Engineered for high tension, maximum wear resilience, and specialized operational demands.
A trusted manufacturing hub driving bulk material transport technology globally.
Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province. As a professional manufacturer in China that integrates product development, research, design, manufacturing, and business services for conveyor belts and conveyor machinery accessories, we have passed the international quality management system certification in one go. The company has multiple advanced equipment production lines for rolling, forming, vulcanization, and rubber testing (from raw materials to finished products).
Our infrastructure guarantees that every batch of EP Fabric Conveyor Belting, Patterned Belts, and Steel Cord variants satisfies heavy mining, mineral storage, and power generation specifications. Through systematic mechanical processing and testing, we maintain high elongation tolerances, excellent rubber-to-fabric adhesion, and resistance to cover wear.
An in-depth analysis of structural integrity, engineering parameters, and material advantages.
EP fabric, commonly referred to as Polyester-Nylon fabric, consists of polyester yarns in the warp (longitudinal direction) and nylon yarns in the weft (transverse direction). This specific synthetic fiber combination provides distinct physical characteristics:
| Metric Parameter | EP (Polyester-Nylon) | NN (Nylon-Nylon) | Steel Cord Core |
|---|---|---|---|
| Tensile Range (N/mm) | 100 to 630 per ply (EP100 - EP630) | 100 to 500 per ply (NN100 - NN500) | ST500 to ST5400+ |
| Elongation at Rated Tension | Extremely Low (≤ 1.5%) | Moderate (2.0% - 3.5%) | Negligible (≤ 0.25%) |
| Impact Resistance | High (Dampens point loads) | Very High (Flexible matrix) | Excellent (Requires rip protection) |
| Troughability Factor | Excellent (30° - 45° idlers) | Excellent | Requires specialized transitions |
The EP fabric carcass must be shielded from environmental factors and the abrasive action of transported materials. We formulate customized rubber covers that comply with various international standards, including DIN 22102, AS 1332, and ISO 10247:
Multi-roll precision calendering systems ensure consistent rubber penetration into the EP fabric pores, preventing delamination under severe impact load.
Simulating hundreds of thousands of cycles around drive and tail pulleys to verify core stability and prevent cover cracking at the seams.
Independent physical & chemical laboratories inspect incoming raw materials, checking polymer compound consistency, density, and tensile strength before mixing.
Driving core operations across heavy industrial sectors on a global scale.
Modern steel plants require conveyor belts that can handle high heat, abrasive materials, and continuous operation. EP and heat-resistant steel wire core belts transport heavy raw materials from blast furnaces to sintering stations.
Underground mining and enclosed thermal power conveyors must comply with strict fire prevention standards. Our flame-retardant EP rubber belts are designed to self-extinguish and prevent flame propagation.
Our dedicated laboratory performs systematic material characterization to ensure consistent product performance.
Measures the interface adhesion strength between rubber covers and EP fabric plies to prevent delamination.
Tests the adhesion strength between steel wires and rubber in high-strength steel cord belts.
Simulates cyclic bending stress under tension to determine the long-term fatigue limit of the carcass.
Measures cover rubber volume loss (in mm³) to ensure compliance with wear resistance standards.
Our chemical analysis laboratories monitor raw materials from procurement to product delivery. We use dedicated feeding equipment, calendering & shaping machinery, and automated vulcanizing presses to maintain consistent quality across all production batches. Unqualified raw materials are rejected, and finished products undergo testing before leaving the factory.

Developing next-generation conveying technologies to support industrial decarbonization and smart monitoring.
Reducing volatile organic compound (VOC) emissions during hot vulcanization. We are testing plant-derived process oils and carbon black substitutes to lower the carbon footprint of rubber compounding.
Developing EP and steel cord belts with embedded inductive loops. These loops communicate with scanner heads to identify early-stage tears and trigger automatic emergency shutdowns, preventing catastrophic failures.
Developing backing rubber compounds with reduced visco-elastic indentation loss. ULRR covers reduce friction between the belt and rollers, lowering power consumption on long-distance conveyors by up to 15%.
End-to-end support to optimize conveyor operation and extend belt service life.
Detailed system evaluation, structural calculations, and selection of the appropriate EP ply rating and cover grade for your application.
Supplying high-bond splice kits and technical guidance for hot vulcanization or mechanical fastening to maximize joint efficiency.
Ultrasonic cover thickness measurements and regular inspections of tracking and alignment to catch wear early and prevent downtime.
