Explore our highest-performing conveyor belts, idlers, and engineered solutions relied upon by global industrial leaders.
Founded in 2004, Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province, occupying an advanced industrial site covering over 30 acres. Our registered "Jinao" brand has evolved into a global symbol of durability, manufacturing precision, and high-performance engineering.
We are a leading, integrated manufacturer in China focusing on the end-to-end product development, physical-chemical testing, system design, and production of heavy-duty conveyor belts and matching conveyor machinery accessories. By passing international quality management system certifications in one go, Boao is dedicated to building robust industrial lines that maximize runtime and output for steel mills, mines, and material logistics hubs worldwide.
An uncompromising approach to mechanical reliability, compound science, and global field support.
Equipped with an independent chemical analysis lab and a physics/tensile laboratory, we monitor every supply-chain layer, from raw synthetic rubber polymer testing to final vulcanization metrics, maintaining zero defect tolerances.
Leveraging state-of-the-art testing equipment like dynamic fatigue testers, peeling test apparatuses, and steel-cord pull-out testing machines to guarantee long service lives under severe mechanical stress.
Designed and manufactured in accordance with strict international standards (DIN, ISO, AS, MSHA, BS, SANS). Our conveyor belts run optimally in steel plants, cement works, ports, and power generation lines worldwide.
How our smart manufacturing lines, high-precision vulcanizers, and material testing labs yield high efficiency.
Integrating automatic proportioning and feeding devices to eliminate human variance in compounding, ensuring chemical stability against ozone degradation and internal wear.
Utilizing high-precision multi-roll calendering machines to press rubber layers into synthetic plies (EP/NN fabric or Steel cords) at exact tension levels, securing superior inter-ply adhesion.
Our long-table vulcanizers apply uniform pressure and heat profiles, transforming compounds into resilient matrices that withstand extreme impact and thermal stress.
Each batch undergoes rigorous test protocols, including steel cord pull-out tests, dynamic fatigue testing, and cover-abrasion evaluations before packing.

| Carcass Type / Cover Compound | Tensile Strength (MPa) | Elongation at Break (%) | DIN Abrasion Loss (mm³) | Primary Industrial Use Case |
|---|---|---|---|---|
| Steel Wire Rope Core | 1000 - 5400 N/mm | ≤ 0.2% (low stretch) | 90 - 120 | Long-distance overland bulk transport (mining, port terminals) |
| Polyester (EP) Fabric Ply | EP100 - EP600 (Multi-ply) | ≤ 1.5% (elastic stretch) | 120 - 150 | Medium to long range coal, aggregate, and cement distribution |
| Nylon (NN) Carcass | NN100 - NN500 (Multi-ply) | ≤ 2.0% (high impact recovery) | 120 - 160 | High impact, heavy aggregate dump sites and rock crushing plants |
| Heat Resistant (HR / EPDM) | 15 - 18 MPa | ≥ 350% | 150 - 200 | Handling sinter, hot cement clinker, coke oven discharge up to 300°C |
| Flame Retardant (FR Rubber) | 18 - 24 MPa | ≥ 400% | 100 - 130 | Underground coal transport lines, grain silos (prevent dust explosions) |
| Chemical / Acid-Alkali Resistant | 14 - 17 MPa | ≥ 350% | 140 - 180 | Fertilizer processing plants, chemical transport, mineral refining |

How Boao systems adapt to the operational profiles of distinct heavy industries.
High-tension steel cord conveyor belts handle heavy ore output. Formulated cover compounds resist gouging from sharp granite, gold, copper, and iron ore blocks, minimizing tear propagation.
Jinao EPDM compounds transport hot sintering materials and coke discharge at temperatures peaking above 300°C without cracking, maintaining ply adhesion over prolonged cycles.
Optimized chevron, sidewall, and high-inclination wavy edge systems transport abrasive clinker and sand vertically or at steep angles, saving floor space in concrete batching plants.
We help plant managers eliminate downtime through structured planning, splicing services, and site inspections.
Preventive maintenance programs, on-site conveyor belt inspections, vulcanized hot/cold splicing joint services, and quick-response emergency repairs.
Supply of premium belts and splicing materials, management of safety stock levels, vulcanized structural joint design, cover rubber damage repairs, and system commissioning.
Reducing energy draw by aligning pulleys, tracking belts to stop edge wear, optimizing scraper wear, and extending belt service lifetimes.
Our certifications provide transparency, ensuring compliance with global industrial safety and environmental laws.
Qualified Standards: API 6D, API 607, CE, ISO9001 Quality Management, ISO14001 Environmental Protection, ISO45001 Occupational Safety. Contact us to request original test documents.
