Located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. integrates advanced research and development, design, and manufacturing under our renowned brand "Jinao". With our state-of-the-art rolling, forming, vulcanization, and chemical laboratories, we provide full quality control from raw materials to finished products.
Our Quality Assurance strategy relies on two key structural blocks:
Meeting Global Compliance Standards: API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and TS
ISO9001 Certificate
Environmental Certificate
Occupational Health
Production Safety License
Quality Assurance Certificate
In heavy industrial conveyor setups, a Supermax 25x2 specification refers to a robust structure offering a 25mm total profile thickness with 2 heavy-duty carcass reinforcement plies. This combination balances structural flexibility with carcass resistance. It supports dynamic load distribution across deep trough configurations (35° to 45° idler sets) without risking longitudinal splitting or ply separation.
The cover rubber features a high-grade elastomer blend (typically SBR mixed with Natural Rubber or Nitrile compounds) tailored to withstand constant impact forces. The 2-ply high-modulus carcass utilizes EP (Polyester-Polyamide) or NN (Nylon-Nylon) fabrics, offering high tensile strength, minimal elastic stretch, and impact energy absorption.
To assist technical procurement teams, the table below highlights standard specifications for our high-capacity conveyor belt series:
| Specification Parameter | NN/EP Fabric Reinforced | Steel Wire Rope Core | Testing Standard References |
|---|---|---|---|
| Tensile Strength (N/mm) | 500 - 3150 N/mm | Up to 5400 N/mm | GB/T 7984, DIN 22102 |
| Abrasion Loss (mm³) | < 90 mm³ (Super Wear-Resistant) | < 120 mm³ (Standard Heavy Duty) | DIN 53516, ISO 4649 |
| Elongation at Break (%) | ≥ 450% (Cover Rubber) | ≥ 400% | ASTM D412 |
| Adhesion Force (Carcass-Cover) | ≥ 8.0 N/mm | ≥ 10.0 N/mm | ISO 252 |
Our heavy duty rubber conveyor systems handle abrasive aggregates, sand, and high-load cement mixtures, maintaining stable operation in continuous concrete production lines.
Using heat-resistant Jinao-brand conveyor belts, Conch Cement achieved constant transport of hot clinker (up to 200°C), reducing unexpected replacement cycles.
Our flame-retardant, anti-tear steel cord belts are deployed in deep-shaft coal operations to ensure safe transport and prevent safety risks in explosive environments.
Providing heavy-duty acid, alkali, and oil resistant belts to Tsingshan's nickel processing operations, resisting chemical wear and high structural stress.
Designed to handle high impact and sharp iron ore feeds. Our belts reduce carcass puncture risks by using high-density carcass weaves and specialized rubber covers.
High-temperature sinter transport lines equipped with Jinao conveyor belts deliver consistent performance under constant heat exposure up to 250°C.
Our production floor features modern mixing, calendering, and curing systems. Automatic dosing controls raw materials, while high-pressure vulcanizers ensure even thermal cure profiles across the belt width.

In response to smart mining and automated factory trends, Hebei Boao Rubber Technology is researching integrated sensor conveyor belts. By vulcanizing RFID chips and high-frequency sensor loops directly into the belt carcass, operators can monitor internal temperature profiles, tracking alignment, and longitudinal rip detection in real time, preventing major structural failures.
Environmental standards require reducing VOCs and carbon footprints. Our technical roadmap focuses on developing energy-saving cover rubber compounds that lower rolling resistance over idlers. This technology can reduce conveyor power requirements by up to 15% on long-distance, high-capacity systems.
We provide planned replacement, repair, inspections, maintenance, and emergency splicing support for heavy-duty belt systems.
We supply vulcanized splicing materials and cover repairs, maintain safety stocks for quick dispatch, and assist with conveyor system optimization.
We aim to increase overall belt operational lifespan, reduce energy consumption, and lower operational costs for our clients.
Our field services follow strict international safety standards, minimizing plant downtime during maintenance windows.
Service life depends on the materials handled, drop heights, feed speeds, and chute designs. Our Supermax series features high-grade DIN-wear resistant compounds, typically delivering 30% to 50% longer life compared to standard general-purpose belts under abrasive load conditions.
EP fabric features a polyester warp (longitudinal) and polyamide weft (transverse), providing low stretch under load and excellent troughability. NN fabric uses polyamide for both warp and weft, offering high impact resistance and elasticity, making it suitable for long-distance, high-shock transport paths.
We recommend hot vulcanized splicing using matching Jinao raw tie gum and cover compounds. Hot splicing preserves up to 90% of original carcass strength. Cold adhesive bond systems should only be used for temporary repairs or lightweight applications.
Our chemically resistant belts use specialized inert rubbers (such as EPDM or Chloroprene blends) designed to resist acid and alkaline compounds. This formulation prevents swelling, hardening, and cracking when conveying chemical fertilizers, salts, or wet ores.
