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 EDPM 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 cllients' requirement.
The physical and mechanical properties of the heat resistant covering layer after tested should be in accordance with the following table: | |||||

| Change the range | |||||
| Hardness | Draw the intensity | 20 | 20 | 20 | 20 |
| Maximum after wearing out | 85 | ||||
| Draw the intensity | The minimum value Mpa after wearing out | 12 | 10 | 5 | 5 |
| Performance rate of change /% | -25 | -30 | -40 | -40 | |
| Break person who extend | Performance rate of change /% | -50 | -50 | -55 | -55 |
| After aging rate of change /% | 200 | 200 | 180 | 180 | |
The heat resistance conveyor belt physical property of the cover rubber after heat test shall conform to the values specified in the table.
