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