Chemical Resistant Belting
Grade CMR
This specially designed Grade of Conveyor Belting incorporates a Top Cover of Nitrile Rubber and Bottom Cover of cloroprene to withstand the chemical and abrasive action of material like Potash. Urea, etc. It also overcomes the problem of "Reverse Toughing" faced in conveying such material on Belting with normal Cover Grades.
