The Whole Core Flame-Retardant Conveyor Belt is a high-performance industrial solution specifically engineered for hazardous environments where fire safety is paramount. Designed primarily for underground coal mine transportation, as well as metallurgical and chemical industries, these belts utilize an advanced impregnation and vulcanization process. By treating the entire belt core with a specialized polyvinyl chloride (PVC) paste, Roule ensures a product that combines high tensile strength and large capacity with critical safety features, including anti-static, impact-resistant, and corrosion-resistant properties.
Available in both PVC and PVG types, these belts are optimized for different operational inclinations and durability requirements. Whether navigating the strict safety regulations of a power plant or the abrasive conditions of a steel mill, our whole-core structure prevents delamination and suppresses flame propagation. By integrating flame-retardant agents directly into the rubber compound, the belt self-extinguishes once the heat source is removed, ensuring operational stability and protecting personnel in the world's most challenging work environments.
| Core Type | Whole Core Flame-Retardant | PVC Type Cover | Adhesive ≥ 0.8mm (Single-sided) |
|---|---|---|---|
| PVG Type Cover | Nitrile Rubber + PVC (1.5mm-4.5mm) | Max Inclination (PVC) | Less than 16° |
| Max Inclination (PVG) | Less than 20° | Key Properties | Flame Retardant, Anti-static, Wear-resistant |
| Production Process | Vulcanization & Plasticizing | Carcass Structure | High-tensile Synthetic Fiber |
| Application Areas | Mining, Metallurgy, Chemical | Safety Certification | International Fire Resistance Standards |

| Metric | Ordinary Conveyor Belt | Roule Flame-Retardant Belt |
|---|---|---|
| Fire Risk | High (Combustible) | Low (Self-extinguishing) |
| Service Life | Standard | Extended (Whole-core design) |
| Maintenance Cost | Frequent Replacements | Low (Reduced delamination) |
| Safety Compliance | Basic | Full International Standards |
| Operational Downtime | Higher risk of failure | Minimized through durability |
PVC belts feature a PVC cover adhesive (≥0.8mm) and are suitable for inclinations below 16°. PVG belts use a blend of Nitrile rubber and PVC (1.5mm-4.5mm), allowing for steeper inclinations up to 20°.
The whole-core structure eliminates traditional layers, preventing delamination and ensuring that flame-retardant agents are integrated throughout the belt, not just on the surface.
Yes, our belts are designed with corrosion-resistant and flame-retardant properties, making them ideal for chemical and metallurgical material transportation.
We incorporate specialized anti-static additives into the rubber compound to dissipate electricity generated by friction, preventing sparks in combustible environments.
All belts undergo rigorous testing, including flame propagation, drum friction, and tensile strength assessments within our modern 6,000-square-meter production facility.
On the contrary, the integrated core structure reduces the likelihood of layer separation and wear, leading to lower maintenance costs and fewer replacements over time.
Our conveyor products, including rollers, belts, drums, and accessories, have been successfully exported to numerous countries across industries like mining, ports, metallurgy, coal, and chemicals. With certifications like ISO, CE, and SGS, our reliable and efficient solutions meet international standards, earning trust from clients worldwide.
