High Temperature Resistant Conveyor Belt For Mining Coal Cement Bulk Material Conveyor System
The heat resistant rubber conveyor belt consists of three key integrated parts, optimized for high-temperature resistance and mechanical strength:
• High-Temperature Resistant Rubber Covers (Top & Bottom): The outer protective layer made of special heat-resistant rubber compounds (mainly EPDM, Neoprene/CR, butyl rubber, or blended heat-resistant rubber), which directly contacts high-temperature materials and resists heat penetration, abrasion, and thermal aging.
• Reinforcing Carcass Layer: High-strength tensile core, generally divided into nylon canvas (NN) for medium heat resistance and steel cord (ST) for heavy-duty, ultra-high temperature and long-distance conveying; the carcass features low thermal expansion and high tensile strength to maintain belt stability under heat.
• Adhesive Rubber Layer: Special high-temperature resistant bonding rubber that firmly connects the rubber cover and carcass, preventing delamination, bubbling, or separation caused by high temperature, ensuring overall structural integrity.
