The "EP" designation refers to a carcass constructed from plies of high-tenacity fabric woven with Polyester (E, for ‘Ethylene terephthalate’) warp threads and Polyamide (N, for ‘Nylon’) weft threads. The polyester provides high modulus and low elongation, ensuring the conveyor belt remains dimensionally stable under load, while the polyamide (nylon) contributes superior impact and tear resistance. Consequently, the EP Conveyor Belt offers a superb balance of properties, making it one of the most prevalent types for medium-to-long distance, high-strength applications in mining conveyor belt systems, widely used for transporting raw coal and various ores.
