  • brominated compounds Due to the vulcanization of the rubber compound, the conveyor belt experiences the required elastic properties. In addition, flame retardants are usually added to the two cover plates to meet flame and fire protection requirements. So far, brominated compounds have been used both for steel cord conveyor belts and for fabric conveyor belts. These guaranteed the use of the conveyor system even in very different climatic zones. In particular for steel cord conveyor belts when used in countries with in some cases very low temperatures, cold-flexible rubbers such as, for example, butadiene rubber or styrene-butadiene rubber are used, which have been rendered flame-retardant with brominated compounds. Even in small quantities, brominated compounds are good flame-retardant, but are considered to be so-called PBT substance (persistent, bioaccumulating, toxic) and may therefore according to the latest
