Heat Resistant SHR Grade Conveyor Belt
SHR belt temperature range at a glance
- HR T1: continuous 100–125°C
- SHR (HR T2): continuous 125–150°C
- HR T3: continuous up to 150°C, with peaks up to 180°C
For material hotter than this, such as hot sinter or red-hot coke, use our UHR grade (250°C and 300°C).
HILFLEX® Heat Resistant Rubber Conveyor Belts
HR T1, HR T2, SHR T3 Series
Reliable Performance for Temperatures up to 180°C
Endure the Heat. Maintain the Flow.
HILFLEX® Heat Resistant Rubber Conveyor Belts are engineered to perform where standard belts fail — in hot environments with temperatures ranging from 60°C up to 150°C and intermittent peaks of 180°C. These belts are ideal for transporting foundry sand, cement, clinker, sinter, coke, and more — ensuring durability, safety, and minimal downtime.
🔥 Formulated for Thermal Stability
Compliant with IS 1891 (Part II)
Our proprietary rubber compounds are developed to resist:
- Hardening
- Cracking
- Softening
- Surface glazing
Even in prolonged high-temperature conditions, HILFLEX® belts stay reliable and structurally intact.

Frequently Asked Questions
What is the temperature range of an SHR conveyor belt?
SHR (HR T2) is made for material at 125–150°C. For lighter heat use HR T1 (100–125°C). Where material reaches peaks of up to 180°C, use HR T3. Above that, use a UHR belt.
What does SHR mean in a conveyor belt?
SHR stands for Super Heat Resistant. It is a cover grade with a rubber compound that resists hardening and cracking from hot material.
Which materials need an SHR belt?
Cement, pellets, coke, lighter clinker and sintered ore are common SHR applications.
