|Length||: Steel cord belts 50m and over, fabric belts 10m and over.|
|Rubber Cover||: Tl , T2, T3.|
Selecting the right heat-resistant belt
- The surface temperature of the belt varies with the type and size of the material being carried. Like large lump (e.g.) sintered ores, coke),which allow air to circulate, the belt surface would be cooler than the lumps.
- In the case of powdery or similar materials. Such as cements, alumina, carbon black etc., there is almost no temperature difference between material and belt surface. Therefore, in selecting a belt, it is necessary to know not only the temperature of the material to be carried but also to have an accurate idea of the surface temperature (the belt will be operating at).
Characteristics of Heat Resistant Belt
- Rubber cover and carcass should not deteriorate due to heat.
- Rubber cover on carcass should maintain excellent properties, even at high temperatures and good adhesion to form one unit, even when they are exposed to high temperatures.
The surface temperature of heat resistant belt various with the material type, belt speed, loading rate and size depending on circumstances. In order to select the proper heat resistant belt, it is necessary to consider not only the temperature of the material to be conveyed but also the surface temperature of the belt.

Restrictions on the use of the heat resistant belt.
Do not use SBR heat resistant belt when:
- Powdered material is over 70° C.
- Strong acid or alkaline is used.
- Oil products and oil-stained substances are used.
- The operation site or the materials requires flame-resistant belts.
EPDM Heat-resistant belt
Do not use EPDM Heat-resistant belts when:
- Powdered material is over 180°C.
- Oil products and oil-stain other than vegetable oil are present.
- The location of the materials requires flame-resistant belts.
