Photoluminescent Gravel of carbon black

photoluminescent powder is generally used for those who do not need a strong coloring power , high covering power or UV protection garbage bag production . Colors tend to gray-blue , cheap , and relatively easy dispersion , so that only equipped with a single or twin screw extruder for masterbatch small firms would choose this carbon black. HAF carbon black, SRF carbon black particles is half the size of particles , but it is two times the intensity of coloration . Brownish red , and its UV protection is stronger than SRF carbon black , and the cost is lower than the P carbon black. It has good covering power , can be applied in many ways. P carbon black suitable for UV applications as well as the food industry, reddish blue.masterbatch production JET carbon black with the most satisfactory color shading , dark , shiny black. It is the smallest particles , but not easy dispersion . Only those manufacturers with high- shear mixer in order to obtain the degree of consistency when using the JET carbon black dispersion . It is also the most expensive of ordinary carbon black . Cost comparison shows that the more expensive the production of masterbatch get better results than can be economically cheaper masterbatch.
