INTRODUTION
Carbon Black N774 is also called Semi-reinforcing furnace-high modulus black of non-staining (SRF-HMNS). The compound filled with N774 has excellent processing property, and N774 can be used with high load. Its compound has high elongation, low heat-up, high elasticity and good aging-resistance.
APPLICATION
Compared with Semi-reinforcing furnace-low modulus black of non-staining (SRF-LMNS) such as N762 and N772, N774 has higher structure and higher light transmittance of toluene extract for about 95%, although they have the same surface area. Its main characteristics are low solvent extract and non-polluting. It's mainly used incompounds of tire cord, sidewall. inner tube, rubber hose, belt, etc.
