Cold resistant conveyor belt is mainly used for conveying materials in cold areas, such as open air or refrigerated warehouses under -60℃~+50℃.
The cold resistant conveyor belt is made of multi-ply rubberized nylon canvas and EP canvas as the skeleton material, covered with cold resistant coating rubber, and made by calendering, molding, curing and other processes.
This product has the characteristics of cold resistance, high elasticity, impact resistance, wear resistance, etc. it can be used normally under – 60 ℃.
