Explore our primary industrial production segments. Manufactured at our state-of-the-art Boye Rubber Industrial Park, engineered for resilience and optimal power transmission.
Established in 2004 and situated inside the Boye County Rubber Industrial Park in Baoding, Hebei, China, Hebei Boao Rubber Technology Co., Ltd. covers an expansive area of over 30 acres. For over 22 years, we have committed to manufacturing international-grade industrial beltings under our prestigious proprietary trademark, the "Jinao" brand.
We provide comprehensive engineering services, integrating design, advanced chemical research, fabrication, and global logistics for high-demand flat rubber drive belts, conveyor lines, and heavy-duty conveyor accessories. As an ISO 9001, ISO 14001, and ISO 45001 certified plant, we operate multi-stage chemical analysis and physical testing laboratories that ensure every rubber compound and reinforcing core exceeds typical performance standards.
The evolution of flat rubber drive belts centers on polymer chemistry optimization. Utilizing Chloroprene (CR), EPDM, SBR, and natural rubber matrixes, Boao manufactures flat belts characterized by high friction coefficients and negligible stretching. Continuous research focuses on carboxylated nitrile rubber compounds that resist petroleum-based lubricants and synthetic ester-based processing oils.
To eliminate systemic elongation and structural hysteresis under extreme RPMs, our carcass reinforcement layers incorporate high-modulus polyester (EP) plies, polyamide (NN) structures, and high-tensile aramid fibers. This ensures minimal flex fatigue, maximum longitudinal strength, and outstanding cross-rigidity to tolerate continuous reverse bending stress.
The future of heavy-duty flat conveyance relies on embedded technology. Boao is researching smart belting options integrated with UHF RFID and magnetic sensor implants. These advanced belts provide real-time telemetry on ply-adhesion degradation, surface wear, micro-tears, and structural fatigue, facilitating predictive maintenance cycles.
Industrial equipment is only as reliable as its drive core. We develop custom solutions for major sectors nationwide:
Operating under extreme thermal cycles and slag abrasion. Our heat-resistant conveyor and transmission lines operate safely up to constant temperatures of 250°C and peak temperatures of 400°C, serving facilities like Taihang Steel and Tsingshan Group.
Demanding explosion-proof materials and fire safety compliance. Our MT820 / DIN EN ISO 340 flame retardant belts prevent combustion risks in confined underground shafts, heavily deployed by Datong Coal Group and Jinmei Group.
Where sharp silica, limestone dust, and high mechanical shock lead to rapid wear. Our high-adhesion SBR/Nitrile covers provide excellent impact resistance, serving massive projects for Conch Cement and Jidong Cement Group.

At Hebei Boao Rubber Technology, we run automated batching and compounding systems that guarantee chemical formulation stability across production runs. Our heavy-duty rolling, shaping, and continuous vulcanization lines eliminate ply shifting and localized density issues common in older manufacturing facilities.
Our multi-roll precision calendering machinery guarantees consistent thickness profiles. Combined with computerized pressure and temperature controls during the vulcanizing stage, we produce cross-sectionally stable flat drive belts with excellent surface uniformity.
Equipped with dynamic fatigue testers, peeling resistance machines, and steel cord pull-out rigs, our facility monitors performance parameters from raw rubber compound arrivals to finished dispatch, adhering to our strict zero-defect policy.
Our rubber belt configurations conform to dynamic testing benchmarks established by international regulatory frameworks. We comply strictly with API 6D, API 607, CE, ISO9001, ISO14001, ISO45001, and TS certifications, satisfying specific regional compliance requirements.
We run testing labs to ensure zero-defect outcomes before shipments depart Boye. Standard verification steps include density evaluation, tensile strength tests (MPa), cover elongation at break tests, abrasion loss verification (DIN 53516 < 90mm³), and multi-point ozone degradation assessments.
Our support extends beyond the factory floor. We offer comprehensive engineering plans, including system calculations, scheduled replacements, vulcanized splicing assistance, rubber cover repair guidelines, and preventative onsite maintenance programs.
When evaluating high-capacity flat rubber drive belts or belt conveyors, procurement teams should inspect key operational indicators:
Match the belt strength profile (e.g., EP 100 to EP 500 or Steel Cord ST 5400) to system tension requirements. Splicing zones must achieve at least 90% of parent material strength using hot vulcanization or mechanical fasteners.
The inter-ply adhesion value must exceed 6.0 N/mm for fabric belts to prevent delamination. Surface rubber formulations must balance high coefficient of friction with wear resistance to minimize slip on the drive pulley.
Specify target resistance properties: flame retardance (DIN EN ISO 340), oil resistance (volume swelling < 5% in oil), heat tolerance (up to 200°C continuous), or cold-temperature flexibility (down to -50°C).
Select from our specialized line of high-durability rollers, steel-wire reinforced cores, and fire-resistant configurations built to DIN/ISO standards.
