Introduction
Usage
Cold resistant steel cord conveyor belts are suitable for conveying materials outdoors in freezing area, cold storage and etc.
Characteristics
The product selects steel cord as carcass. Cover rubber selects a blend of NR and BR, which has the properties of high elasticity, shock resistance, cold resistance and etc. It can work normally under the conditions of -60℃.
