High temperature conveyor belt rubber
Characteristics
It can resist high temperature. The rubber compound used in the cover have been designed to avoid premature aging due to contact with any source of heat
It can be divided into four types according to working temperature range:
HRT-1 <=100° C, HRT-2<=125° C, HRT-3<=150° C, HRT-2<=175° C
Models
Mode1: Able to with stand the test temperature of less than 100° C, code S1
Mode2: Able to with stand the test temperature of less than 125° C, code S2
Mode3: Able to with stand the test temperature of less than 150° C, code S3
Mode4: Able to with stand the test temperature of less than 175° C, code S4

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: |
