Engineered to survive extreme wear, aggressive abrasion, high temperatures, and chemical exposure across raw bulk materials terminals globally.
Founded in 2004, Hebei Boao Rubber Technology Co., Ltd. (operating the premier industrial brand Jinao®) occupies a massive state-of-the-art 30-acre facility in the Boye County Rubber Industrial Park, Baoding, Hebei Province, China. We are an integrated global provider encompassing primary research & development, customized engineering design, chemical compounding, vulcanization, and worldwide after-sales deployment.
Our operation is structurally verified under international quality protocols, running highly automated calenders, high-pressure continuous press lines, and dedicated material laboratories. Our engineering core specializes in manufacturing high-strength textile reinforced belts (EP/NN/Polyester-Nylon), steel cord systems, and custom multi-layered specialty profiles designed to eliminate industrial downtime.
Heavy-duty bulk handling environments demand conveyor systems with zero-fault margins. We build high-performance systems engineered specifically for key global market challenges.
Capable of conveying sinter, coke, and slag at contact temperatures spikes exceeding 250°C. We compound premium EPDM and heat-resistant covers to prevent premature cover hardening, surface cracking, and ply separation.
Underground safety requires specialized flame-retardant (MSHA/DIN compliant) compounds that self-extinguish. Our anti-tear steel cord designs protect against longitudinal slitting caused by trapped tramp metal.
High-volume bulk handling lines require high belt speeds and low rolling resistance. We optimize bottom cover rubber properties to dramatically lower energy draw over long-distance conveyor runs.
Jinao® brand belts are engineered to match or exceed rigorous DIN 22102, ISO, AS, and RMA standards.
| Belt Type | Reinforcement Core | Tensile Strength (N/mm) | Cover Properties (DIN 22102) | Primary Application Context |
|---|---|---|---|---|
| EP (Polyester/Nylon) | Polyester Warp / Nylon Weft | 100 - 630 N/mm per ply | Grade X, Y, W, Z | Medium-long distance quarrying, sand, aggregates, and mining |
| NN (Nylon/Nylon) | Nylon Warp / Nylon Weft | 100 - 800 N/mm per ply | High Elasticity, Shock Resistant | Heavy impact environments, crushing lines, log handling |
| Steel Cord (ST) | Zinc-Coated Steel Wire Rope | ST630 - ST5400 | ISO 15236, Anti-Tear/Abrasion | Long overland paths, deep pit coal mining, port loadouts |
| Heat-Resistant (HR) | EP / Steel Cord Core | 200 - 3150 N/mm | T150, T200, T250 (EPDM/SBR) | Coke plants, cement clinker lines, chemical fertilizer plants |
| Chemical/Acid Resistant | Synthesized EP Fabric | 100 - 500 N/mm per ply | Neoprene/EPR specialized compound | Phosphate processing, seawater installations, pulp paper mills |
Our raw rubber compound processing to structural vulcanization is monitored continuously by automated thickness gauges and laser tracking systems.
Raw natural and synthetic rubbers are batched in our automated carbon black mixing center to ensure consistency.
High-precision 4-roll calenders apply uniform rubber coats onto textile plies or steel wire arrays.
High-pressure flat vulcanizers run closely monitored cure cycles to lock in cover adhesion and elasticity.
Each batch undergoes DIN abrasion test, steel cord pull-out testing, and dynamic fatigue checks in our laboratory.
From the mixing center to the final test bench, Hebei Boao Rubber Technology guarantees raw material purity and product durability.












Our manufacturing plant operates under strict adherence to ISO international guidelines, including API 6D, API 607, CE, ISO 9001, ISO 14001, and ISO 45001.
Jinao® brand belts are engineered to perform in demanding, high-throughput applications worldwide.
We provide full-lifecycle support, from belt design and selection to splicing, monitoring, and structural maintenance.
We provide scheduled replacement plans, wear rate modeling, physical inspections, and rapid mobilization for emergency belt repairs.
Our team calculates the proper step length and curing profiles for hot vulcanized or cold bonded splicing on site, ensuring up to 90%+ joint efficiency.
We analyze material path dynamics and wear patterns to recommend target compounds, reducing dust and mechanical strain on idlers.
