High-durability manufacturing solutions optimized for specialized and general heavy-duty applications.
Understanding the engineering, molecular properties, and rubber chemistry that defend against oil-based degradation.
Standard natural or SBR rubbers absorb hydrocarbons, causing volumetric swelling, delamination, and rapid tensile loss. We utilize premium Nitrile Butadiene Rubber (NBR) and Chloroprene (CR) matrices, ensuring a high-density molecular block against non-polar solvent intrusion.
We compound our covers to meet ASTM D2942, DIN 22102, and ISO 1817 regulations. By balancing Acrylonitrile (ACN) content in NBR formulations, we deliver solutions that perform under severe operational stress without embrittlement or structural softening.
Engineered with synthetic fabric carcasses (EP, NN) or high-tensile steel cord structures. These cores undergo specialized chemical bonding treatments to guarantee adhesion strength even in wet, oily, and high-abrasion applications.
| Compound Class | Primary Polymer Base | Volume Swelling (ASTM No. 3 Oil, 70h @ 70°C) | Primary Performance Target | Typical Applications |
|---|---|---|---|---|
| MOR (Medium Oil) | NBR + SBR Blend | ≤ 25% | Moderate chemical and mild plant oil resistance | Wood chips, crop processing, municipal compost, fertilizers |
| OR (High Oil) | Pure NBR | ≤ 10% | Excellent resistance to mineral oils, fuels, solvents | Metal working, recycling scrap, coal tar processing, oily grains |
| SOR (Super Oil) | High ACN NBR | ≤ 5% | Extreme resilience to aromatic hydrocarbons, hot oil | Oil-treated minerals, heavy chemical feed, hot asphalt mixes |
22+ Years of Advanced Elastomeric Manufacturing (Brand: "Jinao")
Established in 2004, Hebei Boao Rubber Technology Co., Ltd. sits within the heart of the Rubber Industrial Park of Boye County, Baoding, Hebei Province, China. Over a vast footprint exceeding 30 acres, we operate as a top-tier designer, researcher, and manufacturing partner for heavy industries worldwide.
Through our independent laboratory testing facilities, we control every single production link. From raw synthetic rubber polymer inspection to high-temperature vulcanization monitoring, no product leaves our factory gates without certification. We are fully compliant with ISO9001, ISO14001, and OHSAS18001 standards.
Why global heavy enterprises choose Hebei Boao for high-scale, reliable logistics.
Located in Boye, the rubber hub of Northern China, we enjoy rapid access to premium polymer producers, high-tensile steel cord suppliers, and structural fabrics (EP/NN). This reduces lead times and insulates our partners from global pricing shocks.
Our wide-width vulcanizing presses and advanced automation systems handle high-volume demands effortlessly. This capacity allows us to maintain consistent thickness and flat profiles, essential for belt trackers and scraper setups.
Proximity to Tianjin Port enables streamlined ocean container transport, rapid customs declarations, and flexible breakbulk routes. We provide reliable global delivery terms (FOB, CIF, DDP, CFR) under tight deadlines.
Aligning with local engineers, inspectors, and standards to ensure trouble-free commissioning.
Manufactured to strict global standards: API 6D, API 607, CE, ISO9001, ISO14001, ISO18001/45001, and TS certifications. Safe for chemical environments.
We collaborate with local distributors to manage regional safety stocks, minimizing costly downtime for mines, ports, and steel mills.
Engineered compounds designed for specific regional climates, from freezing Arctic ports to burning-hot desert mining plants.
Comprehensive support including technical joint bonding programs, hot vulcanizing materials supply, and preventive maintenance guides.
