| 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. |
