The carcass of the product  selects cotton vanvas or EP canvas as skeleton material.Cover rubber and cushion rubber is styrene-butadiene rubber or chlorobutadiene that has god heat-resistant.The product can work under the temperature of 120^oC.Heat-resistant conveyor belt widely used in industries of metallurgy,cement,coking,steel,and etc.
1.Specification as same as common conveyor belt
2.Heat-proof conveyor belts are categorized in three models
Model I:Able to withstand the test temperature of less than 100 ℃,codes T1
Model II: Able to withstand the test temperature of less than 125 ℃,codes T2
Model III: Able to withstand the test temperature of less than 175 ℃,codes T3
Model IV: Able to withstand the test temperature of less than 200 ℃,codes T4
The physical performance of cover rubber after heat-proof test comform to the specification in the table.
