts, hoses and industrial rubber goods where high wear performance and tear resistance are required.
