Direct supply from Hebei Boao's ISO certified manufacturing line. Engineered for severe thermal operations.
Mitigating thermomechanical stress across heavy-duty global supply chains.
In basic oxygen steelmaking, cement production, and mineral roasting, materials often exit reactors at temperatures exceeding 250°C. Standard conveyor belts exposed to such extreme heat suffer rapid elastomer degradation, ply separation, and micro-cracking of the cover rubber. Our heat resistant conveyor belts are specifically formulated using high-performance EPDM (Ethylene Propylene Diene Monomer) matrices. This advanced compound retains its polymer cross-linking stability under prolonged thermal exposure, shielding the core polyester (EP) or steel cord reinforcement from mechanical fatigue and premature elongation.
Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province. Founded in 2004 and spanning over 30 acres, Boao has established itself as an authoritative manufacturer integrating product research, design, engineering, and global services for conveyor belts and supporting machinery accessories.
Our brand "Jinao" represents our core promise: consistent performance, premium polymer chemistry, and rigorous quality assurance. We operate multiple advanced lines for rolling, shaping, vulcanization, and material testing—insulating our clients from the risks of conveyor line downtime.

Hebei Boao’s Jinao brand utilizes dynamic vulcanization processes that control the cross-link density of EPDM rubbers. This reduces polymer chain degradation under thermodynamic stress and ensures stable tensile strength and elongation metrics over the belt’s functional lifecycle.
Scientific validation of raw compounds to finished rubber systems.
Our state-of-the-art laboratory monitors every batch from raw material procurement to product delivery. We strictly execute the policy: "Unqualified raw materials do not enter the site, and sub-standard finished products never leave the factory."
Globally recognized standards supporting structural safety and longevity
Direct field performance with top tier industrial enterprises.
Maximizing plant productivity and belt lifespans with managed maintenance services.
Our relationship with clients extends beyond supplying premium rubber belts. We develop custom service and technical plans to handle belt replacements, joint hot-vulcanization, inspection schedules, surface repair, and safety stock management.
