Heat Resistant Conveyor Belt
High Temperature Resistant Fabric Conveyor Belt for Hot Material Handling
Heat resistant conveyor belts are specially designed for conveying high temperature materials such as sintering ore, coke, cement clinker, and hot bulk materials in industries like metallurgy, cement, and chemical processing.
Built for Extreme Conditions,
Trusted Across Industries
When conventional belts fail under high heat, our heat resistant conveyor belt delivers consistent performance. Engineered with advanced rubber compounds, it transports the hottest bulk materials safely, reliably, and with significantly longer service life — reducing downtime and replacement costs.
- Sintering ore — from blast furnace processes
- Coke — high-carbon fuel for steelmaking
- Cement clinker — freshly cooled kiln output
- Hot slag — byproduct of metal smelting
- High temperature aggregates — from crushers and kilns
- Metallurgical industry — steel and iron production
- Cement plants — clinker and raw material transport
- Chemical industry — high-temp process materials
- Power plants — coal ash and slag handling
- Mining & foundry — aggregate and coke conveying

Advanced Heat Resistant Rubber Compound
The cover rubber of our heat resistant conveyor belt utilizes superior ethylene-propylene (EPDM) or halogenated rubber, specifically formulated to enhance thermal resistance and dramatically reduce heat-induced aging degradation — keeping your belt performing at peak efficiency, even in the most demanding high-temperature environments.
Super Heat Resistant Conveyor Belt Grades
We go beyond standard heat ratings. Our extended grade range covers everything from standard hot material handling to extreme high-temperature industrial processes — giving you precise engineering control over your conveying system.
Cover Rubber Properties
Our heat resistant conveyor belts are classified into four internationally recognized grades — T1 through T4 — each tested at defined temperatures to guarantee consistent performance. Choosing the correct grade ensures belt longevity, reduced maintenance cycles, and safer operations under thermal load.
| Grade | Test Temp. | Thermal Level |
|---|---|---|
| T1 | ≤ 100°C |
Low
|
| T2 | ≤ 125°C |
Medium
|
| T3 | ≤ 150°C |
High
|
| T4 | ≤ 175°C |
Very High

Mechanical Properties After Heat Aging
High-temperature exposure degrades ordinary belts rapidly — causing brittleness, cracking, and catastrophic failure. Our heat resistant compound retains its core mechanical properties after prolonged thermal aging, giving engineers the confidence to specify this belt in the most demanding continuous-duty operations.
| Grade | Test Temp (°C) | Hardness Change (IRHD) | Min. Tensile Strength (MPa) | Min. Elongation at Break (%) |
|---|---|---|---|---|
| T1 | ≤ 100°C | ±8 | ≥ 20 MPa | ≥ 400% |
| T2 | ≤ 125°C | ±8 | ≥ 20 MPa | ≥ 400% |
| T3 | ≤ 150°C | ±8 | ≥ 16 MPa | ≥ 400% |
| T4 | ≤ 175°C | ±8 | ≥ 12MPa | ≥ 400% |
Where Our Belt Performs Best
From the furnace floor to the plant exit, our heat resistant conveyor belt handles the toughest material flows across the world's most demanding industrial sectors — proven across five industries and counting.
Conveyor Belt Structure
Every layer of our heat resistant conveyor belt is purposefully engineered. The result is a multi-layer composite that distributes heat, transfers load, and maintains dimensional stability — layer by layer, under conditions that destroy ordinary belts.
Why Choose Our Heat Resistant Conveyor Belt
Sourcing the wrong conveyor belt for high-temperature duty is a costly mistake — one that forces emergency shutdowns and expensive replacements. Our belts are manufactured to the exact specification your process demands, backed by decades of field-proven performance and direct factory pricing.
