Hebei BAO’s Heat Resistant (HR) Conveyor Belts are engineered specifically to transport high-temperature bulk materials without compromising belt integrity or service life. Utilizing specialized synthetic rubber compounds (EPDM or Butyl) and a high-modulus textile carcass, our HR belts prevent early aging, cracking, and hardening common in standard belts subjected to heat. We provide customized solutions to meet all international heat classes (T1 to T4), ensuring maximum uptime and safety in high-thermal processing environments.
Key Features
- Exceptional Thermal Stability
- Specialized EPDM Rubber Compound
- Long-Lasting Ply Adhesion
- Prevents Cracking and Hardening
- Reduced Belt Surface Aging
- Customized Temperature Grading
Applications & Industries
Cement and Clinker Plants
Handles hot clinker, gypsum, and raw materials often reaching high temperatures efficiently.
Steel and Metallurgical Mills
Used for transporting heated ore, coke, and sintering materials in extreme thermal conditions.
Sintering and Coking Plants
Withstands the high continuous heat and brief temperature spikes of freshly produced coke.
Chemical and Fertilizer Processing

FAQs
1. How do HR belts maintain strength at high temperatures?
HR belts use heat-stable synthetic carcass fabrics (like EP) and specialized polymer covers (EPDM/Butyl) which are chemically designed to resist thermal oxidation.
2. Can I get an HR belt that is also highly abrasion resistant?
Yes, we customize the formulation. We can balance the heat resistance polymers with robust carbon black fillers to achieve superior abrasion performance in hot conditions.
3. What is the typical service life reduction for HR belts?
While heat reduces life, a correctly specified HR belt (T2, T3, etc.) will provide a durable service life of several years, significantly longer than an overstressed standard belt.
4. Is splicing different for heat resistant belts?
Yes, HR belts require specialized heat-resistant splicing compounds and often require higher vulcanizing temperatures to ensure the splice integrity matches the belt's thermal rating.
5. What information do you need to recommend the correct T-Class?
We require the maximum temperature of the material, the ambient temperature, the material particle size, and the frequency of use (continuous or intermittent).
6. Do HR belts require specialized cleaners or maintenance?
HR belts should not be cleaned with petroleum-based solvents. We recommend standard brushes and scrapers, and regular inspection for thermal cracks.
