Heat-resistant conveyor belts are mainly used to convey high-temperature materials, such as sinter, hot coke, cement clinker, hot castings, etc. According to the main performance of resistance to tropical damage and loss of conveying capacity and different heat resistance levels, ethylene propylene diene or styrene butadiene rubber are used as covering rubber; High strength high permeability polyester canvas or cotton canvas for the strength layer. Pyrex glass cloth can be arranged between the covering glue and the skeleton layer to improve the service life of the tropical resistance. According to user requirements, can be made into a ring belt.|
