Product Introduction
Features and Applications: Heat-resistant conveyor belts consist of a multi-layer core made of canvas materials such as polyester-cotton or polyester, along with a cover rubber that exhibits certain heat-resistant properties. They are widely used for conveying hot materials in industries including metallurgy, building materials, coke production, casting, and chemical engineering.
Heat-resistant conveyor belts are classified into four grades according to different test temperatures:
T1—Test temperature not exceeding 100℃.
T2—Test temperature not exceeding 125℃.
T3—Test temperature not exceeding 150℃.
T4—Test temperature not exceeding 180℃.
Standard: GB/T 20021-2017 "Heat-Resistant Conveyor Belt with Canvas Core"

Manufactured with heat-resistant rubber compounds and reinforced fabric layers, the heat resistant conveyor belt can withstand elevated temperatures without cracking, hardening, or losing performance. It provides excellent resistance to abrasion, aging, and thermal damage, ensuring stable operation and long service life in demanding environments. Widely used in steel plants, cement factories, foundries, mining, and glass industries, the heat resistant conveyor belt is ideal for conveying hot clinker, coke, ore, sand, and other heated bulk materials.
