Explore our primary range of heavy-duty conveyor belts, idler rollers, and custom brackets engineered to perform in extreme physical and chemical environments globally.
Founded in 2004, Hebei Boao Rubber Technology Co., Ltd. is situated in the prestigious Rubber Industrial Park of Boye County, Baoding, Hebei Province, China. Spanning an expansive area of over 30 acres, we have established ourselves as an industry leader in engineering high-performance rubber systems. Our signature brand, "Jinao", is synonymous with structural integrity, exceptional material longevity, and advanced elastomeric performance.
As a highly integrated manufacturer, we encompass the entire product lifecycle—from raw elastomer chemical synthesis, compounding, vulcanization modeling, to mechanical component assembly. Our operation is certified under the ISO9001 International Quality Management System, verifying that our production procedures adhere strictly to global manufacturing benchmarks.
Our commitment to precision engineering, structural diagnostics, and end-to-end quality assurance separates us from typical suppliers.
Our in-house physics laboratory and chemical analysis facility enable scientific validation of all incoming raw polymers. We monitor molecular structural parameters to guarantee zero-defect production before vulcanization begins.
Using advanced abrasion, peeling, and dynamic fatigue testers, our certified QA engineers perform structural checks on every batch. Testing certificates are provided for complete batch traceability.
Our engineered solutions are deployed worldwide in major heavy-duty industries, including metallurgical mining, coal generation plants, cement manufacture, commercial agricultural processing, and busy cargo ports.
Conveyor belts operating in environments laden with hydrocarbons, animal fats, or vegetable lipids face severe degradation challenges. When standard SBR (Styrene Butadiene Rubber) or natural rubber belts come into contact with oils, the non-polar molecules of the oil diffuse into the cross-linked rubber matrix. This causes molecular swelling, which leads to physical deformation, reduced tensile strength, cover stripping, and eventual structural delamination.
To prevent these operational failures, Hebei Boao utilizes specialized elastomer formulations, primarily utilizing Nitrile Butadiene Rubber (NBR). The level of oil resistance is directly related to the Acrylonitrile (ACN) content in the NBR compound. Higher ACN levels provide exceptional resistance to swelling, chemical penetration, and structural breakdown, though they can reduce flexibility in extremely cold temperatures. Our engineers carefully balance these properties to design belts optimized for specific temperature and chemical conditions.
When selecting a compound, it is critical to evaluate the type of oil handled. For example, mineral oils are highly aggressive toward low-polarity rubber. Utilizing an optimized NBR/PVC blend or premium high-ACN NBR ensures the belt maintains its tensile properties and resists edge curling, even during continuous contact with cutting fluids or fuel oils.
| Grade Designation | Elastomeric Compound Type | Target Applications | Key Performance Indicators |
|---|---|---|---|
| Grade MOR (Medium Oil Resistant) | NBR / SBR Blends | Woodchips, compost, grain processing, light agricultural feed | Good balance of abrasion resistance and moderate fat resistance. |
| Grade OR (Oil Resistant / NBR Heavy) | High-ACN Nitrile Butadiene Rubber | Metal recycling, mineral oil mixtures, oil-treated coal, fertilizers | Excellent resistance to swelling under continuous exposure to mineral oils. |
| Grade G (Specialized Oil & Heat) | Nitrile / EPDM hybrid compound | Hot asphalt, oil-treated cement clinker, high-temp oil sands | Resists structural oxidation and swelling at operating temperatures up to 120°C. |
At Hebei Boao Rubber Technology, we integrate modern manufacturing automation with structured process controls. Our production facilities feature automated compounding systems that precisely measure and mix rubber formulations. This guarantees batch-to-batch consistency in elastomer density, tensile strength, and curing performance.
Our manufacturing infrastructure includes multi-cylinder heavy-duty calenders and high-pressure vulcanization presses. These systems ensure uniform pressure and heat distribution across the belt's length. Additionally, our location in the Boye County industrial cluster provides a highly reliable supply chain. This enables us to source raw materials, technical reinforcements, and components efficiently, minimizing delivery lead times for global projects.
Our manufacturing facility features dedicated quality assurance equipment, ensuring every stage of production conforms to international standards prior to shipment.

Our conveyor belts are engineered to meet the operational demands of heavy industry, including oil resistance, extreme temperatures, and chemical exposure. We collaborate with leading engineering firms to design customized solutions for challenging processing and transport applications.
Handling soybeans, canola, rapeseed, and corn germ exposes belts to high concentrations of plant-based lipids. Under these conditions, standard belts quickly soften and stretch. Our food-grade NBR oil-resistant belts maintain tension, resist swelling, and prevent microbial accumulation on the belt surface.
Scrap metal transport systems handle materials covered in synthetic cutting fluids, lubricants, and sharp metal edges. Our steel-reinforced oil-resistant conveyor belts are engineered with premium cut-and-gouge resistant rubber compounds to handle these challenging operating conditions.
Transporting raw materials treated with anti-dusting oils requires a belt that provides both chemical stability and oil resistance. Our advanced multi-ply EP conveyor belts are engineered to resist chemical deterioration, preventing ply separation and premature belt failure.
Our industrial products are used globally by major steel, mining, and cement producers, delivering reliable performance in demanding operating environments.
