Special Features:
• Excellent heat resistant and abrasion resistant cover rubber compound.
• Recommended to protect conveyor belt from surface cracking and hardening by heat.
• Specially heat-treated and dipped fabric to minimize carcass shrinkage by heat ageing.
• The Performance proven ICL America Ltd. heat resistant belt meets hot service applications like hot sintered ore, hot clinker, hot chemical, fertilizer and hot cement etc.
• ICL America Ltd. heat resistance conveyor belts are suitable for heat resistant applications where the temperature of material to be carried is over 140°F.

- The surface temperature of heat resistant conveyor belt varies with the material type, belt speed, loading rate and size depending on circumstance condition.
- In order to select the proper heat resistant conveyor belt, it is necessary to consider not only the material temperature to be conveyed but also the surface temperature of conveyor belt.
- Characteristics required for heat resistant conveyor belt are as follows:
- Rubber cover and carcass should not deteriorate due to heat.
- Rubber cover and carcass should maintain durability, even at high temperatures.
- Rubber cover and carcass should maintain good adhesion form on unit even when they are exposed to high temperatures.
