Heat resistant EP conveyor belt (HR EP conveyor belt/temperature resistant conveyor belt) is suitable for transporting high temperature materials, 90 degree/100 degree/150 degree/175℃/200℃+, such as sintering ore, hot coke, cement clinker, hot casting, fertilizer materials, etc. The belts are used in steel plant, fertilizer plant, phosphate fertilizer factory. According to heat resistant grade of different working conditions, we use EPDM or SBR as cover rubber and use high-strength EP or cotton canvas as tension element.
