Generally better black pigment for plastic coloring, its choice basically according to products must meet the blackness. With very fine black pigment demanding automotive ABS senior PVC synthetic leather. Products, such as PE garbage bags, cables and pipes need to moderate level of blackness, so can choose smaller than surface, varieties of high structure carbon black.
2. Ultraviolet light stabilizers carbon black
Carbon black with high optical absorption, and thus can effectively prevent the plastic from the sunlight to generate light oxidation degradation. Black as the function of uv light stabilizer in plastic: effectively prevent radiation over a certain range of wavelength with the plastic surface; To convert light energy into heat energy; Intercept groups and anti aging effect.
3. Conductive carbon black
Carbon black added to any kind of polymer can reduce its volume resistivity. The lower performance depends on the carbon black particles and fill the quantity. Divide the original aggregate carbon black volatile, thus more energy is needed to make an aggregate transition from now on to aggregate. Volatile, therefore, carbon black, the increase will cause plastic resistivity of rise, lead to electrical.
