Ultra Heat Resistant UHR Grade Conveyor Belt

HILFLEX® Ultra Heat Resistant Rubber Conveyor Belts (250 & 300 Series)

Uncompromising Performance for Extreme Temperatures up to 300°C

For the Hottest Materials on Earth. Uncompromising Performance.

When the material temperature crosses 250°C and nothing less than exceptional will do, HILFLEX® 250 & 300 Series belts deliver unmatched heat resistance and durability. These belts are specially designed to perform where standard heat-resistant belts fail—handling the harshest loads like red-hot sinter, furnace discharge slag, boiler ash, and more.

Engineered with proprietary EPDM-based compounds, they offer sustained performance in continuous temperatures up to 300°C, making them the ultimate solution for extreme heat industrial material handling.

♨️ Extreme Thermal Endurance – Compliant with IS 1891 (Part II)

Every HILFLEX® UHR belt is crafted using a next-generation EPDM compound designed specifically for ultra-high heat exposure. Even during continuous contact with blazing materials, these belts retain their physical integrity and structural stability.
They are engineered to resist:

• Severe Hardening & Brittleness due to thermal aging
• Deep Cracking & Surface Glazing from repeated heat cycles
• Softening & Loss of Adhesion under extreme stress

Available Grades (As per IS 1891 Part II):

💪 Engineered for the Harshest Industrial Conditions

More than just heat-resistant, these belts are fortified to endure the most aggressive mechanical, thermal, and impact conditions:

• Advanced Carcass Structure:
  Multi-ply EP or NN fabrics treated to resist shrinkage and maintain dimensional stability even in high-heat cycles.
• Reinforced Bonding:
  Enhanced adhesion between layers prevents delamination, ensuring structural safety during extreme thermal shock.
• Outstanding Wear Resistance:
  High-abrasion top cover handles slag, clinker, coke, and other rough materials without cutting or gouging the belt.
• Flexible at High Temps:
  Maintains pliability over pulleys and idlers, reducing mechanical strain and extending pulley life.

✅ Key Benefits of HILFLEX® Ultra Heat Resistant Belts

• Maximum Uptime: Built to endure without cracking, deforming, or disintegrating under the highest material temperatures.
• Low Lifecycle Costs: Longer service life and fewer breakdowns reduce maintenance frequency and spare part replacement.
• High Operational Safety: Withstands aggressive conditions without failure, protecting people, equipment, and processes.
• Consistent Throughput: Ensures uninterrupted flow of high-temperature materials, avoiding production delays.
• Custom Options: Available with RipStop, flame retardant properties, oil resistance, or other customizations based on material type and handling requirements.

🏭 Industries & Applications That Demand UHR Belts

These belts are indispensable in facilities with extreme process temperatures and continuous bulk handling:

• Sinter & Pellet Plants – Hot sinters and pellets at discharge points
• Steel & Iron Foundries – Red-hot castings, hot molding sand
• Furnace Discharge Systems – Slag and direct furnace material handling
• Cement Plants – Clinker handling from rotary kilns
• Thermal Power Stations – High-temperature ash disposal systems
• Incineration Units & WtE Plants – Handling incinerator ash and waste byproducts
• Coke Plants – Coke handling in dry quenching zones

💡 Recommendations for Maximizing Belt Life

Even with ultra-heat resistance, optimal belt performance depends on several critical factors:

• Material Abrasiveness: Rough and sharp particles accelerate wear.
• Loading Impact: Minimize free fall and control material flow at loading points.
• Material Size & Shape: Sharp edges can lead to surface cuts or gouging.
• Belt Length & Speed: Long and high-speed belts require special considerations for heat dissipation.
• Chemical Exposure: Combustion residue or chemical fumes may degrade standard compounds.

💡 Use of thicker top covers (5 mm or more) is highly recommended to shield the carcass from direct heat.
