Silica has a wide range of uses, and different products have different uses. Used as a good reinforcing agent for synthetic rubber, its reinforcing performance is second only to carbon black, and even better than carbon black after ultra-fine and proper surface treatment.
White carbon black is added to the resin to improve the moisture-proof and insulating properties of the resin. Filling in plastic products can increase slip resistance and oil resistance. Filled with silicone resin, it can be made into plastic with resistance above 200℃.
White carbon black can be used as a filler in polyethylene, polypropylene, polybutene, epoxy resin and other plastics, which can improve the elastic strength and wear resistance of the plastic, as well as the thermal stability of hardness. The use of white carbon in cables can also improve the electrical insulation of cables. For example, methyl vinyl silicone rubber high-voltage wires should use fumed white carbon black or high-quality precipitated white carbon black. It is often difficult to separate between the two layers of plastic film, and the bag opening is difficult to open when bagging, so white carbon black is a very popular opening agent.
Due to the high heat of carbon black, white carbon black is also tended to be added to automobile tires used on highways abroad. At present, the domestic and foreign markets have increasingly diversified requirements for bicycle tires. For example, new fancy varieties such as tire bead colorization and flashing rings are produced with white carbon black instead of carbon black.
