Compared with carbon black, which properties of silica reinforced rubber materials are better, and why?

A really good charcoal black has a hairy look.

In tires, compared with carbon black, white carbon black can reduce rolling resistance, which is to save fuel. In addition, carbon black reinforced tires at high speed in low heat generation. As for the disadvantage? It doesn't wear well.

Carbon black, also known as carbon black, is an amorphous form of carbon. Light, loose and very fine black powder, with a very large surface area, ranging from 10~3000m2/g, is the product of carbon containing substances (coal, natural gas, heavy oil, fuel oil, etc.) under the condition of insufficient air through incomplete combustion or thermal decomposition. The proportion of 1.8 2.1. Made of natural gas called "gas black", made of oil called "lamp black", made of acetylene called "acetylene black". In addition, there are "trough black", "furnace black". According to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear resistant carbon black" and so on. It can be used as a black dye for making Chinese inks, inks, paints, etc. It is also used as a reinforcing agent for rubber.
