Rubber Carbon Black of N660
N660 is a kind of universal carbon black with higher structure and fine particle and easily dispersed in the rubber. It has higher vulcanizate tensile strength, tear strength and extension stress, small deformation, low heat and good flexibility. It is widely used due to the high return elasticity of semi-reinforcing furnace black and bending resistance of fine particle furnace black. Its main technical indicators are as follows:
