Cold Resistant Conveyor Belt
Basic product description
Nylon canvas or polyester canvas is used as the belt core, and the covering rubber is a combination of natural rubber and butadiene rubber. It has the characteristics of high elasticity, impact resistance, and cold resistance, and can be used normally in an environment of minus 40℃.
