Benzene, an organic compound, is the simplest aromatic hydrocarbon with a chemical formula of C6H6. At room temperature, it is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity and a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing a hydrogen atom from the benzene ring is called phenyl, which is represented by Ph, so the chemical formula of benzene can also be written as PhH. Benzene is a basic petrochemical raw material, and its output and production technology are one of the symbols of a country's petrochemical development level.
On October 27, 2017, the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer was preliminarily sorted out for reference, and benzene was included in the list of Class I carcinogens.

The benzene ring is the structure of the benzene molecule. It is a plane regular hexagon, each vertex is a carbon atom, and each carbon atom is combined with a hydrogen atom. The carbon-carbon bond in the benzene ring is a unique bond between single and double bonds, with a bond angle of 120° and a bond length of 1.40Å

Heat resistant conveyor belt is mainly used to transport high-temperature materials, such as sintering ore, hot coke, clinker, hot casting and so on. According to the manifestation of the heat-resistant belt breakage, until to lose transportation ability and the heat-resistant grading, we use EPDM or SBR as the covering layer rubber, and high modulus low shrinkage polyester or cotton canvas as the strong layer. It can use the heat-resistant woven glass fabric between the cover rubber and the layers, so as to improve the working life of the heat-resistant conveyor belt. We can make it into endless conveyor belt as per clients' requirement.
