Hebei Boao Rubber Technology Co., Ltd. is located in the prominent Rubber Industrial Park of Boye County, Baoding, Hebei Province. Founded in 2004, our production facility spans over an expansive 30 acres, hosting state-of-the-art heavy industrial rubber compound mixers, precision calenders, and massive vulcanizing presses.
Under our flagship brand "Jinao", we are a professional manufacturer in China that integrates product development, research, design, manufacturing, and business services for conveyor belts and conveyor machinery accessories. We have also passed the international quality management system certification in one go. The company has multiple advanced equipment production lines for rolling, forming, vulcanization, and rubber testing (from raw materials to finished products).
Our commitment to E-E-A-T principles is backed by our physics and chemistry testing labs, ensuring high reliability for critical bulk material logistics.
The company has an independent chemical analysis room and physics laboratory, which can ensure timely monitoring of every link from raw material procurement to product delivery. It strictly follows the principle of not entering the site for unqualified products and not leaving the site for products that do not meet standards.
Professional quality inspectors, sophisticated experimental testing equipment (including electronic tensile testers, DIN abrasion wheels, ozone aging chambers), and advanced testing methods ensure the quality of the company's products.
With strong technical strength and a comprehensive after-sales system, our products are exported to various parts of the country and international hubs. Widely used in major industries such as steel, metallurgy, coal, cement, power generation, fertilizers, grain depots, ports, etc.
Our industrial products span across specialized conveyor belting sheets, custom profile configurations, and engineered steel supports.

When designing heavy-duty bulk handling systems, specifying the correct internal reinforcement carcass is vital. Polyester (EP) conveyor belts utilize polyester warp fibers and polyamide (nylon) weft fibers. EP belts exhibit low longitudinal elongation under tension, coupled with good transverse flexibility, translating to excellent troughing capabilities. Nylon (NN) carcass belts deliver superior elasticity and resistance to impact damage, making them optimal for mines where physical tearing and heavy aggregate impacts occur. For long-distance overland conveying systems (e.g. over 1km spans), Steel Wire Rope Core (Steel Cord) belts provide high tensile capacity with minimal elongation, ensuring stability over extensive linear networks.
| Carcass Type | Tensile Strength Range | Elongation at Max Load | Impact Resistance | Troughability Ratio | Primary Applications |
|---|---|---|---|---|---|
| Polyester (EP) | 100 - 630 N/mm per ply | ≤ 1.5% | Medium-High | Excellent (≥ 3.2) | Aggregate, Sand, Sinter, General Bulk |
| Nylon (NN) | 100 - 800 N/mm per ply | ≤ 2.5% | High (Severe Shock) | Good (≥ 2.8) | Hard Rock Mining, Heavy Quarrying |
| Steel Cord (ST) | ST 500 - ST 5400 | ≤ 0.25% | Extreme (Tear Resistant) | Rigid/Trough (customized) | Long-distance Overland, Deep Shaft Mines |
Standard rubber compounds degrade quickly when exposed to ozone, acidic solutions, petroleum oils, or extreme temperatures. To guarantee durability, Hebei Boao Rubber uses custom polymers:
The interaction between the rubber belt sheet and structural supports defines system efficiency. Friction coefficients must be managed. Standard bare steel rollers are prone to material buildup and slippage, leading to belt tracking errors. By deploying Ceramic Lagging Rollers with vulcanized ceramic tiles, the system friction increases, eliminating slippage in wet conditions. The geometry of Troughing Brackets (typically 30° to 45°) shapes the conveyor into a trough, preventing material spillover and maximizing volume throughput.
Our Jinao brand products have been implemented across major industrial facilities, confirming their durability in high-load settings.

Our goal is to improve the overall operational efficiency of the belt conveyor, minimize unexpected downtime, reduce the structural power requirements of motors by minimizing rolling resistance, and optimize tensioning variables.
Safety stock: Our logistics warehouse maintains safety stock margins tailored for contracted plants, minimizing lead time and ensuring backup conveyor components are ready during plant maintenance schedules.
Find direct, engineered answers to common queries regarding heavy rubber belting applications.
EP (Polyester) belts are suitable for systems requiring low elongation (under 1.5%) and high dimensional stability, making them the standard choice for most industrial overland conveyors. NN (Nylon) belts offer higher impact resistance and flex fatigue life, making them suitable for heavy raw material dump zones and primary rock crushers where they withstand sharp rocks and severe structural strain.
Heat-resistant rubber belts are categorized based on their heat aging capabilities:
Our raw synthetic elastomers (EPDM, NBR, SBR) and natural rubber blocks are sourced from accredited chemical suppliers. Before entering the mixing line, each batch is tested in our chemical analysis lab. We verify density, vulcanization cure rates, Mooney viscosity, and carbon black dispersion levels. Material tracking codes are assigned to ensure quality control from formulation to curing.
Hot Cured Splicing uses a portable vulcanizing press with heat and pressure to chemically cure the joint, restoring up to 90% of the belt's original tensile strength. It is the preferred method for high-load and steel cord belts. Cold Splicing utilizes chemical adhesives to bond the joint at room temperature, which is suitable for temporary repairs or lower tension fabric belts where downtime must be kept to a minimum.
Yes. Our conveyor belts are manufactured to comply with global standards including DIN 22102 (Germany), AS 1332 (Australia), RMA (USA), and ISO specifications. Our flame retardant belts undergo testing to meet national fire hazard guidelines for underground environments.
