In November 2025, YIQI Conveyor successfully completed the production of a 260-meter heat-resistant conveyor belt designed for sustained operation under temperatures up to 150°C. This belt will soon be shipped to a long-term Philippine client specializing in cement and steel processing, where continuous heat exposure is part of daily production.
The new belt demonstrates YIQI's commitment to providing tailor-made conveying solutions that ensure durability, energy efficiency, and long service life even in extreme environments.
Material Structure and Composition
The heat-resistant conveyor belt is engineered with a robust multilayer design to handle both high temperatures and mechanical stress:
- Top & Bottom Rubber Cover: Made from EPDM heat-resistant rubber compounds, offering exceptional resistance to hardening and cracking.
- Reinforcement Layer: High-strength EP fabric (EP150 × 5) ensures excellent adhesion and dimensional stability.
- Adhesion System: Advanced vulcanization technology for superior bonding between layers.
- Temperature Range: Continuous operation up to 150°C, with peak tolerance up to 180°C for short intervals.
Key Performance Features
| Feature | Description |
| Heat Resistance | Stable operation at 150°C continuous temperature |
| Durability | Long lifespan under thermal cycling and heavy loads |
| Tensile Strength | High EP fabric ensures excellent load capacity |
| Crack Resistance | EPDM compound resists hardening and surface cracking |
| Energy Efficiency | Low elongation and smooth tracking reduce power loss |
| Safety & Compliance | Meets ISO 4195 and DIN 22102 heat-resistant belt standards |
Applications in High-Temperature Industries
Heat-resistant conveyor belts are essential in sectors where materials are transported directly from high-temperature processes. YIQI's 150°C-rated belt is suitable for:
- Cement plants – clinker conveying, hot limestone, and kiln feed systems
- Steel and metallurgical industries – handling of sinter, coke, and hot slag
- Power plants – transportation of hot ash and fly dust
- Fertilizer production – conveying of chemical materials post-drying
- Recycling and foundry operations – metal waste and hot scrap handling
Comparison: Heat-Resistant vs. Standard Conveyor Belts
| Feature | Heat-Resistant Belt | Standard Belt |
| Operating Temperature | Up to 150°C | Below 80°C |
| Rubber Hardness | Stable, low aging | Tends to harden |
| Flexibility | Maintained after long exposure | Decreases rapidly |
| Service Life | 3–5× longer | Shorter lifespan |
| Maintenance Cost | Low | High due to frequent replacement |
Production and Quality Control
YIQI Conveyor follows strict inspection protocols during each production stage to ensure quality and consistency:
1. Material Inspection – Each batch of rubber compound is tested for heat aging, tensile strength, and elongation.
2. Fabric Testing – EP fabrics are inspected for adhesion, tensile strength, and dimensional accuracy.
3. Vulcanization Control – Temperature and pressure are monitored in real time to ensure uniform bonding.
4. Final Testing – Each belt undergoes surface inspection, hardness testing, and tensile simulation before packing.
Client Benefits
By upgrading to YIQI's high-temperature resistant conveyor belt, clients benefit from:
- Extended belt life and reduced downtime
- Improved process efficiency under continuous high-temperature operations
- Lower maintenance and replacement costs
- Better belt tracking due to dimensional stability
- Increased safety through reduced risk of belt failure in hot zones
