Founded in 2004 and located within the prominent Rubber Industrial Park of Boye County, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. has established itself as an authoritative leader in bulk material handling solutions. For over 22 years, our proprietary brand "Jinao" has represented unparalleled durability and precision in heavy-duty conveyor systems.
As a comprehensive, production-oriented enterprise, our operations encompass advanced polymer R&D, structural design, large-scale vulcanization, and professional technical field services. Our facility features automated compounding systems, high-pressure calenders, and continuous vulcanization lines to ensure consistent product properties across every square meter of skirting rubber and conveyor belt we produce.
Our commitment to excellence is supported by an independent chemical analysis lab and a state-of-the-art physics laboratory. We enforce a zero-tolerance policy for substandard materials, ensuring that only certified products leave our loading docks.
In bulk material handling, the transfer point is the most vulnerable zone for material spillage, dust emissions, and mechanical wear. Conveyor skirting rubber acts as a primary dynamic seal between the chute structure and the moving belt. Choosing the correct formulation, thickness, hardness, and mechanical profile is essential to maintaining system efficiency and extending belt life.
Our research and field data show that using an incorrect skirting compound can cause severe groove wear on the top cover of the conveyor belt. When skirting rubber is too hard (e.g., Shore A > 70) or contains abrasive materials, it acts as a cutting edge under high load. The "Jinao" brand skirting rubber is engineered with a dual-hardness profile or a specialized low-friction compound that seals dust while protecting the high-cost conveyor belt cover.
We synthesize skirting rubber using premium Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), and Polyurethane (PU) blends to optimize mechanical performance:
Modern high-capacity systems require more than simple flat rubber strips. Our dual-seal skirting systems utilize a primary sealing lip to contain bulk materials and a secondary flexible outer lip to capture fine dust particles. The secondary lip utilizes light pressure against the belt, forming an effective dust seal without increasing motor drive loads.
| Property Parameter | Standard Rubber Skirting | Premium NR/SBR Skirting | Polyurethane (PU) Skirting |
|---|---|---|---|
| Hardness (Shore A) | 65 ± 5 | 55 ± 5 (Soft Seal) | 80 ± 5 / 60 ± 5 (Dual Hardness) | Tensile Strength (MPa) | ≥ 8.0 | ≥ 15.0 | ≥ 25.0 |
| Elongation at Break (%) | ≥ 250 | ≥ 450 | ≥ 500 |
| DIN Abrasion Loss (mm³) | ≤ 200 | ≤ 120 | ≤ 40 |
| Working Temp Range (°C) | -25 to +70 | -40 to +80 | -30 to +90 |
Hebei Boao Rubber Technology operates modern manufacturing lines within a 30-acre campus. Our facilities utilize automated batching systems and precise calendering technology to ensure consistent product performance across all production runs.
Our quality control starts in the raw material warehouse. Every batch of natural rubber, carbon black, and chemical additives is inspected using carbon-black dispersion testing and rheometer analysis before compounding. Our calendering and shaping machines apply even pressure to prevent internal voids or weak spots that could fail under dynamic tension.
Industrial operations have unique requirements for conveyor system components. Our engineered skirting and conveyor products are customized to address these specific environmental challenges:
Sinter plant and blast furnace charging lines operate at high temperatures. Our heat-resistant EPDM skirting holds its shape at temperatures up to 180°C, containing hot fines and protecting the main belt from abrasive wear.
Underground coal handling requires fire safety compliance. Our skirting products feature flame-retardant, anti-static properties that meet global safety standards, reducing dust levels in high-risk zones.
Handling clinker and limestone creates highly abrasive dust. Our poly-urethane skirting seals transfer chutes tightly to contain fine particles, protecting bearings and moving parts from abrasive wear.
High-speed ship loading systems process large volumes of material under variable weather conditions. Our SBR/NR dual-lip skirting adapts to changing loads to prevent ocean spillage.
"Jinao" brand products are utilized by major mining groups, steel manufacturers, and construction projects, proving their reliability in heavy industrial operations.

For international procurement managers, quality certification and supply chain reliability are critical decision factors. Hebei Boao Rubber Technology maintains a comprehensive Quality Management System to guarantee performance standards across our product line.
Our operations are certified under international quality, environmental, and occupational safety frameworks, including:
We offer complete technical support packages to maximize conveyor system efficiency and reduce operational downtime:
Material sealing technology is evolving to support larger, faster, and more automated conveyor operations. Hebei Boao is actively developing next-generation skirting and sealing products to meet these demands:
Integrating indicator layers or electronic sensors within polyurethane seals to track real-time wear and alert maintenance teams before spillage occurs.
Formulating new rubber compounds that reduce VOC emissions during vulcanization and lower the total carbon footprint of bulk material handling systems.
Developing specialized rubber coatings with lower friction coefficients to maintain a tight seal while reducing energy consumption and belt cover wear.
