    Product Description

    Metal Conveyor Belting:

    Offered Metal Conveyor Belts are accessible in both polyester-nylon and nylon carcass. These belts can be composed by using grade M-24, grade N-17, grade HR, grade SHR and grade FR rubber material. In addition, offered belts are composed with uniquely mixed synthetic compounds that deliver ideal resistance to animal and vegetable oils alongside mineral. Moreover, our Conveyor Belts are intended to notify the least ensured complete thickness tensile power and various synthetic textile reinforcing piles. A nylon or polyester fabric is deployed in our belts that offer mechanically a high impact abuse and a low strength resistance.

    Key Features:

    • Highly oppose effect add accidental damage
    • The integrated fabric has the least elongation
    • Have superior adhesion construction
    • Safe to fatigue against belt flexing
