Engineered for extreme performance across major global industrial sectors, including mining, heavy metallurgy, and bulk ports.
Hebei Boao Rubber Technology Co., Ltd. is located in the prominent Rubber Industrial Park of Boye County, Baoding, Hebei Province, China. Established in 2004, our manufacturing facility covers more than 30 acres of high-density production zone, integrating modern technology with classic raw materials expertise.
Under our flagship brand name "Jinao", we develop, design, and manufacture robust heavy-duty conveyor belts and accessories. We have passed the international quality management system certification in one go. Our facility operates multiple advanced manufacturing lines for rolling, calendering, forming, and vulcanization, guaranteeing continuous control from raw polymer compounds to final high-tension rubber belts.
Analyzing critical logistical vulnerabilities in the modern industrial landscape and resolving them through custom polymer formulation.
Standard flat rubber belt materials degrade rapidly under temperatures above 120°C. Our compound blends utilize EPDM and special synthetic elastomers to withstand dry bulk materials up to 250°C, reducing operational shut-down cycles.
Corrosive elements in fertilizer processing and wet mining demand high resistance. "Jinao" acid-and-alkali resistant belts combine NBR and specialized rubbers to stop chemical swelling, preserving ply adhesion.
Heavy drop zones in coal mines and quarries cause longitudinal tearing. We embed high-tensile steel wire cords and transverse reinforcing layers to deflect vertical impact, ensuring catastrophic tear containment.
Direct supply from Hebei Boao manufacturing pipelines, engineered to meet international safety and structural specifications.
High modulus, low elongation polyester fabric carcass offering outstanding dimensional stability.
Specially molded side reinforcement prevents spillage during horizontal conveying routes.
Folds into a tubular cross-section to transport powder materials cleanly and securely.
Tailored compound matrix prevents cracking, hardening, and shrinkage under extreme temperatures.
Optimized for polar mining conditions down to -50°C, maintaining elasticity and flexibility.
Strong resistance to acids, alkalis, and chemical degradation in chemical industries.
Outstanding flexibility, high impact absorption, and supreme flex-fatigue life expectancy.
Cost-effective daily handling solutions for aggregates, gravel, and earth-moving projects.
Zero compromises on quality assurance. Our chemical labs and testing equipment monitor every production run from raw compound mix to final dispatch.
Deploying heavy-duty conveyor solutions inside major domestic and international manufacturing hubs.
Our flat rubber conveyor belts have served heavy industrial environments including Jidong Cement Group, Jinmei Group Coal Conveying Line, and Puyang Steel Group. These applications confirm our belts' ability to maintain mechanical integrity under intense pressure, extreme load variations, and abrasive contact.
Pioneering smart conveyor systems and next-generation polymer compositions for sustainable industrial development.
We are embedding micro-sensors and copper scan loops inside high-tension EP and Steel Cord conveyor belts. These sensors detect longitudinal tears instantly and trigger automatic system shutdowns before severe line damage occurs.
By integrating renewable, bio-based vulcanization agents and recycled polymer raw materials, our new compound lines decrease total manufacturing carbon footprint by up to 25% while maintaining peak tear strength.
Our upcoming wear covers yield less than 50 mm³ volume loss under DIN 53516 testing conditions. This extended operational lifespan reduces total bulk terminal material handling overhead by up to 30%.
To secure smooth bulk handling, we supply physical belts along with comprehensive installation, calibration, and preventive maintenance guides.

Conforms to global underground mining safety requirements, containing fire risks in enclosed tunnels.
Direct answers from our polymer chemists and system engineers regarding belt materials, lifespan, and specifications.
EP (Polyester warp / Polyamide weft) belts exhibit high tensile strength, minimal stretching under high loads, and excellent resistance to water damage. NN (Nylon warp / Nylon weft) belts offer superior elasticity, higher flex fatigue life, and high shock resistance. NN belts are ideal for high-speed, long-distance lines with high impact zones.
We perform systematic laboratory testing in line with international requirements (such as DIN EN 12882 and ISO 340). These protocols evaluate surface electrical resistance alongside flame propagation and duration of afterglow after direct fire exposure. This process ensures safety in underground coal mining configurations.
Common failures result from off-center tracking, high impact at transfer chutes, and chemical swelling from oils or acids. We address these issues by combining custom-engineered rubber compounds with structural components like buffer rollers, tracking brackets, and impact beds to absorb point loads.
Standard widths (up to 1600mm) are generally fulfilled within 15–20 days, depending on fabric carcass availability. Custom-compounded formulations (such as heat or acid resistant covers) typically require 25-30 days to complete mixing, calendering, and final vulcanization cycles.
Ensuring system durability and material flow reliability in demanding global bulk handling pipelines.
