Polyester conveyor belts are made of many layers of polyester canvas to be bonded together and to be covered by wear-resistant elastic rubber. They are used to carry materials in medium or small pieces, powder or particles without special corrosion. The products are suitable for transporting materials under conditions of medium or long distance, heavy load and high speed.
Varieties: Ordinary, Acid and soda Resistant according to the nature of the cover rubber.

Heat-resistant Conveyor Belts
¡¡¡¡ Heat-resistant conveyor belts are made of many layers of polyester/cotton cloth be covered with heat-resistant rubber through high-temperature vulcanization, suitable for transporting hot coke, cement, slag and hot-casting products under 150c.
¡ñ 1¡¢ Specifications same as ordinary belt
¡ñ 2¡¢Conform to HG2297-92 standards.
¡ñ 3¡¢Heat-resistant belts are divided into three types:
¡ñ 1 type: It can stand a test temperature of 100C, code name: T1
¡¡¡¡¡¡ ¡ñ 2 type: It can stand a test temperature of 125C, code name:T2
¡¡¡¡¡¡ ¡ñ 3 type: It can stand a test temperature of 150C, code name: T3
