Why does rubber burn black smoke?
Natural rubber is the structure of isoprene polymers, itself contains a large number of carbon elements
Rubber is filled with black carbon, which is used to dye, but to increase hardness, burning black smoke.
So, when rubber burns, it does not burn completely. There are many black carbon, which form black smoke
Synthetic rubber inside will be artificially adding carbon black, to reinforce and improve the wear resistance and reduce the cost. For example, many synthetic rubber: butadiene rubber, chloroprene rubber, styrene butadiene rubber must be reinforced in order to achieve the use of carbon black, tensile strength, elongation and wear ideal.
