Adopting all-cotton canvas and polyester canvas as framework materials of the belt core and butadiene styrene rubber or butyl chloride rubber with excellent heat resistance as cover rubber or buffer rubber, the product can be normally used at a temperature below 120 ℃, can convey materials which have a temperature below 120 ℃, and is widely applicable to such industries as cement, coking, metallurgy, iron and steel, etc.
Specification the same as common conveyor belt
Heat-resistance conveyor belt can be classified into three models:
Model: Capable of resisting experimental temperature no more than 100 ℃, in code of T1.
ModelⅡ: Capable of resisting experimental temperature no more than 125 ℃, in code of T2.
ModelⅢ: Capable of resisting experimental temperature no more than 150 ℃, in code of T3.
ModelⅣ: Capable of resisting experimental temperature no more than 175 ℃, in code of T4.
