Features and application:The heat resistant conveyor belts consist of heat resistant rubber cover and fabric core with multi-layers,widely used in metallurgy,building materials,coking,casting and chenmical industry.

It can be divided int 4 grades according to the testing temperature.

T1-the testing temperature <100℃

T2-the testing temperature <125℃

T3-the testing temperature <150℃

T4-the testing temperature <175℃

The standards:GB/T 20021-2005《Fabric core resistant conveyor blets
