Product Description
Heat resistant conveyor belt is suitable for transporting high temperature materials, such as sintering ore, burning carbon, cement clinker and hot casting etc. According to conveying capacity lost caused by the damage of conveyor belt and heat resistant grades, it will use EPDM or SBR as the cover and high strength, high penetration polyester or cotton canvas as strength ply. The heat resistant glass fabric can be laid between the cover and skeleton to improve the service life of the belt. It can be made as endless type according to the request by customers.
Specification
After testing the heat resistant for cover of the belt, the physical and mechanical properties fit the standard in the sheet below:
