Carbon Black N234, China Carbon Black Manufacturer & Supplier
Beilum Carbon black N234 is used in the tread compounds of high speed tire and high performance rubber products.
Carbon Black N234
Other Name:Intermediate Super Abrasion Furnace Black-high structure (New technology); ISAF-HS (New technology)
N234, compared to other grades of N220 series, has higher structure, higher abrasion.
Usage and Function:
The compound filled with Carbon Black N234 has better abrasion than those with N220, N242 and N339.
Its abrasion is about 10% higher than those of compounds with N220.
Especially in the rigorous conditions, it shows very good abrasion performance. The process performance of the N234 compounds is good too.
The surface is smooth, suitable for various compounds.
The deficiency of the N234 compounds is its high heat-up and high hysteresis loss.
Application:
N234 is used in the tread compounds of high speed tire and high performance rubber products.
