In a very high temperature working condition, normal conveyor belt will not last very long since its maximum operating temperature is only about 80°C. In such case, a heat resistance cover rubber grade must be used.
Heat resistance grade conveyor belt is made of special compound consisting of synthetic rubber that can withstand high heat. However, in order to use heat resistance conveyor belt, the following information must be considered: the working temperature, the type of conveying materials, the heat accumulation, and the conveying distance.
The following tables indicate the specifications of the heat resistance conveyor belts that our company Bach Tung JSC provide:
