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.
