Cold Resistant Conveyor Belt
Cold resistant conveyor belt can be divided into three types according to the properties of cover: Laceration resistant(H), Anti-abrasion type(D), and ordinary type(L).
According to the different cold resistance, it can be divided into two types of C1 and C2: C1-Working temperature:-45~+50℃; C2-Working temperature: -60~ +50℃. Suitable for conveying materials outdoors in freezing area, cold storage etc.
Cotton canvas, nylon canvas or polyester canvas as the belt core, covering rubber with natural rubber and butadiene rubber rubber, with high elasticity, impact resistance, cold resistance and other characteristics, can be used normally in the environment of minus 40℃.
