Purpose:
Ozone resistant conveyor belt is mainly used to transport bulk, granular, powdery materials or finished articles under the conditions of outdoor sun exposure and strong ultraviolet.
Structure:
Ozone resistant conveyor belt is made of multi-layer impregnated nylon canvas and EP canvas as framework material, covered with ozone resistant covering rubber, and made by calendering, molding, curing and other processes.
Features:
This product is ozone resistant and wear-resistant
