cold resistant conveyor belt
Feature
Cotton canvas, nylon canvas and polyester canvas are used as the core. The cover rubber is made of a combination of natural rubber and butadiene rubber. It has high elasticity, impact resistance, cold resistance, etc. It can be used normally under the environment of minus 40℃.
Application
It is suitable for conveying materials in open areas or frozen warehouses in cold regions.
