Founded in 2004, Hebei Boao Rubber Technology Co., Ltd. (brand "Jinao") is a vanguard in the research, design, manufacturing, and servicing of high-performance conveyor belts and structural conveyor machinery accessories. Operating from Boye County's Rubber Industrial Park in Baoding, Hebei, our modernized lines deliver world-class belt plies with unparalleled carcass integrity.
Engineered to handle extreme loads, aggressive chemicals, severe abrasion, and temperature fluctuations.
Polyester (EP) conveyor belts are the backbone of modern heavy bulk material transport. Compounded from a synthetic matrix of polyester warp fibers and polyamide (nylon) weft fibers, EP carcass belts exhibit a exceptionally high modulus of elasticity, minimal elongation under working tension, and remarkable resistance to biological decay, mechanical impact, and water degradation. In terms of global mining, logistics, and metallurgical operations, selecting the right EP grade is critical to reducing structural downtime and minimizing energy consumption.
SEO Insight & Information Gain: While standard marketplace catalogs simply list sizes, engineers require precise structural performance values. EP fabric belts offer lower elongation compared to Nylon (NN) belts (typically 1.5% at nominal load for EP vs. 2.5% for NN). This directly translates to shorter take-up strokes, saving substantial infrastructure costs on long-distance conveyor runs.
Unlike cotton or nylon-only composites, polyester does not lose tensile strength when damp. This high-moisture immunity makes EP conveyor belts ideal for wet screening, port offloading, coal washing plants, and coastal aggregates. Additionally, the cross-weave nylon fibers in the weft directional plane provide excellent troughability and superior impact absorption, shielding the internal carcass from rupture when handling jagged materials like run-of-mine ore, granite, and metallurgical coke.
| Property Parameter | EP (Polyester/Polyamide) | NN (Nylon/Nylon) | CC (Cotton/Cotton) |
|---|---|---|---|
| Elastic Elongation (%) | 1.5 - 2.0 (Low) | 2.5 - 3.0 (Medium) | 4.0 - 5.0 (High) |
| Moisture Sensitivity | Immune (Maintains Strength) | Slight Loss (1-3% Strength reduction) | High Loss & Rot Vulnerable |
| Troughability Ratio | Excellent (Good cross-flex) | Excellent | Poor to Moderate |
| Cost Efficiency | Optimal lifecycle value | Standard | Low initial / High wear-replacement |
Our uncompromising quality assurance program keeps heavy-industry operations running reliably 24/7/365.
At Hebei Boao Rubber Technology, we operate internal chemical analysis rooms and physics testing labs. No raw rubber batch or fabric roll is processed without passing comprehensive compound validation. Unqualified items are rejected immediately at our receiving docks.
Using dynamic fatigue testers, abrasion testers, and steel cord pull-out rigs, we simulate thousands of operational hours. We measure the belt's adhesion strength between plies, absolute resistance to surface tearing, and longitudinal wear limits before shipping.
Back by robust logistics and comprehensive after-sales technical support, Boao belts are deployed across major industrial zones worldwide. Our belts operate in heavy-duty sectors like metallurgy, coal extraction, cement, and thermal power generation.

Our Boye County plant features an automated mixing center, high-precision multi-roll calendering systems, and heavy vulcanizing presses. Our modern facilities produce high-strength EP fabric conveyor belts, steel cord belts, patterned profiling belts, and specialized dynamic accessories. By controlling the formulation chemistry and vulcanization parameters, we guarantee our belts perform reliably and minimize longitudinal tearing under load.
Different industrial operations require specific elastomer formulations. Mining operations need high impact resistance, whereas cement plants require heat-resistant compounds. Boao custom-engineers EP conveyor solutions to match these varying environments.
Hard rock, minerals, and mineral concentrates demand belts with high impact resistance and structural longevity. Our dynamic EP multi-ply fabric belts absorb shock loads at transfer points, while our cover compounds resist cutting, gouging, and scaling.
Coal transport requires strict safety compliance, including flame retardant cover systems. Our anti-static, fire-resistant EP conveyor belts prevent fires and combustion in dust-prone underground mines and power generation silos.

Sourcing a premium conveyor belt is only the first step. Proper installation and maintenance are essential for maximizing the service life of your investment. Improper splicing or tensioning can lead to rapid premature wear, tracking issues, and carcass separation.
To match different working environments, we support cold vulcanizing joints, hot vulcanizing splicing, and mechanical fasteners. Hot vulcanizing provides up to 90%+ joint strength efficiency, ensuring reliability for high-tension systems.
We offer detailed technical plans for planned replacements, regular inspections, and belt surface repair. Regular monitoring of the cover thickness and edge wear helps prevent unexpected belt tracking failures.
Our factory supplies high-quality vulcanizing rubber strips, tie gum, and repair patches. Our technical support team assists operators in scheduling repairs during planned maintenance shutdowns.
Our products meet key international standards, ensuring seamless integration into global supply chains.
Hebei Boao Rubber Technology operates under a comprehensive quality management system. Our factory certifications include:
Quality System ISO
Factory Testing Approval
Enterprise Integrity License
Technical Compliance
As heavy industry shifts toward digitalization and carbon-reduction targets, conveyor systems are evolving. Hebei Boao Rubber Technology is actively developing two key areas: smart real-time monitoring and eco-friendly compounding.
To minimize downtime, we are developing EP conveyor belts with embedded RFID chips and magnetic sensor arrays. These systems monitor wear rates and detect longitudinal rips automatically, signaling system shutdowns before critical failure.
Over long distances, conveyor systems consume significant electrical energy. Our LRR rubber compounds reduce energy consumption by up to 15% by reducing cover deformation over idlers, directly lowering operational costs.
